Description

[0001] The present invention relates to a numerical information updating system for correcting error numerical information immediately,

More particularly, the present invention relates to a numerical information updating system for immediately correcting error numerical information, and more particularly to a numerical information updating system for correcting error numerical information by a first and a second horizontal adjusting means in a field in which numerical information (coordinate information) Since a large number of GPS antennas are installed on the disk, the distance from the satellite is always kept the same, and the numerical information (coordinate information) of the site is precisely received The present invention relates to a numerical information updating system for immediately correcting error numerical information by enhancing precision of a digital map.

It is an image of the topographic map of the ground using the ground image taken from the aircraft. It is a numerical map that reflects coordinate information, position information or numerical information by numerical values at each point of the map. It is generally manufactured by a drawing method or a numerical value drawing method.

All terrain features on the ground can be partially changed due to large-scale construction, etc., and numerical maps that digitize the image of drawings should update or update numerical information (coordinate information) of the changed areas from time to time.

Since aerial photographs are taken using aircrafts that require high maintenance costs and all the images taken are required to be individually inspected by national agencies such as the National Intelligence Service, it is very cumbersome and time consuming in terms of cost and procedural aspects It is common.

In addition, the topographical features of the ground can be changed by construction, development, construction, etc., and the shape of the landforms in some areas may be changed from time to time, and repeating the expensive aerial photographing may be burdensome.

On the other hand, the photographed image is difficult to be photographed in a perfect plane even when an aircraft is used, and in a region where high-rise buildings are concentrated due to optical limitations such as a curvature (distortion factor, distortion rate) It is common to include flexion.

That is, a plurality of photographed images or picture images, which are photographed and partially distorted, are synthesized and edited as one integrated image, and the numerical information applied to the picture image produced by such an integrated image may have a partial error, Update is required.

Therefore, it is necessary to measure the accurate numerical information (coordinate information) of the site in order to solve the error of the digital map due to the distortion of the figure image due to the partial shape feature change by the construction etc. and the curvature of the lens, have.

As an example, a system and a method for producing a digital map using a GPS and an ES are disclosed in Patent Registration No. 10-0558367 (registered on Mar. 28, 2006) have.

Each of the GPS sensor 100 and the UI sensor 110 is installed on an aircraft to measure movement path information of an aircraft and output it to the control means 130. [

On the other hand, the camera 120 is mounted on an aircraft, photographs the ground for map production, and outputs it to the control means 130.

The control means 130 adds time information to the photographic image photographed by the camera 120. [

Meanwhile, the control means 130 complements and processes the position information input from the GPS sensor 100 and the position information input from the UI sensor 110 in a Kalman filtering manner at the time the photographic image is captured.

The control means 130 applies numerical information (positional information) complementarily processed by the Kalman filtering method to coordinate information on the center position of the photographic image to complete the digital map.

The picture-taking camera (120) shoots at 50-60 frames per second and images 60% overlap so that distortion of the camera lens and distortion due to the photographing angle are generally compensated as much as possible. However, Distortion still remains.

Conventional art has the advantage of improving the accuracy because it calculates the center coordinates of an image taken on an aircraft by using the information of the GIS and ES, but it does not solve the distortion or distortion occurring at the edge of the photographed image, There is a problem that the reliability of the numerical information (coordinate information)

Therefore, it is necessary to develop a technique to accurately update the balance information (coordinate information) of the topographical feature in the field and partially apply it to the digital map so as to quickly update and correct it at a low cost.

Each of the first through third fiber module modules includes a GPS receiver, a movement direction analysis module, a movement speed analysis module, a hardness analysis module, a latitude analysis module, and a sea level analysis module.

The improved prior art has the advantage that the numerical information (coordinate information) on the field where there is an error in the numerical information in the digital map is measured and reflected quickly.

However, in the improved prior art, when the vehicle travels in an inclined section in the forward and backward directions and the lateral direction in the course of traveling, the disc portions are inclined in the corresponding directions, and the height of the respective SAW antennas provided on the disc portion are different from each other.

That is, the distances between the GPS satellite and the first to third GPS SOAs are different from each other due to inclination of the disk, and the first to third GPS SOAs generate different position information (coordinate information) There is a problem that a precise numerical map can not be produced.

Therefore, it is necessary to develop a technique for always keeping the disk constant in the horizontal portion even in the region where the bending in the front-back direction and the lateral direction is severe.

The altitude value calculation unit 1238 receives the altitude analysis values of the places where the vehicle actual side unit 1000 is currently located, which are respectively analyzed from the first to third altitude analysis modules 890, Of the sea level to 3 times or more.

The coordinate values composed of the moving direction, the moving speed, the latitude, the hardness, and the sea level output from the GSPS processing unit 1230 are applied to the control unit 1220 as the first coordinate information.

The LVS processor 1240 is configured to receive location information of the mobile communication unit through the mobile communication system 3000 registered with the mobile communication unit 1260.

The horizontal sensing sensor 1270 senses the level of the mounting board 1111 and transmits the sensed horizontal level to the control unit 1220. The control unit 1220 controls the horizontal And the horizontal adjustment motor driving unit 1280 analyzes the command signal inputted from the control unit 1220 and transmits the corresponding control signal for rotating the horizontal adjustment motor unit 1180 in the forward direction or the backward direction, .

In this case, the control unit 1120 controls the horizontal adjustment motor unit of the plurality of horizontal adjustment motor units 1180 to rotate in a clockwise direction in a plan view according to the detection signal of the horizontal detection sensor 1270, The horizontal adjustment motor portion is raised by the screw action of the male screw portion 1191 of the horizontal adjustment screw 1190 engaged with the female screw portion 1182 of the upper horizontal adjustment motor 1181, So that the horizontal adjustment screw 1190 is lowered by the screw action of the male screw portion 1191 of the horizontal adjustment screw 1190 engaged with the female screw portion 1182 of the motor shaft 1181 do.

Here, it is assumed that the communication network 3000 is the same as a mobile communication system (hereinafter, referred to as a " communication network ") and includes a wired communication network and the Internet. A mobile communication system is generally known and will not be described in detail.

The communication network 3000 should confirm the position of the mobile communication unit 1260 or the mobile terminal (hereinafter, referred to as "mobile communication unit") based on its operating characteristic, with the base station (BS) as its center.

The base station is a direct connection of the mobile communication unit 1260 by radio, forming a certain service area, and a plurality of base stations are continuously installed at regular intervals to form a nationwide service area.

The communication network 3000 must calculate the direction of movement of the mobile communication unit 1260 and handover the base station located in the direction of moving based on the currently connected base station to allocate a channel to be connected to the mobile communication unit 1260, It is necessary to specify the time point at which the handover is calculated by calculating the moving speed.

The communication network 3000 should always check the location information of the mobile communication unit 1260 in the moving state according to the operational characteristics.

At this time, the communication network 3000 confirms the position of the mobile communication unit 1260 around the position of the base station, and the coordinate information of the base station is already known accurately.

When three base stations around the mobile communication unit 1260 calculate the straight line distance to the mobile communication unit 1260, the position of the mobile communication unit 1260 can be accurately measured by the triangulation method.

The service for confirming and providing the coordinate information on the position of the mobile communication unit 1260 around the base station already knowing the coordinate information is called an LBS (Location Based Service) service.

The LBS processing unit 1240 requests the LBS service to the communication network 3000 connected to the mobile communication unit 1260 and provides the location information of the mobile communication unit by the LBS service provided by the communication network, And also applies the same to the control unit 1220 as the second coordinate information.

The control unit 1220 records the first coordinate information applied from the laser processing unit 1230 and the second coordinate information applied from the laser processing unit 1240 in the allocated area of the buffer unit 1250, Average operation.

A plurality of programs, operation parameters, operation data, and the like are recorded in the buffer unit 1250 and can be retrieved by the corresponding control signals of the control unit 1220.

The coordinate values obtained by arithmetic mean calculation by the control unit 1220 are referred to as average coordinate values.

The control unit 1220 encrypts the average coordinate value arithmetically averaged in the specified data format.

The data format can be classified into an overhead area, a field area in which average coordinate values are recorded, a check area to search for errors, a time area in which time information is recorded, and the like. Can also be encrypted.

(Decryption) can not be performed unless the order in which the respective regions of the data format are arranged, the size of the data that can be allocated and recorded, and the data size of the entire frame are known.

The control unit 1220 applies the average coordinate value encrypted in the data format to the mobile communication unit 1260 in real time and the mobile communication unit 1260 transmits the average coordinate value to the drawing update server 4000 through the communication network 3000 in real time .

On the other hand, the control unit 1220 may receive a control command signal from the drawing update server 4000. [

The drawing update server 4000 decodes the received data format in real time to extract an average coordinate value and quickly updates the average coordinate value received in the corresponding area of the existing digital map being managed.

In this configuration, since the vehicle actual sensing unit 1000 measures the precise coordinate information of the scene in real time while traveling on a site requiring updating of the coordinate information, and transmits it to the picture updating server 4000 in real time via the communication network, the picture updating server 4000 There is an advantage that the coordinate information (numerical information) can be reflected and updated in real time.

On the other hand, there is an advantage that there is no possibility of an error because it is encrypted and transmitted.

Also, there is an advantage in that the accuracy is increased to three times or more since arithmetic mean calculation is performed on the values obtained by constituting each of the first to third pieces of the GPS receiver 840.

Further, the laser-receiving portions 840 are installed on the disc portion 1130 at equal intervals (uniform intervals) of 120 degrees, and the left and right rotations of the disc portion 1130 are repeated by any one of the elapsed time and moving distance It is possible to eliminate the error caused by the reception antenna installation position of the GPS receiver 840 and to receive the GPS signals received from the respective reception antennas under the same condition.

The Global Positioning System (GPS) 2000 is composed of 24 GPS satellites operating at an altitude of 20 to 25 km (Km) above ground, preferably at an average altitude of about 20,183 km, Is a global positioning system that broadcasts free-of-charge GPS signals that can be analyzed by sea level, longitude, latitude and time. On the other hand, the GPS signal processor 1230 must receive the GPS signal from at least three GPS satellites 2000 to analyze position information.

The communication network 3000 is a general structure including all types of communication networks such as a mobile communication network, a wireless communication network, a wired communication network, a data communication network, and the Internet.

The drawing update server 4000 is connected to the vehicle actual side part 1000 and the communication network 3000 including the mobile communication system and receives the positional information and applies the same to the corresponding portion of the picture image. Based on the applied part, The coordinate value data of the entire digital map can be updated.

According to an embodiment of the present invention, a method of operating a numerical information update system for immediately correcting error numerical information will be described in detail. The control unit unit constituting the coordinate processing unit searches the buffer unit and loads operation parameters, data, etc., Set the activation state.

The control unit analyzes the loaded information (data, parameters) and judges whether it is set to control based on elapsed time or to control based on the moved distance.

If it is determined that the control unit unit is set to control based on the elapsed time, the elapsed time information after the field measurement unit starts to be operated in the field is continuously analyzed in real time.

The control unit may change the driving direction of the step motor unit from forward rotation to reverse rotation in a predetermined unit of time specified by the information loaded by the analyzed elapsed time information in real time, And outputs the corresponding control signal.

On the other hand, if it is determined that the control unit unit is set to control based on the distance traveled, the moving distance information after the field measurement unit starts to be operated in the field is continuously analyzed in real time.

The control unit unit controls the driving direction of the step motor unit in the forward direction rotation direction to the reverse direction rotation direction in units of a predetermined set distance designated by the information loaded by the moving distance information analyzed in real time, And outputs the corresponding control signal for controlling the switching.

The control unit unit controls the geofust treatment unit to output corresponding control signals for real-time analysis of the geofos information received by the first to third geoface-receiving units in accordance with the moving direction, moving speed, latitude, longitude and altitude.

The control unit outputs a corresponding control signal for arithmetically averaging and outputting the analyzed information in real time.

The control unit outputs a corresponding control signal for real-time calculation of the arithmetic mean value to be transmitted to the drawing update server or the specified counterpart in real time by mobile communication.

The apparatus operated in this way has an advantage that no error is caused by the installation position of the GPS reception antenna.

In addition, the arithmetic average of the analysis values of the received pieces of information of the pieces of paper-side information received by each of the three laser module modules is improved, so that the first coordinate information finally output is improved to an accuracy of three times or more, and the first coordinate information and the second coordinate information The accuracy is improved to 6 times or more as a whole.

In addition, since the numerical information updating system for immediately correcting the error value information according to the present embodiment includes the first and second horizontal adjustment means 1500 and 1600, the first to third DSS antennas 810, 820 and 830, Is always placed on the flat plate of the same height.

That is, when the ground surface is inclined forward or backward or tilted left and right in the process of moving the vehicle on which the vehicle body side portion 1000 is mounted, the first to third dust- The height of the first to third SAW antennae 810, 820 and 830 are different from each other. At this time, the mounting plate 1111 mounted on the mounting plate 1111 is tilted, The sensor 1190 senses the level of the mounting plate 1111 and outputs a sensing signal and the control unit 1220 drives the plurality of horizontal adjustment motor units 1180 according to the sensing signal of the horizontal sensing sensor 1190. [ The motor shaft 1181 of the horizontal adjustment motor unit in the lower position of the motor shaft 1181 is controlled to rotate clockwise when viewed from the plane so that the number of the horizontal adjustment screws 1190 engaged with the female screw unit 1182 of the motor shaft 1181 By the screwing action of the threaded portion 1191, The upper horizontal adjustment motor unit is controlled to rotate in a counterclockwise direction in a plan view so that the horizontal adjustment motor unit can be rotated in a horizontal direction The horizontal adjusting screw 1190 is lowered and separated from the upper side of the mounting plate 1111 by the screw action of the male screw portion 1191 of the screw 1190.

At this time, since the mounting plate 1111 is supported by the three-dimensional rotating body 1160 and the three-dimensional rotating supporting bodies 1171 and 1173 so as to be three-dimensionally rotatable relative to the fixing plate 1112, So that the first to third laser SAR antennas 810, 820 and 830 are always maintained at the same height.

Meanwhile, in the process of maintaining the mounting plate 1111 horizontally by the first horizontal holding means 1500, delay occurs during detection of the corresponding signal, control, and operation of each component, .

It is a technical idea of the present invention to further include a second horizontal holding means 1600 as a constituent for compensating for such a problem, so as to quickly cope with the curvature of the terrain.

A structure for stably fixing or installing the grip portion 1630 at a specific position, a bracket and the like are generally known easily, so a detailed description will be omitted.

The liquid 1670 mounted inside the grip unit 1630 is preferably relatively dense to enhance the buoyancy of other objects (fixed plate, mounting plate, etc.), but it is generally dense, (For example, mercury or the like) that can increase the buoyancy of the water. The grip portion 1630 may further include a general configuration for preventing the liquid 1670 from flowing out.

The mounting plate 1111 and its configuration and the first horizontal holding means 1500 constitute the second horizontal holding means 1600 and are quickly leveled even in a curved form by the center weight 1626 located in the liquid 1670 do.

Four switch levers 1640 are provided on the fixed plate 1112 at an equal angle with respect to the attached drawings and four flow restricting portions 1660 are provided at the middle portion of the depression 1630 Respectively. However, if necessary, three, five, or six or more of them may be provided to precisely restrict the flow.

When it is determined that the corresponding signal is input from the three or more upper limit sensors 1664, the control unit 1220 controls the plurality of horizontal adjustment motor units 1180 The control unit 1220 may not input a signal detected from the horizontal sensing sensor 1270 or may input the signal later.

The control unit 1220 controls the horizontal adjustment motor unit 1180 at the corresponding position to rotate in the corresponding direction until a signal is not detected from the upper restriction projection 1664 when a signal is detected from the upper restriction projection 1664 . That is, the control unit 1220 controls the horizontal adjustment motor unit 1180 to preferentially operate the signal detected from the upper limit protrusion 1664 rather than the signal detected by the horizontal detection sensor 1270.

The process in which the control unit 1220 is operated by the signals detected from the three or more lower limit sensors 1665 corresponds to a method in which the mounting plate 1111 is horizontally aligned with the signal of the upper limit projection 1664 A detailed description will be omitted.

That is, the time required for the second horizontal holding means 1600 to maintain the horizontal state is faster than the time required for the first horizontal holding means 1500 to maintain the horizontal state, and such physical phenomenon is well known.

However, the flow restricting portion 1660 restricts the flow range since the second horizontal holding means 1600 may generate a flow (vibration) while maintaining the horizontal position.

Therefore, the disc portion 1111 on which the plurality of the SAW antennas 810, 820 and 830 are installed is always kept horizontal, and accordingly, the plurality of the SAW antennas 810, 820 and 830 provided on the disc portion 1111 are always the same It is possible to accurately receive the information of the GPS signal and to produce an accurate numerical map.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is evident that many alternatives, modifications and variations will be apparent to those skilled in the art.
