Description

Apparatus for Measuring of National Level Control Point using and Visual Information in Geodetic Surveying}

The present invention relates to a national level reference point surveying apparatus using image information acquisition in geodetic survey, and in detail, the foot is installed in the ground according to the state of the ground further drawn out from the lower end of the surface to adjust the height The present invention relates to a national level control point surveying apparatus using image information acquisition in geodetic surveying, which is capable of emitting infrared light when the amount of ambient light is insufficient when acquiring image information.

Leveling and plane surveys are used to determine heights in three-dimensional coordinates and to observe elevations or elevations between points on the surface. The national benchmark is based on mean sea level (geoid), and the results of the level survey are important information that provides data for mapping, design, and construction.The design of roads, railways, canals, construction of planned structures, and drainage It serves as a reference point in the fields of characteristic research and mapping. The national standard level reference point survey is carried out in accordance with the provisions of Article 39 and 40 of Chapter 3 Level Survey No. 2002-177 of the Ministry of Construction and Transportation, and goes through the work planning, preemption, installation of the survey table, observation, calculation, and performance management. Is for fast and accurate national level control point surveys in the observation phase.

Observation is an operation to measure the height difference between related points by level and level marking along the observation plan chart based on the preemptive diagram, and the scale of the observed scale is recorded in the field of paper form in numerical form. Information can be obtained through image information to prevent incorrect reading of numerical values due to the mistakes of the observer until the scale of the scale is read, read, and written on the field.

This conventional geodetic surveying method will be described with reference to FIG.

1 is a diagram illustrating a national level reference point surveying apparatus using image information acquisition in a conventional geodetic survey.

Referring to FIG. 1, the surface water sets the surface 10 at the ground reference point a0 where the surface water 1 is known, and the number of machines moves from the first observation point b1 away from the first observation point b1 to the level 2. Read the scale of the scale (10). Here, the level unit can acquire image information.

After that, the surface water moves to the first point a1 to establish the surface 1, and the mechanical number reads the scale of the surface of the first point 1. Here, the altitude of the first point a1 is obtained from the difference between the scales read from the ground reference point a0 and the first point a1 and the elevation of the ground reference point.

Next, the machine moves to the second observation point (b2) after the first point (a1), and then, after the surface number is turned in place, the surface (10) faces the leveler (20). The machine number reads the scale of the scale 10 with the leveler 20.

Thereafter, the surface water moves to the second point a2 to establish the surface 1, and the mechanical number reads the scale of the second point surface 1. Here, the altitude of the second point a2 is obtained from the difference between the scales of the first point a1 and the second point s2 read at the second observation point b2.

In this way, the top and bottom levels 1 and 3 are continuously moved, and the directions of the top and bottom levels 1 and 2 are read at each point to read the scale to obtain the altitude of each point up to the target point. .

However, since it is necessary to read the scale by changing the direction of the top surface in place, various errors occur according to the state of the ground. In addition, the error at each point may be only a few millimeters, but when surveying the entire surveyed area, a huge cumulative error occurs, and a few millimeter error is not allowed in a first- or second-level survey that requires precise surveying. .

As shown in the first point of FIG. 1, the general surface 1 has a rectangular cross section. Therefore, there is no axis of rotation when rotating the top surface in the ground. So when turning, the surface water lifts the scale bar and rotates it, and then it is difficult to put it in the correct position. And the ground is often inclined, and in our view, the flat ground is also inclined.

Therefore, there was a problem in that an error occurred in the altitude (standard) measured when the position was changed because the surface number was not placed in the correct position in the process of lifting the surface (1).

In addition, since the conventional leveler 2 depends only on the visible light condition of the surroundings, for example, in the case of night work or cloudy weather, the image information recorded is not clear and the ruler of the standard is not accurately photographed. The lighting device or the leveler 2 itself is provided with a visible light emitting device.

However, such a visible light emitting device is supplied with power from a power supply device of a level device capable of acquiring image information, but is limited in its capacity, and also consumes power in accordance with the light emission output of visible light. There is a problem that must be provided with a spare battery.

The present invention has been made to solve the above-mentioned conventional problems, the object of the present invention is to obtain the image information during the surveying of the level reference point and the level can be installed in a balanced position even in the situation of uneven ground The present invention provides a national level reference point surveying apparatus using image information acquisition in geodetic surveying, which is capable of capturing image information by infrared light, even in a situation where the amount of ambient light is insufficient.
