System and method of managing a landscape remotely using the CCTV}

The present invention relates to a landscape management system and method, and more particularly, landscaping at a remote location using CCTV that can remotely check and manage the condition of trees through a CCTV camera capable of PTZ (Pan / Tilt / zoom) control. It relates to a management system and method.

Everyone agrees that one of the most serious problems we need to solve in the 21st century is the urban environment. The environment is the most important basic unit of man, and urban environmental problems, which can be classified into water pollution, air pollution, waste disposal, noise and vibration, and green land destruction, are not only economic growth of the city, but also political, economic, social, and cultural factors. The situation is threatening the quality of life of urban life.

In recent years, a lot of money has been invested in green spaces for green cities, where the price of landscaping trees ranges from hundreds to tens of millions of won per tree. The current tree management policy is managed directly by the management company or the city. However, the management of such trees requires a lot of labor costs, and if not systematically managed, expensive trees can suffer from a lot of economic loss due to illness or death.

Due to the deterioration of the roadside growth environment due to urban concentration and lack of awareness of roadside trees, damages such as death and malformation have been increasing.However, it is difficult to accurately grasp the growth information of individual roadside trees, and effective response to roadside complaints is insufficient. .

On the other hand, when the tree is to be managed remotely through a CCTV camera, the position of the tree is fixed, and since the change state is considerably slow, there is a problem that it is difficult to easily check with the naked eye. In addition, there is a problem that management of trees through CCTV cameras is not easy because it is difficult for an inexperienced manager to clearly grasp the growth situation of trees only with low resolution images.

Alternatively, if the tree is managed by using the RFID tag, which is a local information providing means, the management cost is not only high, but it is not easy to manage continuously, and when the RFID tag is used, the amount of information to be managed is small. there is a problem.

Meanwhile, the cameras 250 may be connected to the service server 200 through the network 220 to transmit a controlled and photographed image. In this case, the signal for control and image information captured in real time may be converted into a TCP / IP protocol signal and transmitted through the Internet network 220. Alternatively, the cameras 250 may be directly connected to and controlled by the service server 200 through wired cable means or the like.

Hereinafter, a landscape management server and a landscape management procedure according to an embodiment of the present invention will be described in detail with reference to FIGS. 3 and 4.

3 is a diagram illustrating a detailed configuration of a service server according to an embodiment of the present invention. Referring to FIG. 3, the landscape management server 201 of the service server 200 according to an exemplary embodiment of the present invention may include a camera controller 311, an image photographing unit 312, an image analyzer 313, and a tree information input unit ( 314, the tree state determination unit 315, the job notification unit 316, the QR code generation unit 317, and the image reproducing unit 318. In addition, the database server 203 may be configured of a tree-related information database 321, a captured image information database 322, an analysis-related information database 323, a task-related information database 324, and the like.

First, the camera controller 311 generates a control signal for the plurality of cameras 250 to control the cameras 250. In particular, according to the present invention, since each camera 250 basically supports the PTZ function, it controls the PTZ for each camera 250. For example, when a unique number for a specific camera and a control signal for up, down, left, or right zoom functions of the camera are generated and transmitted to the camera, the camera operates according to the received control signal as described above with reference to FIG. 1. Done.

The image capturing unit 312 performs image capturing of each camera 250 in cooperation with the camera controller 311. At this time, since the change state of the tree is considerably slow, it is preferable to control to shoot an image by setting a certain period according to the embodiment of the present invention. Therefore, the image capturing unit 312 controls each camera 250 to capture an image according to a set period.

On the other hand, when identifying the tree object through the first image capture, each camera 250 periodically moves the fixed surveillance area, and receives the position of the tree as a region in the fixed surveillance image for each position to be initially set. In this case, the image information photographed according to the photographing control of the image capturing unit 312 is received from the camera 250 to the service server 200 through a network 220 or a wired line, the received image information is an image The analysis unit 313 analyzes.

The image analyzer 313 identifies each tree object from a captured surveillance image by a predetermined image processing method, and stores area information on the identified tree object for an image captured at a specific fixed camera position. It is used to identify the tree object. That is, the image captured at the same pan value, tilt value, and zoom value for each camera includes the same tree object at the same position.

In this case, a plurality of trees photographed in one image may be classified by assigning serial numbers according to a predetermined rule (for example, from left to right). On the other hand, if the area of the tree with the lower number overlaps with the area of the tree with the higher number, the tree is implemented to determine the corresponding tree except for the overlapped area (that is, only visible parts). Instead, it is preferable to photograph the exposed trees more closely by zooming the exposed area, and it is also possible to generate a single image by combining a plurality of captured partial images.

As such, when each tree object is identified through the image analyzer 313, the tree information input unit 314 receives various information about the tree, links the tree with the identified tree, and links the tree-related information database 321. Store in The information on the tree may include a kind of tree, existence of survival, age, medical history, drinking water, and the like. Accordingly, the tree-related information database 321 includes an identification number uniquely assigned to each identified tree, and an identification number of the camera, a pan value of the camera, and a tilt so that the tree can be identified through the captured image. A value, a zoom value, and a position (eg, pixel information, etc.) in the corresponding image are linked and stored together.

Thereafter, the image capturing unit 312 periodically captures an image as described above to monitor a corresponding shooting area, and controls a pan value, a tilt value, and a zoom value for each tree object identified in each monitoring target area. The images of the individual trees are captured and saved by zooming. For example, when there are 10 identified tree objects included in a shooting area photographed by a specific camera, the position of the camera is moved around each tree object by pan and tilt control, and the image is zoomed and photographed for the tree object. In addition, high-quality images of each tree are captured.

High-quality image information of each captured tree is accumulated and stored in the captured image information database 322. Meanwhile, when image information photographed for a predetermined period is accumulated, the tree state determination unit 315 compares the image of each tree during the predetermined period with the image information previously stored in the analysis related information database 323. It is determined whether the trees are abnormal. For example, by determining the color change, size change, shape change (eg, bending, etc.) of the tree, it is determined whether or not abnormality.

When an abnormality is detected as a result of the determination by the tree state determination unit 315, the abnormality is notified according to a preset method. That is, the administrator terminal may notify the abnormality of the specific tree or the predetermined administrator's mobile phone or smartphone via the text message or the like. For example, through the information stored in the analysis-related information database 323, it was confirmed that the average judgment information of species A increased by 10% on the basis of one month's image. If it is missing or small, it may be determined that the trees have abnormalities. In addition, the information related to trees for many years is formed in the analysis-related information database 323, and the analysis is compared and compared with the change in the green distribution compared to the previous year and the average distribution between the last 5 to 10 years to apply the criteria for the determination of tree abnormalities. It may be. In addition, if the number of species A is below the standard, additional information may include basic growth information. However, because the use of the status of other species reflects the specific individual environment, the reliability is high, so that non-experts in the tree can cope with the abnormal situation.

On the other hand, the job notification unit 316 informs the work instruction through a predetermined means when a corresponding work schedule arrives for a particular tree group according to the preset work schedule. In this case, information related to various job schedules and job results may be stored in the job related information database 324.

In addition, the job notification unit 316 may be connected with various environmental sensors to receive water from the environmental sensor and perform watering control when a predetermined condition is satisfied.

The QR code generation unit 317 generates a QR code from information on each identified and managed tree object. As described above in the description of FIG. 1, the generated QR code is output and attached to the corresponding tree. In this case, when the attached QR code is scanned through a smartphone or the like, the scanned information may be analyzed to easily obtain information on the corresponding tree. In addition, the smart phone 210 to access the service server 200 through the scanned information, and read the information of the tree previously stored in the tree-related information database 321 in the service server 200 to the smartphone 210 may be provided.

For example, in the case of the Arboretum, as described above, the function of outputting the QR code including the online location information and the basic information of the corresponding tree to provide the relevant information may be added to enable the online interlocking management only with the output of the corresponding code. .

In addition, in the case of the Arboretum, all history related to the tree is included in the code in the form of text when the tree is shipped, and if necessary, the image information including the main meat image may be further provided through the link as described above. Through this, it is possible to easily check the information of the tree only with a regular smartphone or tablet PC without any additional device, and it is possible to effectively manage the tree at low cost because it uses a printed material which is cheaper than RF tags.

The image reproducing unit 318 performs a function of automatically editing image information of each tree stored in the captured image information database 322 and interlocking the growth of the corresponding tree like a video. At this time, the intuitiveness can be enhanced by displaying the work history and the like on the position slide bar of the video.

4 is a flowchart illustrating a landscape management procedure at a remote location using CCTV according to an embodiment of the present invention. Referring to FIG. 4, when an image of each region is photographed by each camera installed as described above (S401), the tree object is identified by analyzing the image photographed by each camera through a predetermined image processing process (S402). do.

Thereafter, information about each identified tree object (eg, tree type, survival, age, medical history, drinking water, etc.) is input and stored in a database (S403).

Thereafter, the camera photographs each region periodically through the photographing control of each camera, and captures and stores a high quality image (S404) for each of the tree objects identified in the photographing region through a zoom function. As such, when the photographed tree object image is accumulated for a predetermined time, it is determined whether the tree is abnormal by comparing and analyzing the stored image or data (S405).

As a result of the determination, if it is determined that an abnormality has occurred in the tree (S406), the corresponding abnormality is notified according to the set method (S407). In addition, when the set work schedule arrives as described above (S408), the work schedule is notified according to the set method similarly (S409).

On the other hand, in the embodiment of the present invention has been described with respect to specific embodiments, various modifications are possible without departing from the scope of the invention. Therefore, the scope of the present invention should not be limited by the illustrated embodiments, but should be determined by the scope of the appended claims and equivalents thereof.
