Hereinafter, a method of acquiring compensation object information from a development site using the compensation object information acquisition system 10 of the present invention will be described with reference to Figs. 1, 2, and 3. Fig.

First, in order to acquire the compensation object information for the development spot # 1 (L), which is a specific development spot to be developed, the practitioner P updates the standard information object 141 1 location information DB 1213 in the developed location # 1 area 121 is formed in the developed area compartment forming step S1 in which the compartment 121 for the developed location # 1 (L) is formed in the developed area # A developer location information input step (S2) for inputting location information on the development site # 1 (L) is performed.

Here, the location information input in the location information input step S2 includes the cadastral map for the developed location # 1 (L), the geographical or administrative boundary line, and the GPS coordinate information. At this time, the GPS coordinate information includes the X, Y, and Z-axis three-dimensional spatial coordinates of the space of the development site # 1 (L).

If the location information of the development location # 1 (L) is stored in the development location # 1 location information DB 1213 according to the step S2, the drone operation unit 150 stores the location information DB 1213 (S3) of flying the drones 200 to the development site # 1 (L) using the location information stored in the development site # 1 (L). This flight step S3 continues until the drill 200 can reach the development site # 1 (L).

When the drones 200 arrive at the development site # 1 (L) according to the flight step S3, the drones 200 acquire the development site # 1 (L) L, and after moving to the center coordinates, a position alignment step S4 of confirming the equilibrium state thereof using the posture control sensor 232 is performed.

In the aligning step S4, the center coordinates may be calculated by the dragon operating unit 150 on the basis of the development location # 1 location information 1213 and transmitted to the dragon 200. Accordingly, the drones 200 are positioned at the center of the developed paper # 1 (L) using the transmitted center coordinates and their own GPS 231.

When the drone 200 is positioned at the center of the development location # 1 (L) through the alignment step S4 as described above and the alignment is completed, the drone 200 photographs through the photographing unit 210 of the drone 200 , And a photographing step S5 for acquiring image information is performed.

In the above description, the image information includes photographs, moving images, and all other information that the practitioner P can recognize.

After the drones 200 acquire the image information for the development location # 1 (L) in the photographing step S5 as described above, the image information transmission step S6 for transmitting the image information to the base station server 100 is performed .

In the image information transmission step S6, the image information transmitted to the base station server 100 is transmitted to the developed # 1 image information DB 1212 in the previously allocated development # 1 section 121 by the controller 110, / RTI >

After the completion of the image information transmission step S6 as described above, if the drones 200 are scheduled to move to another development site to be used or are moved from the base station server 100 to another development site in real time When the request is received, the drone 200 performs the flying step S3 again to move to another development site, and sequentially performs the above-described steps S3 to S6 again. ) If you do not have a development area to return to, you will return to base. The movement, photographing, and return operation to the above other development sites have already been described above, and they are general operations, and a description thereof will be omitted.

1 position information DB 1213 with respect to the image information transmitted through the image information transmission step S6 and stored in the developed image # 1 image information DB 1212, , A position information display step (S7) of displaying position information on the image information is performed.

According to the location information display step S7, the location information is displayed in the image information. The location information includes the cadastral map, the boundary line, and the GPS coordinates information for the development site.

After the position information display step S7 has been performed, the compensation object extraction unit 130 refers to the standard compensation object information 141 already stored and stores it in the development place # 1 video information DB 1212 Extracts the compensation object (C) from the image information, and performs compensation object extraction step (S8) for generating compensation object information based on the compensation object (C).

Here, the method of extracting the compensation object may be implemented using an image processing method. This may be implemented using a well-known Image Registration algorithm or the like. In particular, as described above, since the pair of cameras 211 and 212 are provided in the photographing unit 210 of the drone 200 and a pair of comparable images are included in the image information, The image attribute information such as the image edge and the pixel value of the compensated object can be automatically extracted from the image information of the target development site which is easily photographed by analyzing the pair of images through the image matching method described above. Accordingly, the compensation object extraction unit 130 includes at least one program for implementing the image matching algorithm.

Since the geometric characteristics and the pixel values of the compensation object to be compensated as standard are stored in the standard compensation object DB 140, the image property information of the compensation object extracted from the developed image and the compensation It is possible to automatically identify the type of the object by automatically matching the geometric characteristics and pixel values of the object.

Since the positional information, in particular the boundary line of the development area, is recorded in the video information to be extracted of the compensation object, the compensation object within the recorded boundary line is extracted.

The compensated object information generated based on the compensated object C extracted by the compensated object extracting unit 130 may include information on the standard compensated object such as the building, the tree, the manure, (C) of all types that can be extracted through the use of the compensation object (C), the type of the compensation object (C), the coordinates of the compensation object (C) The height, the length, and the like.

When the compensated object information of the development site # 1 (L) is extracted through the above-described compensation object extraction step (S8), a copy of the land register or the real estate register for the extracted compensation object (C) (Hereinafter referred to as " registration information ") from the outside and updates the compensated object information (S9).

At this time, it is common that a third party who is not a landowner does not view or only a part of the information is disclosed, but a copy of a real estate registration book in which the land register or registration information is recorded, As the applicant of the invention, Chungbuk Development Corporation can receive complete data and related meta data of registration information such as the land register, real estate, and landmark through the public office as the subject of the development business, (S9) can be performed.

According to the compensation item matching step S9, the base station server 100 receives the registration information from the outside of the government office or the like, stores the registration information in the compensation item list DB 1211 of the development place # 1 zone 121, The compensation object extraction unit 130 updates the compensation object information generated by the compensation object extraction unit 130 with reference to the registration information about the compensation object C extracted by the compensation object extraction unit 130. [

In the compensation object matching step S9, the compensation object extraction unit 130 extracts the address information of the compensation object C shown in the form of an address in the form of an address on the registration information, The compensation object extraction unit 130 determines whether or not the compensation object C has the address mismatch of the compensation object C through the display 160. In this case, To the practitioner (P).
