Description

An air photograph renewal system reflecting change of geographic feature}

The present invention relates to a space image painting system, and more particularly, to an aerial photograph when an aircraft fixed to an aerial photographic camera provided in an aircraft for photographing the ground is subject to a change in aircraft attitude due to flight speed adjustment, altitude adjustment, turning, etc. The present invention relates to a spatial image drawing system capable of realizing video images according to changes in spatial information capable of capturing an intended position on the ground with a minimum of error by minimizing a change in a camera's shooting angle.

The drawing image, which is the background and standard of the digital map, is produced based on the aerial photographed image. That is, a drawing image is created using the aerial image obtained from aerial photography, and a digital map is finally completed by combining location information such as GNSS/INS and various spatial information with each location of the drawing image.

Therefore, in order to produce accurate digital maps, it is most important to collect accurate aerial images.

1 is a functional configuration diagram illustrating an aerial photographing state according to an embodiment of the prior art.

Hereinafter, in detail with reference to the accompanying drawings, in aerial photography, a high-performance camera member 10 having a high magnification and high resolution installed in an aircraft P performs ground photography at a certain altitude several times per second, and such ground photography is performed. Among the aerial photographic images collected through this process, the optimal aerial photographic image that can be applied to digital map production is selected and converted into a drawing image.

Since the aircraft (P) is a device that navigates the sky (sky) at a constant speed, the posture of the aircraft (P) may not be stable and may change depending on the altitude and steering adjustment of the aircraft (P), atmospheric pressure and climate change, etc. Since the change in posture of the aircraft causes a change in the shooting angle of the camera member 10, the camera member 10 cannot accurately capture the intended position on the ground without error, and the ground image captured with such an error is obtained. There was a problem of including optical errors in the drawing image.

In order to partially solve this problem, conventionally, the camera member 10 is connected to the body of the aircraft P by a pivot structure, so that even if the body rotates (rotates) back and forth, left and right, the weight of the camera member 10 causes the corresponding gravity. A technology has been proposed to maintain the state independently of the gas while maintaining the direction.

However, even if the camera member 10 is fixed independently of the body of the aircraft P, inertia affects the camera member 10 according to the speed control or steering adjustment of the aircraft P, rather the camera member 10 There was a problem with more shaking. That is, when the speed of the aircraft P suddenly decreases or the aircraft P suddenly turns, the camera member 10 rotates in a direction different from that of the aircraft P due to its own inertia, and the shooting angle changes greatly. , and through this, the problem of not being able to photograph the intended subject occurred.

Eventually, the effect of inertia on the camera member 10 according to the flight behavior of the aircraft P causes the camera 310 to photograph unintended objects or causes optical errors, making it difficult to collect precise aerial photographic images. However, there was a problem that it was not possible to produce detailed and detailed digital maps because errors occurred in drawing images produced based on aerial photographic images. In addition, there is a problem in that economic and time loss occurs because aerial photography must be repeated through re-operation of the aircraft P when a section cannot be photographed as planned.

Therefore, it is necessary to develop a technology that prevents inertia due to speed control and turning of the aircraft from reaching the camera.

Prior art for solving the above problems is disclosed in Korean Registered Patent Publication No. 10-1551380 (2015. 09. 02.). This prior art maintains the current position during filming by providing a vertical gravity direction unit to offset the effect on the camera member when the aircraft body rotates (rotates) back and forth and left and right.

However, since the above-described prior art moves minutely and macroscopically rotates the camera member, improvement measures are required.

The foregoing technical configuration is a background technology for helping understanding of the present invention, and does not mean the prior art widely known in the technical field to which the present invention belongs.

Therefore, the technical problem to be achieved by the present invention is to minimize the change in the photographing angle of the aerial photographic camera when the aircraft posture is changed by flight speed adjustment, altitude adjustment, turning, etc. It is to provide a spatial image drawing system capable of realizing a video image according to a change in spatial information capable of capturing an intended position on the ground with a minimum of error.

The photographing device 100 is interlocked with the GNSS module 110, which operates and checks the current location information while communicating with the satellite A, and the altitude measuring device and level sensor mounted on the aircraft P, to determine the current location of the aircraft P and A location recognition module 120 for checking attitude information, etc., a camera member 10 mounted on the aircraft P and photographing the ground with the corresponding control word, and receiving and editing the aerial photographic image taken by the camera member 10 and GNSS The editing module 150 that checks the current location information or coordinate information from the module 110 and links the corresponding location information or coordinate information to the aerial image, and inputs the aerial image from the editing module 150 to the assigned area. It includes a memory 160 for storing and a communication module 170 for transmitting aerial photographic images stored in an allocated area of the memory.

The drawing device 200 is preferably installed on the ground, but may be installed inside the aircraft, and the communication module 210 receives the aerial photographed image transmitted from the photographing device 100, and the aerial image received by the communication module 210. The drawing module 220, which completes the drawing image that becomes the background of the digital map by converting the captured image into drawing processing, compares the status of the aerial photographed image received by the communication module 210 with the existing aerial photographic image stored Processing of transmitting a re-photographing signal to the photographing device 100 through the communication module 210 to check the state, extract the location information or coordinate information of the corresponding region where the defective aerial photographic image was captured due to an optical error, and re-photograph the image.

The location recognition module 120 records and stores the optimal shooting altitude and location information set and input by a photographer or operator in an allocated area, and communicates with the altimeter, speedometer, navigation device, etc. of the aircraft P while flying the aircraft P. Altitude, location information, etc. are checked in real time, and when the corresponding altitude, location, etc. are reached, the operation of the camera member 10 is controlled so that the corresponding area on the ground is continuously photographed.

In addition, the location recognition module 120 communicates with the level sensor provided in the aircraft P in real time to check the horizontal state of the aircraft P by operation, and when the horizontal state of the aircraft P reaches a stable range, the camera member The operation of (10) is controlled so that the ground is continuously photographed.

That is, even if the camera member 10 is not individually manipulated by the operator, the location recognition module 120 communicates with the altimeter and level sensor provided in the aircraft P to identify the optimal shooting time and locate the designated location on the ground. Since it is controlled to photograph aerially, there is an advantage of accurately securing a ground photographic image of a designated position using the camera member 10 installed in the aircraft P flying at high speed.

It is very natural that the data can be received in units of packets consisting of 1000 bytes of data, and the size of data in units of these packets can be increased or decreased as needed.

The drawing module 220 of the drawing device 200 is connected to the communication module 210 and receives the aerial photographic image edited by the editing module 150 and synthesized as an integrated drawing, which becomes the background of the digital map based on the aerial photographic image. Images are produced, and drawing image production proceeds with a common drawing work that can be generally known.

The processing module 230 checks information on a section that is missing from the synthesized aerial photographic image or for which re-shooting is requested, and transmits the location (coordinates) of the section to the photographing device 100, and the photographing device 100 retakes the image. It receives and analyzes the information required to be photographed and outputs corresponding location (coordinates) information.

The aircraft P moves to the location (coordinates) information for which re-photographing is required by the corresponding control signal, flies in the corresponding area while maintaining the same altitude, operating speed, etc., and the camera member (10) receiving the corresponding control signal ) proceeds with aerial photography and secures the aerial photographic image again.

The editing module 150 retakes the secured (obtained) re-photographed aerial photographic image as shown in the attached FIG. Since it is synthesized at the corresponding position of the image, a large-scale aerial photographic image without errors is finally completed.

The final synthetic large-scale aerial photographic image completed in this way is stored in the allocated area of the memory 160 with the corresponding time information included, and transmitted to the communication module 210 of the drawing device 200 through the communication module 170.
