Description

An image processing system that integrates and manages real-time image information data collected by drones {IMAGE PROCESSING SYSTEM FOR MANAGING REAL-TIME IMAGE INFORMATION DATA COLLECTED BY DRONE}

The present invention relates to an image processing system, and more particularly, to an image processing system for integrated management of real-time image information data collected by a drone.

The orthographic image is secured by correcting the deviation of the aerial photograph, which is the central projection, and correcting it in the form of orthographic projection like a map. Here, the deviation correction is the operation of correcting the inclination (slope) and scale (photographing magnification), etc., which are generated when shooting with a camera.

For these orthographic images, a ground image is obtained by orthographic projection, and an orthographic image without errors is extracted by using a digital elevation model (DEM) on the secured orthographic photographic image, and the colors of the orthogonal image are corrected and aggregated and error-free. It is built through a series of processes that are arranged through calibration and final quality inspection.

Orthographic aerial projection to secure video image (orthogonal image) secures the projected photographic image by overlapping 60% or more in the vertical direction and at least 30% in the horizontal direction by the aircraft route.

Numerical elevation model is essential in the process of orthographic photographic image production in order to correct the geometric distortion of the aerially projected photographic image through central projection. Then, the extracted photographic image of the orthographic image is subjected to a color correction process for correcting color, contrast, etc., and an image aggregation process for synthesizing the image in a sheet unit with the neighboring image.

The final orthographic map image is completed through image processing that includes color correction and image aggregation of the orthographic image obtained by orthogonal co-projection, It is common to synthesize coordinate information (location information).

However, aerial photography using an aircraft to secure video images is costly and time consuming, and it is very cumbersome because it is necessary to use a separate camera device on the ground to directly photograph the terrain features that are difficult to accurately identify with aerial photography. .

In other words, aerial photography using an aircraft has a problem in that it is difficult to quickly reflect changes in topographical features because the waiting time from one shooting to the next shooting is long and expensive, so it is not possible to take frequent pictures periodically.

In addition, since the aircraft passes through the filming point at high speed, it is impossible to stay in the filming area, and if necessary, the aircraft must be turned and photographed again, and thus there are problems such as an increase in cost and an increase in time.

Based on the principle that it can be defined, it should be interpreted as meaning and concept consistent with the technical idea of the present invention.

1 is a diagram showing the overall configuration of an image processing system for integrated management of real-time image information data collected by a drone according to an embodiment of the present invention.

As shown, the image processing system for integrated management of real-time image information data collected by the drone according to the present invention includes a base station 100 , a photographing drone 300 , and a management server 200 .

The base station 100 receives the position values from the GPS satellites, calculates them, outputs the GPS correction values, and wirelessly transmits the output GPS correction values.

Specifically, the base station 100 arranges the GPS antenna 111 to calculate the GPS correction value by mutually calculating the current position value received from the GPS receiver 110 and the GPS receiver receiving the position value from the GPS satellite and the specified absolute value. It includes a DGPS transmitter 120 for wirelessly transmitting a GPS correction value from the base controller 130 by disposing a base controller 130 that outputs and a differential GPS (DGPS) antenna 1210 .

And the base station 100 transmits the GPS correction value (position value) calculated through the base control unit 130 to the DGPS transmitter 120, and the DGPS antenna 121 connected to the DGPS transmitter 120. Shooting to be described later It is transmitted wirelessly to the drone 300 .

The photographing drone 300 wirelessly communicates with the base station 100, calculates the GPS correction value received from the base station, calculates the coordinates of the measurement point, and photographs the area according to the coordinates.

The management server 200 is installed in a remote location, receives the video image taken by the drone 300, extracts a difference from the pre-stored video image, and then performs a function of generating an edited image.

The management server 200 includes an image storage module 210 , an image receiving module 220 , a coordinate synthesis module 230 , a magnification editing module 240 , and an image correction module 250 .

2 is an exemplary diagram schematically illustrating a video image captured by a photographing drone according to an embodiment of the present invention.

The image storage module 210 stores an existing image image in advance, and the image receiving module 220 wirelessly receives the image image photographed from the photographing drone 300 . That is, the image storage module 210 stores the image image before the topography change occurs, and the image receiving module 220 may receive the image image captured after the topography change occurs.

The coordinate synthesis module 230 synthesizes GPS coordinates with the video image taken from the drone 300 . The coordinate synthesis module 230 includes a shape setting module 231 , a reference point setting module 232 , a comparison point setting module 233 , and a coordinate confirmation module 234 .

The shape setting module 231 is to edit the video image received from the video receiving module 220 to limit the range, and to synthesize the video image captured by the drone 300 with other video images. conforming to form and specification.

For example, as shown in FIG. 2 , the image image received by the image receiving module 220 is cut into a rectangular image, and the horizontal and vertical lengths of the rectangular image are set to meet the standard.

The reference point setting module 232 is to take the center of the image P1 cut by the shape setting module 231 as the reference point (C). At this time, it is preferable that the corresponding point of the image image P1 taken as the reference point C does not change according to the topographical features.

The comparison point setting module 233 sets an arbitrary point relatively comparable to the reference point C as the comparison point R.

This comparison point R becomes a comparison value for determining the sameness between the real geography, which is the object of the video image P1, and the video image P1. The setting of the comparison point R has no special restrictions, so it can be variously selected within the range of the video image P1 with the reference point C as the center.

The coordinate confirmation module 234 checks the actual GPS coordinates of the reference point C, and prepares for synthesizing the GPS coordinates centered on the reference point C in the video image P1 based on this.

At this time, since the standard of the GPS coordinates must match the standard of the video image (P1), check the GPS coordinates of the comparison point (R), and the 'real distance' between the reference point (C) and the comparison point (R) and the video image (P1) Check the 'image distance' between the reference point (C) and the comparison point (R) on the image, respectively. The coordinate check module 234 calculates the ratio of the 'real distance' and the 'image distance' checked in this way, and reduces or enlarges the GPS coordinates according to the scale.

The coordinate check module 234 synthesizes the reduced or enlarged GPS coordinates in the video image P1 so that the GPS coordinates are applied to the entire video image P1 in addition to the reference point C and the comparison point R.

3 is an exemplary diagram schematically illustrating a process of reducing and editing a video image using a magnification editing module according to an embodiment of the present invention.

Figure 3 (a) is a video image (P1) taken through a shooting drone and a video image (P1 ') edited with the magnification of the video image (P1), Figure 3 (b) is a pre-stored existing video image ( P2) is shown.

As shown, the magnification editing module 240 edits the video image P1 to which the GPS coordinates are input at the same magnification as the previously stored video image P2, and reduces or enlarges the video image P1 itself. In this way, it can be accurately compared with the existing video image P2.

The magnification editing module 240 is configured to match the magnifications of the video images P1, P1' and P2 having various magnifications, the corresponding reference point (C) and the comparison point (R) of the video images P1, P1', P2. Check the distance (D) between them, and adjust the magnification of the video images (P1, P1', P2) so that these distances (D) match. In this case, the selected reference point C and the comparison point R may be the same point in the newly captured video image P1 and the previously stored video image P2.

The image correction module 250 reads the image image P1' edited at the same magnification in comparison with the existing image image P2 stored in advance, the processed image module 251, the comparison detection module 252, and and an edited image module 253 .

The processed image module 251 generates a processed image file by extracting a layer from the image image received through the image receiving module 220 and processed through the coordinate synthesis module 230 and the magnification editing module 240 .

In other words, the processed image module 251 extracts the layers of buildings, roads, altitudes, fences, and inland water systems required for correction, and warps them to create a processed image with a resolution that can be decoded. do.

The comparison detection module 252 detects a difference by comparing the existing image and the processed image stored in the image storage module 210 . The comparison detection module 252 compares the generated processed image with the existing video image, detects differences in position and shape, and classifies each processed image as an object to be read or an object to be read.

For example, as in FIG. 3 , when a number of buildings are newly added (different in shape) in the upper right corner based on the crossroads near the reference point C, the processed image may be classified as an object to be read.

The edited image module 253 analyzes the processed image classified as an object to be read by the comparison detection module 252, and when it is read that there is a change in the feature, the extracted layer of the processed image is added to the existing video image. Creates and saves a new edited image file.

In this way, by comparing the received video image with the pre-stored video image, the video image with differences can be replaced with the latest video image. It is possible to quickly provide the changed video image according to the

The rotating unit 400 performs a function of horizontally rotating the camera 340 coupled thereto.

The rotation control unit 500 may communicate with the rotation unit 400 and control the rotation angle of the rotation unit 400 so that the user can rotate the camera 340 at a desired angle.

That is, when the user operates the rotation control unit 500 , the rotation unit 400 connected thereto by wire or wirelessly rotates, and accordingly, the camera 340 can be adjusted to a desired angle.

The rotating case 510 is formed in a hexahedral shape as a whole, and may be disposed at a position adjacent to the rotating unit 400 or may be disposed at a remote location for convenient use by a user.

On the other hand, since the rotating case 510 may be disposed in a remote place, it is necessary to have a certain degree of durability. Specifically, the rotating case 510 includes a coating layer on its surface, wherein the coating layer contains 26.7 to 50.3 parts by weight of a zirconium content and 38.3 to 69.7 parts by weight of a niobium content based on 100 parts by weight of a rigid aluminum material, Scandium Or it may be formed by spraying an alloy powder containing 1.3 to 2.3 parts by weight of yttrium.
