Description

Map image drawing system for image updating with GIS

The present invention relates to an image updating drawing system according to new data based on GS, and more particularly, to calculate arithmetic average of a plurality of coordinate information precisely measured in a method including GS, and to update the drawing image. The present invention relates to a video update drawing system based on GIS-based new data that records dimensional image images in a linked state and provides them by searching.

The drawing image maps the topographic map of the ground using the ground image taken from the aircraft and reflects coordinate information, location information, and numerical information (hereinafter referred to as “coordinate information”) by numerical values at each point of the map. A digital map is generally produced by a correction drawing method, an analysis drawing method, and a digital drawing method.

Partial changes may occur from time to time due to large-scale construction, and the numerical values of the changed parts should be updated from time to time.

Drawing images using aerial photographs are expensive because they are taken by aircraft, and all the photographed images must be fully inspected by the relevant national institutions such as the National Intelligence Service. It is common to take.

In addition, some of the features are changed from time to time due to construction, development, etc. It is a reality that it is economically very burdensome to repeat expensive aerial photography every time.

On the other hand, due to optical limitations such as uneven curvature of the camera lens and difference in shooting angles, areas where high-rise buildings are crowded and crowded areas are difficult to shoot in a completely flat plane even when using an aircraft. Bends).

It is necessary to synthesize a plurality of aerial photographs into one integrated image, to correct the distortion of the mapped drawing image, and to accurately update the coordinate information of each part.

As a conventional technique for making a digital map from aerial photographs, there is a "digital map production system and method using GPS and INS" according to Patent Registration No. 10-0558367 (2006. 02. 28.).

1 is a functional configuration diagram of a digital map production system using GPS information according to an embodiment of the prior art.

Hereinafter, with reference to the accompanying drawings it is a configuration that includes a GPS sensor 100, the NPS sensor 110, the camera 120, the control means 130.

The GPS sensor 100 and the INS sensor 110 are respectively installed in the aircraft to measure the movement path information of the aircraft, respectively, and outputs to the control means 130.

On the other hand, the camera 120 is installed on the aircraft and photographed the ground for map production and outputs to the control means.

The control unit 130 adds time information to the photographic image captured by the camera 120.

On the other hand, the control means 130 performs a process of complementary complementary to the position information input from the GPS sensor 100 and the position information input from the IS sensor 110 at the time when the photographic image is taken by the Kalman filtering method.

The control means 130 completes the numerical map by applying the position information calculated by the Kalman filtering method as coordinate information about the center position of the photographic image.

The camera 120 for photographing the image is recorded at 50-60 frames per second and the image is overlapped by about 60%, so that the distortion of the camera lens and distortion caused by the photographing angle are compensated to the maximum, thereby increasing the reliability of the image.

However, since the prior art photographs the ground using an aircraft, there is still a problem that the fundamental curvature of the lens and the shooting angle still cannot be solved.

In addition, the prior art has a problem that can not accurately update to reflect the changed coordinate information according to the change of the topography (terrain) in a specific area of the ground.

On the other hand, the prior art still has a problem that does not solve the problem of costly, time-consuming and difficult procedures to provide a new image of the changed ground feature.

Therefore, there is a need to develop a technology for solving the curvature and angle angle of the aerial shooting lens, updating the coordinate information of the region where the feature is changed, easily and quickly, and providing a new image of the changed region, at a low cost and time.

In order to solve the problems and necessity of the prior art as described above, the present invention precisely measures the coordinate information changed by the development, construction, etc. of the feature, reflects it on the corresponding part of the digital map, and photographs the 3D image of the site together.

The rotating frame 2330 is formed so that the first rotating hole 2320 in which the first rotating shaft 2310 is inserted in the rotating state is aligned in a straight line, and forms an inner diameter larger than the outer diameter of the cylindrical portion 2110. Shape the frame.

Since the pivot frame 2330 is installed in the first pivotal hole 2320 in the first pivoting hole 2320 in an inserted state, the pivot frame 2330 is installed at an upper portion of the coordinate detector 2100 to rotate the coordinate detector 2100 in a 180 degree range. Can be.

The second pivot 2340 is protruded in both directions on an outer circumferential surface of the pivot frame 2330 on a straight line perpendicular to the straight line formed by the first pivot hole 2320 and horizontally perpendicular to each other.

The second pivot 2340 may rotate the pivot frame 2330 in another 180 degree range.

That is, the coordinate detection unit 2100 rotates in one direction by 180 degrees in one direction by the first pivot shaft 2310, and rotates in a 180 degree range in another direction at right angles by the second pivot shaft 2340. It is possible to rotate freely within the range.

The second pivoting hole 2350 is formed at an upper portion of the supporting part 2360 and is pivotally coupled by inserting the second pivoting shaft 1210 in a pivoting state.

The mobile communication system 5000 provides an LBS service at the request of the printed circuit board 2200.

The image drawing server 6000 is connected to the PCB 2200 and the GS server 6500 through a communication path formed by the communication network 4000.

The image drawing server 6000 transmits a command signal for controlling the control unit 2220 of the printed circuit board unit 2200, and converts the averaged coordinate information and H.264 (H.264) into a format of the data frame 7000. A video signal compressed and encrypted in a .264) manner.

The image drawing server 6000 corresponds to the current position or the movement path of the vehicle measurement unit 2000 that is accurately measured by decoding the received average coordinate information, and thus the moving direction, the moving speed, the latitude value, the longitude value, and the sea level value. Extract the coordinate information included.

Also, the image drawing server 6000 decodes the received image signal and extracts the image signal photographed in three dimensions.

On the other hand, the image drawing server 6000 reads the numerical map by the Geographic Information System (GIS) from the GS server 6500.

The GS server 6500 records and manages a numerical map by the GS, and provides corresponding information of the searched area.

GIS inputs location information (coordinate information) and property information about various natural objects (mountains, rivers, lands, etc.) and artificial objects (buildings, roads, railways, etc.) existing on the earth's surface, underground, and ground spaces. It is a numerical map made to efficiently support various planning, decision making and industrial activities.

The image drawing server 6000 decodes the corresponding coordinate information value of the numerical map read from the GS server 6500 in real time to update the value of the extracted coordinate information, and simultaneously connects the video signals and reconnects the GS server ( 6500).

Therefore, the GIS digital map updated and recorded on the GAS server 6500 is updated with at least 9 times the precision of coordinate information, and records the 3D video signal together and outputs the data by searching.

In the above configuration, the three GPS antennas 2270, 2280, and 2290 are horizontally moved to the vehicle while the feature is changed, while receiving and analyzing the same GPS signal without error from the GPS satellite 3000. Arithmetic mean is calculated to calculate the first coordinate information having improved accuracy by three times or more.

In addition, since the NS processor 2230 uses the second coordinate information measured by the inertial navigation, the coordinate information can be accurately measured even in an area where the GPS signal cannot be received, such as a tunnel.

In addition, since the LBS processing unit 2240 calculates the third coordinate information received from the mobile communication system 5000 by the first coordinate information, the second coordinate information, and the arithmetic mean, it updates the coordinate information with higher precision by a total of 9 times or more. This has the advantage of increasing the reliability of digital maps.

In addition, since each coordinate information is recorded in a designated area of the data frame 7000 and transmitted in an encrypted state, transmission errors do not occur and recovery is easy.

In addition, while measuring the coordinate information, the surrounding feature is taken as a three-dimensional image signal and recorded and provided in a state linked to the corresponding coordinate information has the advantage of increasing the preference.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is evident that many alternatives, modifications and variations will be apparent to those skilled in the art.
