Description

Leveling survey system to confirm the position of constructure having the datum point}

The present invention relates to a system for producing a digital map by synthesizing the GPS coordinates to the reference point of the set terrain, more specifically, the numerical map by measuring the change in the position of the ground structure in which the region and the national control point where the topography is changed in real time The numerical map of the GPS coordinate composition type according to the terrain reference point setting that minimizes the error by automatically restoring the reflected position error and the direction (orientation) error of the reference point generated by the original GS coordinate value. It relates to a manufacturing system.

In general, when making a digital map, etc., it is based on a reference point or a national reference point, and surveys the location information or coordinate information by the GPS of each point with respect to the feature of the selected region, and uses the surveyed location or coordinate information as data. Manage.

In addition, since the aerial map or satellite image (hereinafter, referred to as 'air aerial image'), which is a photorealistic image, is used in the digital map and reflects the GPS coordinate values surveyed at the corresponding point of the image, the image used in the digital map is assigned to the land number ( It can be used as an image for cadastral maps, guide maps, information maps, etc., which accurately displays the land, land, and boundaries.

Therefore, if the location and direction of the ground structure on which the surveying reference point is installed is changed due to terrain change, or if the reference point is incorrectly selected, an error may occur in the data of the entire digital map. It is necessary to have a system that can measure errors by GPS and quickly correct errors if there is an error in comparison with the original coordinate value or reference value information.

On the other hand, national land development projects and building projects such as private companies bring about frequent changes in the actual topography, and these changes lead to differences or errors in the surveyed information and images of existing digital maps. Periodic updates and corrections were needed.

However, in order to collect aerial photographs that are the background of digital maps, expensive aerial photographs were required, and after aerial photographs, the photographed aerial photographs must be inspected by national agencies such as the National Intelligence Service. There was a difficulty in going through the burdensome tasks procedurally and procedurally.

On the other hand, in the case of urban centers where high-rise buildings are concentrated, even when shooting the ground with a high resolution camera, a perfect plane cannot be photographed due to the complicated limitations of the ground and optical limitations such as the curvature and the shooting angle of the camera lens. In other words, after shooting, it is inevitable to edit the distorted aerial photography, and this work required a considerable amount of time.

As a result, the revision of digital maps using aerial photography has the advantage of providing a realistic background of digital maps, and it was not an advantage in terms of efficiency and accuracy. Information collection and geodetic surveying techniques have been required to produce these synthesized digital maps.

Patent registration No. 1115602 (2012.02.06.) As a conventional technique for improving this has been disclosed a "level surveying system for positioning the ground structure located in the three-dimensional reference point".

However, when the first and second panels and the first and second cushions are in contact with the installation surface in the patent registration No. 1115602, which is disclosed in the prior art, it is difficult to produce accurate digital maps, because measurement errors are generated when the first and second panels are not horizontal. Bars, in particular, lack the means to check the horizontal state, but the utilization was low despite the excellent performance.

In addition, according to the prior art, not only could not accurately measure various errors such as latitude error, longitude error, rotation error, altitude error that can occur on the ground structure, but also automatically recovers the correct ground structure even if the ground structure error is confirmed. There was a problem that was difficult to maintain the position of.

Hereinafter, a digital map production system of GPS coordinate composition type according to a terrain reference point setting according to the present invention will be described in detail with reference to the accompanying drawings.

1 is a view showing a schematic installation concept of the digital map production system of the GPS coordinate composition type according to the terrain reference point setting according to the present invention.

As can be seen in FIG. 1, the digital map production system 100 of the GPS coordinate composition type according to the terrain reference point setting according to the present invention includes a national reference point representative part indicating a national reference point and automatically corrects an error in the position of the national reference point representative part. Based on the location of the ground structure 200, the central control server 300 and the ground structure 200 is connected to the communication and the ground structure 200 to recover the surveying device 400 to accurately and accurately create a numerical map Include.

The national reference point is a reference point determined by the basic survey planned and conducted by the National Geographic Information Institute, and includes triangular points, level points, gravity points, and geomagnetic points. Specifically, the national triangular point is the point of the plane position, and the national level point is the point of the vertical position.

Specifically, the ground structure 200 has a national control point (national control point) is installed, and transmits the reference hardness and reference latitude values by wire or wireless by the GPS coordinate value of the national control point, and the GPS signal from the satellite Radio direction finding method that detects the positional movement of the national reference point by receiving analysis, and simultaneously rotates two antennas having an 8-type electric field to detect the direction of propagation of radio waves at two points with the same electric power. Receives the radio wave of the radio transmitter to detect the azimuth change of the national reference point, and recovers the error of the reference longitude and reference latitude due to the position movement and azimuth change.

The terrain on which the ground structure 200 is installed may be changed in hardness, latitude, altitude, direction, and inclination due to subsidence of the ground. The error as described above is detected.

In particular, the wireless azimuth measurement method is to rotate two antennas installed in the ground structure 200 at the same time to detect two points of the same received power of each radio wave from each antenna, and to analyze the two points detected by each antenna to arrive radio waves Detect or detect the direction to In this case, when an error is included in the detection value of two points, the error may be reduced by an arithmetic mean, and the accuracy may be improved because two antennas detect and analyze the direction of radio wave arrival. The plurality of ground structures 200 may detect a predetermined radio wave transmitted by the other party to detect how much the direction in which the other party or its own ground structure 200 is installed moves.

That is, when the second ground structure is installed in the north direction of the first ground structure, the first ground structure receives and analyzes radio waves transmitted from the second ground structure, and the direction is the direction when the first ground structure is installed. If different, it can be detected that the second ground structure is rotated or moved by a predetermined direction. There is also a way to interpret the contrary, but will be omitted for convenience of description.

The ground structure 200 may detect the errors of the longitude, latitude, altitude, direction, and inclination as described above, calculate the degree (size), and restore the national reference point circumference using the calculated result.

In addition, the ground structure 200 may generate a change detection signal in which the error value is recorded and transmit the generated change detection signal to the central control server 300.

The central control server 300 receives the change detection signal including the position movement and azimuth change of the national reference point from the ground structure 200, and updates the numerical map of the terrain on which the plurality of ground structures 200 are installed. In addition, a position recovery signal for recovering the error of the ground structure 200 is transmitted to the ground structure 200.

The central control server 300 may communicate with the plurality of ground structures 200 to receive a plurality of change detection signals to generate a digital map that reflects the topographical variations occurring in the wide terrain.

In addition, the position recovery signal, which is a command for correcting an error, may be transmitted to the ground structure 200 which has transmitted the change detection signal according to the set mode. In this case, the position recovery signal may be adjusted to include an error value smaller than the error value obtained from the change detection signal, which is considered when a specific change detection signal contains an error as a result of combining the plurality of change detection signals. This is to correct the error to a more accurate value by reflecting.
