Description

Geodetic surveying system that conducts geodetic surveying of terrain based on GIS and updates numerical information by checking displacement {Geodetic and Surveying System}

The present invention relates to a geodetic surveying system that performs geodetic surveying of terrain based on GS to improve the accuracy of the geospatial data collected from geospatial reference points in real time, and updates numerical information through displacement verification. .

In order to produce a digital map, it is necessary to collect image images of the ground for drawing, to draw an image based on the collected image image, and to synthesize coordinate information by matching GPS coordinates to a reference point set in the drawing image. Proceed.

However, since the image image is usually collected through aerial photography, the image image of the remote place is inevitably optically deformed. As a result, if GPS coordinates of a certain grid shape are applied to the video image as it is, an error between the edge point of the video image and the GPS coordinates will inevitably occur.

On the other hand, the drawing image based on the image image is shown in the polygonal outline of the building or various artificial structures (hereinafter referred to as "buildings") in the urban image along the shape and shape of the corresponding artificial structure of the image image. . That is, since the shape and size of the polygonal shape shown according to the shape and shape of the artificial structure in the image image, the optical limit is revealed, the accuracy was not reliable compared to the surrounding facilities such as roads. In addition, while the widely used digital map is used to simply confirm the user's current location or the location of a specific building based on the GPS coordinates, a realistic representation of the building is not required. It was not presented at all.

However, if the actual point of the GPS coordinates and the corresponding point of the GPS coordinates displayed on the numerical map do not coincide with the building image schematically shown, the user may experience great confusion and inconvenience in using the numerical map. In other words, if the GPS coordinates of the footpath where the user is located are indicated as being within a specific building image on the digital map, the user will inevitably confuse the current location, and the reliability of the digital map will inevitably fall.

Therefore, it is required that the shape of the building displayed on the digital map and its position are also shown in accordance with the GPS coordinates, which are reference points of the digital map. However, in the downtown area, many radio signals are flooded and mutual interference between various signals is frequent, so that the communication between the GPS system and the satellite is not smooth. As a result, in this measurement environment, the temporary GPS measurement was impossible to accurately measure the GPS coordinates of the corresponding point, and the digital map modified and supplemented based on the measured information does not sufficiently solve the conventional problem.

In addition, when looking at the coordinate collecting device in the conventional Patent No. 10-0933932, there is a risk that the volume is large, inconvenient to carry, and damaged because there are many protruding parts. In particular, there is a disadvantage in that it takes a long time to install and collect, there is a problem inconvenient to use to download and move the data one by one to the storage unit.

The present invention has been made to solve the above problems of the prior art, it is possible to complete and update a more accurate and reliable digital map by drawing the building image displayed on the digital map to match the actual terrain and GPS coordinates It is possible to increase the accuracy by checking the collected data about geodetic information in real time compared to the GS reference point, to receive the GPS coordinate-related data wirelessly, and to easily carry by minimizing the rapid removal and size of the coordinate collection device The purpose is to provide a geodetic surveying system that performs geodetic surveying of terrain based on YES and updates numerical information by checking displacement.
