Description

Geodetic data system dedicated to the leveling instrument for collecting geographic information {GEODETIC SURVEY DATA SYSTEM FOR COLLECTING GEOGRAPHIC INTELLIGENCE USING ONLY FOR CONNECTING LEVEL MEASURING UNIT}

The present invention relates to a geodetic data system dedicated to the leveling instrument connection for collecting geographic information, and more particularly, it is easy to check the change of geographic information according to the natural and artificial terrain changes, and maximize the installation stability on the slope. Access the leveling instrument for collecting geographic information to improve the accuracy of the digital map by improving the accuracy of the digital map by updating the digital map produced based on the existing data, and checking and updating the error of the data according to the geographical information and the topographical information. It relates to a geodetic data system.

In applications such as geographic information system (GIS), flight simulation, military training and operational simulation, three-dimensional computer games, virtual reality, etc., terrain data measured using satellite photographs, aerial photographs, ground surveys, etc. Requires skills to represent the terrain in the area.

There are two general ways to represent the terrain.

First, there is a method of expressing the terrain as a set of contour lines connecting points representing the same altitude, and second, there is a three-dimensional DEM that displays the altitude of the grid points divided into finely uniform intervals.

In addition, in order to visualize the topographical surface of a region in three dimensions, a topographical surface construction technique for constructing the topographical surface of the region in close approximation to reality is also required.

In recent years, high resolution satellite images have been widely used in a variety of applications, including general mapping, photogrammetry, and geographic information system (GIS) data acquisition and visualization.

Since satellite images are distorted by the tilt of the satellite sensors and topographical variations on their surface, the images must be orthorectified in order to be able to be used in each application. The satellite image represents an image distortion phenomenon in which the image pixel points are not placed at the correct position due to various factors such as the attitude of the satellite and the degree of tilt of the camera when the image is taken. Considering all the factors that cause such distortion, the process of removing the distortion of the image so that the position of each pixel point in the image coincides with the position on the topographical map by geometrically reconstructing the environment as it was at the time of image capturing is called orthodontic correction. .

Orthorectification of satellite images is usually obtained by resampling pixels of satellite images using rational polynomial coefficients (RPCs). However, when the glass polynomial coefficients are not given, the optimal glass polynomial coefficients are indirectly computed using the optimization technique of the glass polynomial coefficients using ground control points (GCPs) and DEMs that are well distributed on the surface.

In addition, large-scale mapping applications have increased the importance and amount of modeling of terrain as well as models of buildings and other objects on the ground surface. Examples of such modeling include the Digital Surface Model (DSM) for the DEM. And Digital Terrain Model (DTM) are used.

However, since a digital map is completed by applying geographic information on a map image completed by a general drawing process, the actual terrain may change from the existing geographic information with natural / artificial changes over time.

In addition, when the digital map is initially produced, errors (eg, height errors) may be generated due to incorrect measurement, and thus the topographical information and geographic information may be different.

Therefore, the information possessed by the digital map needs to be updated periodically, and its confirmation has also been required for errors generated during production.

However, in the related art, no technical means for updating the digital map and checking the error have been proposed, and thus, the digital map has not been easily adjusted.

As a result, there was an unreasonable necessity to create a new digital map in order to update the digital map.
