METHOD OF UPDATING GIS NUMERICAL MAP OF SURVEYING INFORMATION STRUCTURAL FACILITIES ALONG ROAD BY USING VEHICLE WITH GPS RECEIVER, LASER MEASURING INSTRUMENT AND CAMERA

摘要

The present invention is a GPS receiver, a road around the facilities survey information using a vehicle equipped with a laser surveying instruments and cameras as the value of on the GIS map update method, more specifically, while driving a vehicle equipped with a GPS receiver, a laser instrument, camera coordinates, and image acquiring positions of various facilities and the surrounding road, immediately corrected by the information in real-time to a method for updating a GIS digital map. The method can be applied very easily to acquire the digital terrain data, such as localized facilities around the road, it is possible to obtain a high accuracy by using a laser with a straight, particularly digital map, such as the city that changes day by day and to allow for quick and accurate updates. In addition, the present invention is a kind, size, shape and the like by a variety of various facilities are adjacent to record the image of the facilities, even if a series arrangement with a number of facilities near by storing the position coordinates can be distinguished from each other.
