SYSTEM FOR REVISING COORDINATE IN THE NUMERICAL MAP ACCORDING TO GPS RECEIVER

摘要

The present invention relates to a numerical information system which can correct numerical coordinates linked to a numerical map along the traffic line of a GPS receiver. The system immediately checks numerical coordinates of each point in a process of collecting collection images used as the background of a numerical map to correct the numerical coordinates of the corresponding numerical map on a real-time basis. The system includes an image collection device (200) and a numerical map correction device (100). The image collection device (200) includes: a collection module (210); an image check information DB (230); an image check module (220); an image adjusting module (260); an image transmitting module (250); a GPS coordinate DB (270); a GPS reception module (280); and a numerical coordinate correction module (290). The numerical map correction device (100) includes: a collection image processing module (110); a collection image DB (130); an object analysis module (120); an object variation check module (140); an image section search module (150); an image information editing module (170); a link information editing module (170′); and an image updating module (180).
