ELECTRONIC MAP OF VIRTUAL INFORMATION SYSTEM USING PLANE AERIAL PHOTOGRAPHING AND GPS MEASUREMENT INFORMATION MERGING

摘要

PURPOSE: A system for confirming numerical information of electronic map using plane aerial photographing and GPS measurement information merging is provided to protect a lens unit exposed to the outside from external force. CONSTITUTION: A system for confirming numerical information of electronic map using plane aerial photographing and GPS measurement information merging comprises a base station(200), a total station(300), and a numeric information conversion processing unit. The base station comprises a GPS receiver(210), a controller(220), and a DGPS transmitter(230). The total station includes a main body(310), a measure system part, a DGPS receiver(330), a GPS receiver(340), a touch panel, a controller(360), and a data transmitter(370). The measure system part precisely measures the angle and the distance of a measured point. The DGPS receiver receives GPS correcting value from the DGPS transmitter of the base station. The GPS receiver receives the present position value from a satellite(100). The numeric information conversion processing unit has an image database(410), a data receiver(420), a data processing part(430), and a drawn image output part(440). The image database stores aerial photographing images. The data processing part receives the aerial photographing images and the angle and distance and position coordinates of the measured point produces drawn image.
