MOBILE MAPPING SYSTEM FOR PRODUCING TOPOGRAPHICAL MAP DATA WITH MOVEMENT MULTI SENSOR MOUDLE

摘要

The present invention provides a mobile multi-surveying sensor module that acquires and synchronizes the position of an object to be observed, such as road terrain, as an image, and then increases the precision of a CCD camera and a laser scanner while driving a target structure to generate 3D terrain data. It relates to a mobile mapping system that generates three-dimensional terrain data through. More specifically, the present invention is a mobile multi-survey sensor module consisting of a GPS receiver, an INS, a CCD (Change Coupled Device) camera, a laser scanner, a multiplex, an MMS control unit, and a wireless Internet module. Sensor Moudle) is configured, it is possible to construct an integrated system by synchronizing the CCD camera, GPS receiver, and INS configured on the top of the vehicle, and to update it in compatibility with the existing terrain data, and by adding the ground reference point to the post-processing process. The accuracy of GPS/INS can be improved, and 3D terrain data converted into 3D coordinates of an object can be generated in real time using the measured image coordinates while driving in a vehicle. Its purpose is to provide a mobile mapping system through a mobile multi-survey sensor module capable of transmitting updated terrain data.
