7. A vehicle based time variant geographical information acquisition system capable of receiving time variant geographical information from at least one remote monitoring host and providing the time variant geographical information to a vehicle driver or autonomous driving system, at least part of a plurality of image capturing apparatuses being installed at locations higher than the vehicle, each of the image capturing apparatuses aiming at a different road segment and having a capability to output information with precise time stamp, the at least one monitoring host receiving image data having the time stamp, the monitoring host including: a synchronization processor, a processing device and a database, wherein the synchronization processor operates on at least part of the image data, such that all of the time stamps have a same time axis reference point as a basis for differentiating a synchronization error from a transfer rate discrepancy, and the database stores the geographic information of all fixed objects in the road segment in at least part of a three-dimensional space, and the database also stores time variant location information of moving objects; such that when the vehicle drives into the road segment, the processing device determines relative position of the vehicle with respect to all of the fixed objects based on the image data with the time stamp, wherein the acquisition system includes:
a wireless communication unit for connecting the image capturing apparatuses and/or the monitoring host;
a timing unit used for operating conjunctively with the wireless communication unit to output a timing signal;
a memory module storing the geographic information corresponding to at least the moving objects in the three-dimensional space; and
a traffic scenario output interface for jointly displaying the geographic information and moving object information,
wherein the processing device from the monitoring host, based on time difference between the timing signal received from the timing unit and the time stamp, generates a new, time base corrected, predicted moving object location for the time variant geographical information acquisition system and transmits to the vehicle.
8. The vehicle based time variant geographical information acquisition system according to claim 7 , wherein the traffic scenario output interface further includes a warning device that sends a warning signal when the processing device determines that the time variant geographical information generates a change exceeding a prescribed range.
