Device and method for real-time three-dimensionally sensing safe driving of vehicle having mixed multi-visual information

The invention discloses a device and a method for real-time three-dimensionally sensing safe driving of a vehicle having mixed multi-visual information. A video image collecting device is provided with six cameras; a main processor comprises a DSP subsystem and an APM subsystem; an SDRAM storage unit is connected with the main processor and an FPGA controller; the FPGA controller controls the collection of images around the vehicle, pre-treats the images and then stores in the SDRAM storage unit; the DSP subsystem reads images from the SDRAM storage unit, matches a frame image and rebuilds a three-dimensional scene; and the DSP subsystem synthesizes a predicted back track data and a rebuilt three-dimensional image and sends to a liquid crystal display in order to display. When a driver drives or backs a car, the phenomenon that a common backing device always has a blind area is completely avoided.
