Circumstance monitoring device of a vehicle

摘要

A circumstance monitoring device of a vehicle comprises an image capture means for shooting an image of surroundings of the vehicle and for inputting image information; a vehicle information detection means comprising a dead-reckoning system for consecutively detecting a moving state of the vehicle; a three-dimensional environment information constructing means for constructing three-dimensional environment information of the surroundings of the vehicle based on the image shot by the image capture means; a storing means for storing at least one of the image information and the three-dimensional environment information; a displaying image creation means for creating a displaying image based on the three-dimensional environment information. <??>Thanks to the present circumstance monitoring device it is possible to memorize in a 3D model, parts of the scene already observed from several shots taken while the vehicle is moving. Using this virtual 3D model, the scene can be observed by the driver from any virtual point of view at any instant. <IMAGE>
