3D image location surveillance system for the automotive rear-view

We have developed a new type of rear-view observation system. This system can rapidly detect the 3D position and size of obstacles or gutters behind the car and can warn of the danger of collision by anticipating the path the car will take. The system includes a laser projector, a CCD camera, a frame memory, a data processing unit, a steering angle sensor, and a warning display unit. In this paper, some design techniques required for use in an automotive environment are described. We also report the test results obtained under various cruising conditions.<
