Abstract

It is a difficult problem to collect the information of accident in the detection system of traffic information. The paper states the principle of scanning the vehicles along the road with semiconductor laser .We can judge the moving state of the vehicles by distance image which is got by laser beam scan. The moving state will be abnormal in case the accident happens. This paper present the forming technology of scanning beam by semiconductor laser and the principle of software to dispose the distance image. This technology may also apply to other relative fields.
