For the purposes of real time detection and identification of objects, a real time image processing system in intelligent automobile with high frame frequency and large filed of view image was designed by using MPC5200 as its main operational processor. The hardware composition and the theory behind the real time digital image processing system, and the application of the image processing algorithm were all discussed in detail. On the basis of experiments and analysis of detection and identification algorithms for objects, a real time image processing software has been developed, and acquisition and real time digital processing of images was realized. In this way the detection and identification capacity for objects of the system met the real time demands of intelligent automobile application.
