【Abstract】 The design and realization of an embedded video traffic surveillance system are presented. As the front part of intelligent transportation system, it is utilized to collect the traffic information of highway and monitor the status of road, The system uses ARM920T S3C2410A processor for control and TMS320C6211 DSP chip for algorithm process to form a dual -core system, and uses MPEG media encoder chip GO7007 to compress image. The paper particularly describes the hardware design of the system and Linux devices driver. Through real test, the accurate ratio of vehicles count is over 90% , the error ratio of speed test is below 5% and the transmit speed is 25 f/ s for QCIF image.更多还原
