摘　　要：针对车载智能监控的要求,设计一种嵌入式车体移动报警安全监控系统。系统以TMS320DM642芯片为核心,采用简化的Itti模型来提取监控画面的颜色和亮度特征,并检测和分割出感兴趣区域(Regions of Interest)。根据ROI质心相似度的变化来判断车辆状态。实验结果表明:该系统较为准确地检测和分割感兴趣区域,并能对其进行实时地监控;系统对车辆状态的判断和报警可靠性较高。In order to satisfy the requirements of VSM （Visual Surveillance and Monitoring） system, we design a vehicle movement detection based on an embedded video monitoring system. This monitoring system selects the TMS320DM642 as the core of system, using the simplified Itti visual saliency model to extract the color and luminous characteristics, which detect and segment the regions of interest（ROIs）. According to the change of the similarity of mass centers in ROIs, the monitoring system estimates the state of vehicle. The experimental results and their analysis show preliminarily that the monitoring system designed by us can detect and monitor the ROIs in real time and it has higher reliability in judgment and alarm.
