摘　　要：实时图像跟踪处理能力是嵌入式系统中影响系统性能的核心因素。提出一种小型化低功耗的实时图像跟踪处理系统的设计方法,利用FPGA硬件化并行化处理的特性完成外部红外及白光相机图像采集控制及滤波预处理,利用DM648处理器实现了一种基于概率密度统计的目标跟踪算法实现对指定目标的持续跟踪,使用RS422串行总线接收主控端发送的控制指令并实时发送检测出的目标位置信息。系统采用多功能子模块叠层的架构保证系统具有较小的体积,并实现了50 f/s的图像处理速度,保证了图像跟踪的实时性。Real-time image tracking ability is the key factor in the embedded system. This paper presents a method of designing miniaturized low-power real-time image tracking processing system, based on the hardware parallel characteristics of FPGA, which can complete external infrared and white camera image acquisition and filtering. The method adopts DM648 processor to implement a tracking algorithm based on proba- bility density statistics to achieve continuous tracking of the target, receiving control instruction of master and sending the detected real-time position information of target through RS422 serial bus. The system has a small volume by the usage of multi-function structure, and realizes 50 f/s image processing speed and the real-time performance of image tracking.
