摘　　要：针对弹道测量环境中大视场、大数据量、高速传输复杂的图像中多运动目标提取算法,设计了基于双DSP+FPGA的实时图像处理系统。提出了一种结合背景自适应更新与基于窗口的目标提取算法,通过背景自适应更新算法得到目标运动区域,再运用基于窗口的目标提取算法实时提取多运动目标的信息。实验证明,系统能准确实时地提取目标信息,满足弹道测量系统要求。For multiple moving objects extraction algorithm with a large field, a large amount of data and high-speed transmission of complex images in trajectory measurement environment, it designed real-time image processing system based on 2-DSP ＋ FPGA. It proposed a algorithm based on adaptive background updating and window-based target detection. Target movement area can be obtained by adaptive background updating algorithm. Then it used the window-based target detection algorithm to extract information of moving objects in real-time. Experiments show that the system can accurately extract target information in real time to meet the trajectory measurement system requirements.
