摘　　要：针对图像数据量大,运动目标检测算法复杂,而在实际应用中又要求实时对图像处理等特点,以DSP器件TMS320DM642为核心搭建了实时运动目标检测系统的硬件平台。为了有效检测出运动目标,提出一种将基于混合高斯模型的背景差分法和三帧差分法相结合的算法。实验表明,该系统能有效检测出运动目标,且满足实时性要求。Due to the large quantity of image data, the complexity of algorithm for moving objects cletecuon ana me real-time requirement in practical applications, a real-time moving objects detection system is designed which is constructed with the DSP chipset TMSC320DM642 as the core. An algorithm for moving objects detection based on Gaussian Mixture Model and Three-Frame Differencing is proposed to detect the moving objects. The experimental results indicate that the system can effectively detect moving objects and meet the real-time requirements.
