摘要
利用高速球形摄像机和图像采集与处理单元,设计了一种运动目标检测与实时跟踪系统.首先用混合高斯背景模型实现对运动目标所在区域的识别,由此确定运动区域的质心,并以该质心为中心初始化跟踪窗口;然后在目标区域内提取颜色特征,通过CamShift算法计算目标的精确位置并调整搜索窗口大小.系统利用这些信息,通过串口控制高速球形摄像机的运动,使目标始终位于摄像头的视场范围内,并尽可能位于视场中央,以实现对运动目标的快速准确的实时跟踪.在艾立克一体化球形摄像机上进行了实验,验证了本系统的有效性.
A system for automatic detecting and real-tracking the moving target has been designed based on high speed spherical camera （HSSC）. Firstly, the region having the moving target is identified by mixture model of Gausslan, and the centroid of this region is determined as the center of initializing window for tracking. Then the color feature of target in the region is extracted and the CamShift algorithm is used to calculate the exact location of the target and adjust the size of search window. Finally the information about the target location is transmitted by serial communication to control the HSSC in order to track the target to ensure it being inside of scene all along. The experiment is performed with HSSC E588/G3-HP and verifies the validity of the system.
