摘要:

设计了基于ADSP-BF561的视频跟踪系统,通过控制摄像机姿态实现对运动目标的自动识别和跟踪。系统采用三帧间差分法与图像分割相结合进行目标识别,利用卡尔曼滤波算法进行目标定位,辅以云台运动控制算法完成目标跟踪。经室内测试,该系统能对运动目标进行有效识别与跟踪,且具有一定的实时性及稳定性。

Abstract:

A video tracking system based on ADSP-BF561 is designed.By controlling the posture of camera,the system can automatically detect and track the moving target in the monitoring scene.By combining the algorithm of inter-frame difference of three frames with image segmentation,target recognition has been realized.Target location is obtained with Kalman-filter,and target tracking is achieved by PTZ control algorithm.Some tests have been done in indoor environment,which show that it can recognize and track the moving object accurately with a good real-time performance and robustness.

Key words: target detection;video tracking;ADSP-BF561;PTZ control
