摘要
介绍在实时图像处理中的单摄像机监控系统运动目标检测与跟踪方法.针对运动目标的检测,首先进行帧间图像的匹配,接着计算图像间的误差,检测出运动区域,得到运动物体的大致轮廓.通过利用动态规划法改进的主动轮廓模型方法,提取运动目标轮廓.算法有较好的鲁棒性和抗噪声能力,速度也比较快.这种方法可以在轮渡站实时监控系统中得到应用.
A method for moving target detection and tracking in real time image processing system designed for a single camera surveillance system is described. First, for the detection of moving target, the image matching between the consecutive image frames is carried out, and the difference between consecutive image frames is calculated. Then the motion regions are detected and approximate contour of the moving target is obtained. Finally, by applying the dynamic programming method to enhance the conventional active contour model, the contour of the moving target is extracted. This approach provides robustness to noise and can be implemented with high speed. This method can be applied as a part of the real time surveillance system of a ferryboat station.
