本文针对现有技术中存在的问题提出一种对复杂背景下的多个移动物体进行目标快速识别与跟踪的复合算法。该算法中采用对连续图像进行差影计算来确定移动目标区域,从而能去除复杂背景干扰,可以明显提高目标识别的速度和准确率。该系统已被实验证明其有效性和实用性,可广泛应用于监测与识别系统,也可应用于无人监控,无人自主操作等各种领域。本文中所提到的算法现为国家某重点项目中的关键技术。 关键字:差影算法图像分割阈值 连通线 灰度值; 中图文分类号TP274 Abstract: In this paper, we mention a multiple arithmetic in allusion to the problem of existing technology which can recognize and track the target among many motive objects in complex background. This arithmetic can determinate the area of motive target through the difference calculating of consecutive image, which can get rid of the interference of complex background, then improve the speed and exactitude of recognizing target obviously. This system has been proved efficiency and utility by test, which can broadly apply not only in the system of inspection and recognition but also the realm of self-control and self-operation etc. Key words: different shadow arithmetic/image segmentation/threshold value/consecutive line/gray degree;
