高速运动可视多目标精确检测研究

ACCURATE REGION DETECTION OF HIGH-SPEED MULTI-TARGET VISUAL SYSTEM

讨论了图像目标高速运动情况下邻帧差分运动检测法的严重缺陷。利用图像能量、高阶统计量理论,建立背景约束准则,运用块处理技术对序列场景进行快速背景重建,依靠重建背景进行运动区域检测。基于DSP C54X的平台测试表明:该文算法背景重建速度快,1秒左右即可完成无失真重建;动目标检测精度高、与目标速度无关。具有重要的理论及应用价值。

This paper discusses shortcomings of adjacent-frame difference. Based on the image energy and high order statistic (HOS) theory, background reconstruction constraint con-ditions are setup. Under the help of block- processing technology, background is reconstructed quickly. The DSP based platform tests indicate that the background can be recovered lossless in about one second, while moving regions estimations are not influenced by target speed.
