| 摘 要： | 针对由于入射光的照射，目标阴影与背景有明显的区别，而被当做目标的问题进行了研究。分析了单幅图像的阴影检测方法，提出了序列图像阴影检测方法，建立了序列图像高度测量模型；采用相邻序列图像对应点匹配的约束条件，降低了匹配的复杂度；研究了序列图像的特征点匹配，获得平面目标的高度信息表示；基于阴影的二维表面属性，设计了利用空间三维信息中的高度信息检测阴影的算法，可以对任意形状的阴影进行检测。通过试验表明，该方法简单，适用面广，可以有效地检测阴影。

| Abstract: | For the light rays,shadows and background targets are significantly different.The shadow detection method based on single image is analyzed widely,a shadow detection method is proposed based on image sequence,and the space height measurement model is established.The matching constraints are researched on corresponding point of the sequence image,the complexity is reduced.The height information is calculated with the feature points matching of sequence image.The shadow detection algorithm by using the height... |
