摘 要:
在对建筑物墙面纹理进行恢复时,经常会碰到影像上纹理被树木遮挡的情况。一方面影响了纹理的完整性,另一方面对影像上建筑物纹理进行处理时,由于树的存在会产生噪声,有可能会对处理的结果产生干扰,应该将树的遮挡去除。对近景序列影像上树木遮挡的自动去除问题进行了研究,提出综合考虑影像重叠度和影像上房屋纹理所占百分比进行树木遮挡影像自动剔除的方法,进而依据色调和平行直线信息去除影像上树木遮挡,实验证明是行之有效的。[著者文摘]

The Automatic Removal of Tree Occlusion on Building Facade Texture
KANG Zhi-zhong （College of Geo-info Science and Eng. , SUST, Qingdao, Shandong 266510, China）
Abstract:
To recover the texture of building facade, the occlusion of trees is inevitably becoming a problem to be solved. As a result, the whole facade texture is difficult to acquire, furthermore, the existence of trees may disturb the processing of the texture from close-ranged imagery, i.e. it may disturb the extraction of lines from buildings. Therefore, the area occluded by trees should be automatically distinguished and removed. An algorithm of occlusion removal employed information of hue and lines is introduced and proved to be applicable.[著者文摘]
