摘要
针对倾斜摄影测量技术,分析进行三维重建时在纹理映射过程中存在的问题,当地区建筑物密集时,往往存在纹理遮挡情况。经过试验提出一种利用投影矩阵将三维模型纹理面映射到所要贴合的纹理影像中的方法,对密集建筑物的遮挡进行有效的处理。
This paper analyzed the problems in the automatic mapping of 3D model based on the oblique photography technology.It focused on the occlusion situation of dense building texture.A projection matrix is applied to map the 3D model texture surface which can make texture image to be fitted through testing.It effectively handled the problem of the texture occlusion on dense buildings.
