数字建筑模型生成大比例尺真正射影像方法

Large-scale true orthophoto generation based on digital building model

为解决城市大比例尺正射影像生成中出现的遮挡和阴影等问题,提出基于CSG数字建筑模型生成大比例尺真正射影像的方法,应用在美国丹佛城区的真正射影像生成的项目中,取得了令人满意的效果.

To sdve the problems such as incomplete orthorectification, occlusion and shadow due to the lack of proper 3 D model representation in traditional urban large - scale orthophoto, this paper presents a method of generating the true orthophoto based on 3 D digital building model. A test field located in downtown of Denver, Colorado has been used to test our methods. The experimental results demonstrat that the proposed method can effectively solve the problems mentioned above.
