Abstract

In order to solve the problem that there was big gap between result of extracting the building based on shadow and real building number owing to the big area of trees shadow, combining with building DSM data, a new method of building extraction from remote sensing image with colors that based on DSM and shadow was presented. It eliminated the influence of vegetation information by setting the vegetation segmentation threshold.It extracted the shadow area of building from image partitioned by the mean-shift algorithm.It got the NDSM image that included actual height by processing of DSM.Then it extracted the building again and optimized extraction. The result indicated that this method improved precision to some extent than only according to the shadow for building extraction and the experiment configuration was more regular and closer to real surface features.
