This paper introduces a novel multi-layer line grouping method for perceptually building extraction from stereo aerial images. Nowadays, perceptual grouping algorithm for line features obtained from images has been widely investigated, but there are little attentions to be paid to building height information of the line segments applied in existing literature of edge grouping field. In order to enhance...
In this paper, we proposed a novel texture-mapping method for buildings using remote sensing images and digital surface model. For generating better 3D map, boring manually or semi-automatic texture-mapping of buildings is always needed. However, only with remote sensing images and digital surface model, it is difficult to generate ‘sides’ of buildings, and corresponding relation between triangular...
This paper presents a feature guided multi-window area-based matching method for urban remote sensing stereo pairs. The method achieves the goal that producing dense disparity maps for urban remote sensing stereo pairs. The proposed method can be divided into four stages: feature-based matching, edge support region extraction, area-based matching and post-processing. The point feature matching is...
Digital Surface Models (DSMs) generated from airborne laser-scanning or stereo satellite images provide a very useful source of information for building orientation estimation. However, due to the high complexity of the building structure, it is hardly to get the details of the building boundary information. In this paper, a new orientation estimation method is proposed, which merge the edge information...
