The extraction of multi-view matching points is one of the key elements in 3D reconstruction of multi-view image scene, because the extraction results will directly affect the accuracy of 3D reconstruction. With the conversion from the extraction of multi-view matching points to dynamic connectivity, a solution based on the Union Find algorithm was designed. The efficient tree structure with parent-link...
With the development of remote sensing technology, the source of data is getting more abundant and the resolution is becoming higher. Consequently, conventional change detection method can't meet the application requirements any more. In this paper, an object-oriented change detection method for multisource remote sensing images using multi-feature fusion was proposed to solve this problem. On the...
In recent years, registration between the remote sensing image and vector data has seen its increasing usage in photogrammetry-related applications. Many researchers select higher-level primitives instead of traditional control points since the disadvantages of point features. This paper has proposed an automatic registration approach based on line features, which is insensitive to rotational and...
High-level features especially free-form linear features contain more information comparing with point features, which are more useful to the latter disposal of image interpretation and surface reconstruction etc. An image matching method based on free-form linear features is proposed after the further research on description of free-form linear feature, selection of matching entity, and determination...
