Unmanned aerial vehicle (UAV) low-altitude remote sensing technology has recently been adopted in China. However, mapping accuracy and production processes of true digital orthophoto maps (TDOMs) generated by UAV images require further improvement. In this study, ground control points were distributed collected using a multi-rotor professional camera, at flight height 160 m above the designed sample distance (GSD) 0.016 m. A structure from motion (SfM), revised surface model (DSM) multi-view...
Automatic extracting road intersection points is essential for applications such as data registration between vector and remote sensing images, aircraft-assisted navigation. However, at a large scale, it difficult to quickly accurately extract due the problems caused by complex structures, geometric texture noise interference. In this context, taking OpenStreetMap (OSM) priori knowledge, we propose method automatic extraction of based on fuzzy inference. First, OSM are analyzed obtain...
Determining samples is considered to be a precondition in deep network training and learning, but at present, are usually created manually, which limits the application of networks. Therefore, this article proposes an OpenStreetMap (OSM) data-driven method for creating road-positive samples. First, based on OSM data, line segment orientation histogram (LSOH) model constructed determine local road direction. Secondly, homogeneity constraint rule texture feature statistical extract line, basis...
