Change detection and update of 3D sparse map by merging geometry and appearance
Large-scale 3D sparse maps generated by Structure-from-Motion (SfM) from images play an important role in many applications, including visual localization, augmented reality, etc. In these scenarios, the timeliness of the map i.e., detecting changes in the map and performing partial updates, is cruc...
