Description

technical field [0001] The invention belongs to the technical field of unmanned aerial vehicles, and in particular relates to a city true three-dimensional automatic modeling system based on an airborne LiDAR and an inclined camera. Background technique [0002] 3D modeling is an important method for the application of aviation and satellite data, and it is a hot spot in the development of urbanization. The urban true 3D automatic modeling technology based on airborne LiDAR and tilting camera combines laser radar technology, photogrammetry technology, etc., and absorbs the advantages of manual production in traditional modeling methods. Traditional 3D modeling software has unparalleled advantages. The combination of LiDAR technology and oblique imaging technology can obtain a variety of aerial survey data products in one flight. The existing technology has the problems of low data collection efficiency, low data production efficiency, and low accuracy. Contents of the inv...
