Abstrait:

3D-modeling of buildings in OpenStreetMap project (OSM) is a new trend, and the level of detail (LOD) for most 3D building models still present - LOD1 without taking into account the modeling of building roofs. In addition, there are many defects and shortcomings existing in 3D building models that need to be corrected and adjusted. In this article, we propose to use the available data LiDAR (Technology of using light in the form of a pulsed laser to measure distances to objects on Earth) with free aerial photography image to build 3D models of buildings to eliminate existing defects and shortcomings and to obtain fairly accurate 3D building models for OSM. To demonstrate one of the shortcomings of 3D OSM models, we reviewed the 3D model of the building of the St. Petersburg National Research University of Information Technologies, Mechanics and Optics (ITMO) in OpenStreetMap, and, having corrected this deficiency, obtained a revised 3D model. Applying the proposed method of using LiDAR data with aerial photography, we selected a territory in the city of Christchurch in New Zealand, where there are available LiDAR data, downloaded LiDAR data point clouds from the Open Topography site and built fairly accurate 3D models of buildings that exist in this area of study with their roofs using the Global Mapper software. Accordingly, we received good and complete 3D- building models with a level of detail LOD2.
