Basic introduction of bim UAV tilt photography technology;
Bim UAV tilt photography technology is a 3D modeling software developed based on tilt photography technology. Based on the continuous aerial images collected by unmanned aerial vehicles, a realistic three-dimensional scene model can be generated quickly, accurately and automatically by using the graphic computing unit GPU. By analyzing the three-dimensional model of the real scene, we can get the three-dimensional coordinates, visual field, slope and current building of the real site. Therefore, tilt photography modeling software is widely used in many fields, such as mountain survey planning, urban construction planning, ancient building protection and so on.
By carrying a multi-lens camera on the same flight platform, images can be collected simultaneously from vertical, oblique and other angles during the flight, and more complete and accurate ground feature information can be obtained. In the process of modeling and surface texture, vertical images contain the top information of buildings, and oblique images can provide perspective of the side of ground objects. The combination of the two can meet the needs of building surface texture and model generation.
