Urban scene composition method and system based on street view image and vehicle laser fusion |
| abstract |
The invention belongs to the field of scene composition, and in particular relates to a method and system for urban scene composition based on fusion of street view images and vehicle-mounted lasers, and aims to solve the problem that the existing composition methods based on fusion of images and lasers are difficult to achieve efficient, robust and accurate. The problem of large-scale urban scene 3D map construction. The invention includes: respectively calibrating the initial value of the internal and external parameters of the street view camera and the initial value of the external parameters of the laser radar; constructing an optimization equation based on the image feature based on the scene image to be composed, constructing the optimization equation based on the point cloud feature based on the laser point cloud, and based on each An image of the scene to be composed and the corresponding laser point cloud of each station construct an optimization equation based on the corresponding image and laser; the optimization equation is integrated into a unified global optimization framework, and the parameters to be optimized are solved and iterated to obtain the three-dimensional composition of the scene to be composed. The invention realizes efficient, robust and accurate three-dimensional composition of large-scale urban scenes, and provides an idea for scene modeling integrating multi-source data. |
