| Abstract: | Three-dimensional laser scanner overcomes the traditional measurement method using single point, and it can easily replicate objects and establish three-dimensional models. The authors introduce the structure of 3D laser scanner and its principle of realization, and build a three-dimensional laser scanning platform using the self-purchased laser radar, camera, electronic control platform and other components. The hardware control of laser radar, camera and electronic control platform is realized by serial communication, and the 3D laser scanning point cloud generation and image acquisition are completed, and the accuracy of the generated point cloud is corrected. At last, multi scan images are spliced based on feature points, and the matching fusion of the scanning point cloud and image is successfully achieved, in which the precision of point cloud and the effect of image fusion are better. |
