| Abstract: |
| 3d laser scanner is a measurement equipment which can show 3d sharp and obtain point cloud of object. However most 3d laser scanner for mine exist these problem, such as: it is difficult to obtain point cloud attitude ,the composite accuracy between point cloud and mine design drawing is low. To solve these problems, this paper design double-axis tilt sensor and laser collimating system based on 3d laser scanner for mine we have developed. This hardware this paper proposes can obtain inclination angle and roll angle which will make point cloud parallel with horizontal plane and the composite accuracy between point cloud and mine design drawing is high. To verify the accuracy promotion effect, this paper choose two point cloud to have experiment,the experiment result show that point cloud attitude has been corrected and the composite accuracy is high, the accuracy promotion aim is attained. |
