Abstract： |
The present invention relates to automatic multiple view point laser scanning data registering method for large scale 3D scene. The method includes the following steps: obtaining the data of the measured scene by using laser range finder with Z-axis regulated to be perpendicular to ground and X-axis and Y-axis to be parallel to ground; scanning the measured scene to obtain the 3D data of each view point in the superposing rate of 10-20 %; extracting the structure and characteristic of the measured matter; calculating the virtual characteristic unit and constituting characteristic unit, coarsely registering, finely registering, overall registering and finally establishing registered model. The method of the present invention is widely applicable. |
