Title:
CONTROL METHOD AND APPARATUS FOR 3D LASER SCANNER
Document Type and Number:
WIPO Patent Application WO/2024/077967
Kind Code:
A1
Abstract:
A control method and apparatus for a 3D laser scanner. The method comprises: according to an acquired instrument parameter of a 3D laser scanner and a resolution parameter corresponding to a horizontal rotation direction, determining a horizontal rotation control parameter corresponding to the 3D laser scanner; then, controlling a horizontal-rotation electric motor of the 3D laser scanner to sequentially rotate to each collection point; when the 3D laser scanner rotates to any collection point, controlling a vertical-rotation electric motor of the 3D laser scanner to execute a point cloud collection operation according to a preset collection frequency, so as to obtain all point cloud data in a vertical plane corresponding to the collection point, wherein after all the point cloud data in the vertical plane corresponding to the collection point is collected, the 3D laser scanner rotates to the next collection point of the collection point; and finally, executing a splicing operation on all the point cloud data. By using the control method for a 3D laser scanner, the difficulty of splicing processing of the point cloud data collected by the 3D laser scanner can be reduced, and the splicing efficiency of the point cloud data can be improved. Further disclosed are a control method for a 3D laser scanner, a control apparatus for a 3D laser scanner, and a computer storage medium.
