Method and device for scanning surface topography according to shape profile

Abstract

The invention provides a method and a device for scanning a surface topography according to a shape profile. The device comprises a mechanical arm, three-dimensional scanning equipment and a computer. The mechanical arm is connected with the three-dimensional scanning equipment, and the moving position direction and the moving speed of the three-dimensional scanning equipment are controlled by the mechanical arm; and the motion trail of the mechanical arm is controlled by the computer, and the three-dimensional scanning equipment is driven to move in space, so that the three-dimensional scanning equipment completely scans all three-dimensional point cloud data on the surface of a workpiece. According to the invention, manual mobile scanning is replaced, and the scanning efficiency and precision are improved.

Description

Technical field

[0001] The present invention relates to the field of three-dimensional scanning techniques, and in particular, to a method and apparatus for a respective profile scan surface morphology. Background technique

[0002] During the three-dimensional scanning process, the scanning method and the scan path are different due to the size of the different measurement workpieces, the surface shape and the measurement demand. Traditional handheld scanners or stent scanners require manual adjustment of the location of the measured or scanner, which is often done according to the personal experience of scanner. First, scan workers' personal capabilities limit their ability to handle different types of workpieces, and the difference in experience between different people will result in differences in scanning methods, and the secondary affects scanning efficiency or even scanning precision, second, users with large scan demand A large amount of time costs produced by artificial...
