Measurement techniques for complex surface based on a non-contact measuring machine

A non-contact measuring system is designed in this paper. In this system, a high-performance laser displacement senor and an additional turntable are integrated for acquiring the full dimensional data of complex surface. Due to the massive number of point clouds collected by the system, valid path planning methods are introduced in consideration of efficiency. As a result, the effectiveness of this system and measurement techniques for complex surface inspection are proved through various experiments.
