A new solution to the high-quality 3D reverse modeling problem of complex surfaces for fine workpieces is presented using a laser line-scanning sensor. Due to registration errors, measurement errors, deformations, etc., a fast and accurate method is important in machine vision measurement. This paper builds a convenient and economic multi-view stereo (MVS) measurement system based on a linear stage and a rotary stage to reconstruct the measured object surface completely and accurately. In the proposed technique, the linear stage is used to generate the trigger signal and synchronize the laser sensor scanning; the rotary stage is used to rotate the object and obtain multi-view point cloud data, and then the multi-view point cloud data are registered and integrated into a 3D model. The measurement results show a measurement accuracy of 0.075 mm for a 360° reconstruction in 34 s, and some evaluation experiments were carried out to demonstrate the validity and practicability of the proposed technique.

Reverse engineering is a new modern product design technology, which is suitable for designing complex curve and surface, has been becoming a practical and widely-available engineering tool in panel design of automotive, motorcycle and electric vehicle. This paper first expatiates on the basic theory of structured light measurement system, registration algorithm of multi-view point cloud data and the basic principle of curve and surface reverse design, and then gives an application example in the 3D design of electric vehicle front panel.
