[0002] In the field of manufacturing and product digitization, reverse engineering of parts has also become increasingly important and is widely used in part replication, defect analysis and other scenarios. Usually, optical scanning equipment is used to establish a three-dimensional model.

[0003] However, in practical applications, for complex structural parts, such as workpieces with fine decorative patterns on the surface, deep grooves / blind holes, distributed high inclined surfaces or chamfers, and functional structural features on the bottom surface, the existing image scanning technology still has some defects. First, the part surface pattern may be difficult for the scanning device to accurately capture the geometric profile due to texture reflection, pattern interference or insufficient color difference with the background; second, the deep grooves, high inclined surfaces and other areas are difficult to completely cover in a single clamping due to light obstruction or scanning angle limitations, often resulting in data voids or misalignment; third, when there are key structural features on the bottom surface of the part, the scanned part needs to be removed from the tooling and flipped for repositioning and clamping before being scanned again.

[0004] These problems not only consume time and effort, but also cause the registration accuracy of the two scanning data to decrease due to the second positioning error, ultimately affecting the integrity, accuracy of the three-dimensional model and the reliability of subsequent applications.
