Description

Technical Field

[0001] The utility model relates to the technical field of three-dimensional scanning detection, in particular to a multi-channel three-dimensional scanning detection device. Background Art

[0002] As an advanced digital measurement method, 3D scanning technology has been widely used in various fields in recent years. With the growing demand for high-precision and high-efficiency 3D measurement in industries such as industrial manufacturing, aerospace, medical health, and cultural heritage protection, 3D scanning technology is also constantly innovating and developing. As an important branch of 3D scanning technology, multi-channel 3D scanning detection devices are gradually favored by the market for their unique advantages.

[0003] On the production line of an automobile manufacturing plant, automobile parts (such as engine cylinder heads, transmission housings, etc.) on the conveyor belt need to be scanned quickly and accurately in three dimensions to ensure that their size, shape, and surface quality meet the design requirements. These parts often have complex geometric shapes and precise assembly requirements. Traditional measurement methods require setting up multiple scanning devices in different directions, which is costly and energy-intensive. Slight changes in the surface of the object, sudden changes in angles, or uncertainty in the motion trajectory may cause the scanning path to not match the actual needs, thereby affecting the continuity and accuracy of the scan.

[0004] In view of this, this application is hereby filed. Utility Model Content
