Technical Field

[0001] The present invention relates to the field related to scanning devices, and specifically, to an all-round three-dimensional scanner. Background Art

[0002] Three-dimensional scanning is a high-tech that integrates optics, mechanics, electronics, and computer technologies. It is mainly used to scan the spatial shape, structure, and color of an object to obtain the spatial coordinates of the object's surface. Its important significance lies in being able to convert the three-dimensional information of the physical object into digital signals that can be directly processed by a computer, providing a quite convenient and fast means for the digitalization of physical objects. Three-dimensional scanning technology can achieve non-contact measurement and has the advantages of high speed and high precision.

[0003] Most of the existing three-dimensional scanners lack a working support and require manual holding and operation, which is time-consuming and laborious. Moreover, it is impossible for humans to determine the distance, and the jitter during the scanning process will also affect the scanning accuracy. Therefore, in view of the above current situation, there is an urgent need to provide an all-round three-dimensional scanner to overcome the deficiencies in current practical applications.
