Problems solved by technology
However, although the above two scanning methods can solve the problem of partial projection blind spots, when the scanned object is a dynamic object, such as a human face, the obtained 3D image still has large distortion and low quality

Embodiment Construction
[0023] Specific embodiments of the present invention will be described in further detail below based on the accompanying drawings. It should be understood that the specific embodiments described here are only examples, and are not intended to limit the protection scope of the present invention.
[0024] see figure 1 , the embodiment of the present invention provides a three-dimensional scanning system 100 for scanning a dynamic object, for acquiring a three-dimensional image of a dynamic object 200 . The so-called dynamic object system refers to an object whose three-dimensional image or model changes with time. For example, the three-dimensional image of a human face will be different at different time points due to different expressions.
[0025] The three-dimensional scanning system 100 includes a first projection device 10, a first photosensitive device 20, a second projection device 30, a second photosensitive device 40 and a control system 50.
[0026] The first proje...

The invention relates to a three dimension scanning system for scanning a dynamic object. The three dimension scanning system for scanning the dynamic object is used for obtaining a three-dimensional image of the dynamic object and comprises a first projector, a first sensitization device, a second projector, a second sensitization device and a control system. The first projector is used for projecting first monochromatic light to the dynamic object. The first sensitization device corresponds to the first projector and can only collect the first monochromatic light reflected by the dynamic object, and a first image is formed. The second projector is used for projecting second monochromatic light to the dynamic object. The second sensitization device corresponds to the second projector and can only collect the second monochromatic light reflected by the dynamic object, and a second image is formed. Due to the control system, the first projector and the second projector are controlled to simultaneously project the first monochromatic light and the second monochromatic light to the dynamic object, the first image and the second image are calculated and fitted, and therefore a three-dimensional image of the dynamic object is obtained. In addition, provided is a three dimension scanning method for scanning the dynamic object.
Description
technical field [0001] The invention relates to a three-dimensional scanning system and a scanning method thereof, in particular to a three-dimensional scanning system capable of acquiring a three-dimensional image of a dynamic object with high quality and low distortion and a scanning method thereof. Background technique [0002] Three-dimensional scanning is a high-tech integrating optical, mechanical, electrical and computer technologies. It is mainly used to scan the spatial shape, structure and color of the scanned object to obtain the spatial coordinates of the object's surface. Its significance lies in the ability to convert the three-dimensional information of the actual object into a digital signal that can be directly processed by the computer, providing a very convenient and quick means for the digitization of the object. The 3D scanner (3D Scanner) prepared by 3D scanning technology, as a fast stereoscopic measurement device, has become an important tool for 3D m...
