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
[0016] 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.
[0017] 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.
[0018] The 3D 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 .
[0019] The first projection devic...

The invention relates to a three-dimensional scanning system for scanning a dynamic object, which is used to obtain a three-dimensional image of a dynamic object, which includes a first projection device, which is used to project a first monochromatic light to the dynamic object. A first photosensitive device corresponding to the first projection device, the first photosensitive device can and can only collect the first monochromatic light reflected from the dynamic object to form the first image. A second projection device is used for projecting a second monochromatic light to the dynamic object. A second photosensitive device corresponding to the second projection device, the second photosensitive device can and can only collect the second monochromatic light reflected from the dynamic object to form the second image. A control system, the control system controls the first projection device and the second projection device to simultaneously project the first monochromatic light and the second monochromatic light to the dynamic object, and calculate the first image and the second image Fitting, so as to obtain the three-dimensional image of the dynamic object. In addition, the invention also provides a scanning method of a three-dimensional scanner.
Description
technical field [0001] The invention relates to a three-dimensional scanner and a scanning method thereof, in particular to a three-dimensional scanner 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 (3DScanner) prepared by using 3D scanning technology is a fast stereo measuring device, because of its fast measurement speed, high precision, no...
