A review of non-contact 3D reconstruction techniques

3D reconstruction is a technology to obtain 3D information of objects. It is a research hotspot in the field of computer vision and computer graphics. It is widely used in the fields of robot vision navigation, industrial manufacturing, medicine, and so on. At present, there are many methods of 3D reconstruction technology. The external environment, equipment, and object geometry of 3D reconstruction will have a certain impact on the accuracy and stability of the 3D reconstruction effect. By analyzing the principle, the non-contact 3D reconstruction technologies such as time-of-flight method, grating reconstruction, structured light reconstruction, monocular, binocular, and multi eye reconstruction of passive 3D reconstruction, and 3D reconstruction based on depth learning are analyzed.
