Problems solved by technology
However, through the camera capture method, the moving object needs to be always within the recording range of the camera. If the moving object goes out of the recording range or is blocked, it is difficult to capture the correct three-dimensional shape, which leads to certain limitations in the camera capture method

The embodiment of the invention discloses a method and apparatus for capturing a three-dimensional form. The method comprises: a capturing device captures a motion track of a target object; the capturing device determines a stretching position for the planar motion track; the capturing device captures a stretching motion track of the target object at the stretching position; and the capturing device sends the planar motion track and the stretching motion track to a terminal device that is used for obtaining a three-dimensional form of the target object based on the planar motion track and thestretching motion track. According to the method and apparatus disclosed by the invention, the planar motion and stretching motion are performed by the target object, the target object has a 3D form,and then the planar motion track and the stretching motion track are captured to obtain the three-dimensional form of the target object to realize 3D inputting. Therefore, the limitation of capturinga three-dimensional mode by a camera is eliminated.
Description
technical field [0001] The invention relates to the technical field of virtual reality, in particular to a method and device for capturing a three-dimensional form. Background technique [0002] Three-dimensional shape capture technology is a technology used to measure the movement of moving objects in three-dimensional space. It records the movement of moving objects in digital form through related equipment, and then uses computers to process the movement data to obtain the moving objects. spatial coordinates. With the development of science and technology, three-dimensional shape capture technology has been widely used in animation, film, sports teaching and other fields. [0003] The current 3D shape capture technology mainly adopts the camera capture method. The camera placed in front of the moving object collects pictures of the three-dimensional shape of the object, and then compares the pictures at different times to determine the three-dimensional shape of the obj...
