Method and system for capturing and rebuilding three-dimensional model

The invention provides a method for capturing and rebuilding a static three-dimensional model, which comprises the following steps of: acquiring an image of a moving object in an annular field; acquiring a visible shell model; acquiring a depth point cloud of each visual angle according to each visual image, the visible shell model and a preset constraint condition; and blending the depth point cloud of each visual angle to obtain the static three-dimensional model. The method of the invention can guarantee the precision and integrity of the rebuilt shape of the static three-dimensional model. In addition, the invention also provides a method for capturing and rebuilding a dynamic three-dimensional model.
