Method and device for capturing movement based on framework and partial interpolation

Abstract

The invention provides a method and a device for capturing movement based on a framework and a partial interpolation. The method comprises the following steps of: reconstructing a first three-dimensional partial model and a second three-dimensional partial model and extracting a first framework of the first three-dimensional partial model and a second framework of the second three-dimensional partial model; interpolating the first framework and the second framework to obtain an intermediate framework between the first framework and the second framework; solving a deformation distance field between the first thee-dimensional partial model and the second three-dimensional partial model and interpolating a point cloud on the deformation distance field to form a three-dimensional model sequence through which the first three-dimensional partial model is transited to the second three-dimensional partial model; and filtering and reconstructing the point cloud of the three-dimensional model sequence to obtain a finally closed partial three-dimensional model sequence. The method for capturing the movement based on the framework and the partial interpolation of the embodiment of the invention has the advantages of quick capture and high precision. The device has the advantages of high precision and simple structure.

Description

technical field [0001] The invention relates to the field of multimedia technology, in particular to a motion capture method and device based on skeleton and face patch interpolation. Background technique [0002] Traditional motion capture techniques mainly include motion capture with a logo and motion capture without a logo. Motion capture with a logo will be greatly limited, and motion capture without a logo, which has developed rapidly in recent years, is in the ascendant. In the field of computer animation and three-dimensional modeling, the deformation technology of mesh is more and more widely used. Many mesh deformation techniques proposed in the past few decades can help artists achieve the effect of character animation. One of these technologies is 3D human motion capture, which has applications in games, movies, free-viewpoint video, motion analysis in medical diagnostics, and sports science. Ideally, one would expect to capture human motion with high definitio...

AI Technical Summary

Problems solved by technology

[0006] 1. The continuous motion capture method based on static 3D reconstruction of each frame alone has the disadvantage of high complexity of 3D reconstruction, and the complexity of reconstruction of each frame alone is quite large;

[0007] 2. The continuous motion capture method based on motion tracking has the advantage of generating 3D surfaces and 3D motion through time information, which is fast, but the disadvantage is that the accuracy of surface reconstruction is low
