Abstract

The invention discloses a hand geometric motion reconstruction method and device based on a multi-voxel block. The method comprises a step of acquiring a human hand skeleton according to depth data ofa first frame and initializing the multi-voxel block, a step of performing motion estimation on a hand through a reconstructed hand model in the multi-voxel block to obtain new depth data, and a stepof fusing the new depth data into the multi-voxel block and updating a geometric model of the hand so as to simultaneously reconstruct the motion and geometric models of the hand. According to the method, the geometric model and motion information of the human hand can be reconstructed at the same time, the dependence on a parametric model in a traditional human hand motion reconstruction processis avoided, the robustness of the human hand reconstruction technology is enhanced and the application range of the human hand reconstruction technology is expanded, and the development of the humanhand reconstruction technology is promoted.

Description

technical field [0001] The invention relates to the technical fields of computer vision and graphics, in particular to a multi-voxel block-based hand geometric motion reconstruction method and device. Background technique [0002] Hand reconstruction is an important and fundamental problem in the field of computer graphics, and has a wide range of applications in the fields of virtual / augmented reality, human-computer interaction and artificial intelligence. For example, in the field of virtual reality, by reconstructing the geometry and motion of the human hand, the interaction between the human hand and the virtual object can be realized to enhance the sense of reality of the person in the virtual environment; in the field of human-computer interaction, the gesture recognition technology that has emerged in recent years has passed Track the movement of the hand and map the specific movement of the hand to the instruction set, which can replace the traditional keyboard and ...
