Abstract

The invention provides a gesture tracking method and device. The method comprises the steps: executing initialization operation on a three-dimensional hand model; performing projection operation on the three-dimensional hand model by utilizing the internal and external parameter sets of the binocular shooting component to obtain two digital images; performing distance transformation operation on the two digital images to obtain a second left-eye nearest neighbor index map and a second right-eye nearest neighbor index map; constructing a nonlinear optimization equation containing a main energyitem and a constraint energy item, and solving the nonlinear optimization equation to obtain a parameter adjustment step length of the hand three-dimensional model; and adjusting the three-dimensionalhand model based on the parameter adjustment step length. Due to the fact that the binocular shooting component can shoot the hand from different angles, the self-shielding area in one digital imagecan be displayed in the other digital image, and the problem of hand self-shielding can be solved through cooperation of the two digital images.

Description

technical field [0001] The present application relates to the technical field of image processing, in particular to a gesture tracking method and device. Background technique [0002] With the substantial improvement of mixed reality technology, mixed reality technology has been paid attention to and used in many fields. In the process of realizing the interaction between reality and virtual reality, the most direct way is through gesture interaction. Gesture tracking is an important technology to solve gesture changes. [0003] The commonly used gesture tracking technology is to combine depth sensors and monocular shooting components, specifically: use monocular shooting equipment to capture two-dimensional images including hands, and use depth sensors to perform depth map gesture tracking solutions on two-dimensional images, so as to obtain The 2D image is used to calculate the 3D hand pose data. [0004] Since a monocular shooting device is used to shoot two-dimensional ...
