Embodiment Construction

[0016] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0017] The hand motion capture method of the virtual reality system of this embodiment needs to be based on the following two requirements during implementation: 1. When detecting faces in the first few frames of the video, the user does not gesture; 2. In order to obtain a better segmentation effect , when the user makes a gesture, it is required to perform it in the area above the head, to avoid overlapping with the face, and to pause for a few seconds for ea...

Abstract

The invention discloses a hand action capturing method for a virtual reality system, and relates to the technical field of virtual reality analysis. The specific capturing process comprises the following steps: step 1, initializing; step 2, after a camera is started, when a reliable face is detected, establishing a skin color Gaussian model; step 3, when start=1 and gesture=-1 are detected in video stream, turning to step 4; step 4, performing differentiation on the current frame and a background image bgimg set in step 1 to obtain a differential binary image chafenimg, judging that the frame is a gesture stable frame, supposing gesture=1 and turning to step 5; and step 5, obtaining a hand action binary image. The hand action capturing method for the virtual reality system greatly improves the action capturing accuracy and speed, and meets the real-time capturing requirement.

Description

technical field [0001] The invention relates to the technical field of virtual reality analysis, in particular to a hand motion capture method for a virtual reality system. Background technique [0002] In the traditional hand motion capture method, the designer of the system designs the start motion of the gesture to divide the hand motion process into three stages: the beginning, stabilization, and end, such as making an L-shaped straight line. But the drawback of these methods is that the motion capture becomes cumbersome and unfriendly by requiring the user to perform an additional action before each gesture. Contents of the invention [0003] A hand motion capture method for a virtual reality system proposed by the present invention greatly improves the accuracy and speed of motion capture and meets the requirements of real-time capture. [0004] Technical scheme of the present invention is realized like this: [0005] A hand motion capture method for a virtual real...
