Problems solved by technology

[0009] In addition, when the user's hand makes a gesture, if the user's head also turns, there will be a large difference between the relative motion trajectory acquired by the built-in camera and the real motion trajectory of the hand, which will easily lead to erroneous motion. Gesture recognition, lower recognition rate

Abstract

The invention relates to virtual reality and augmented reality technologies and discloses a gesture identification method and apparatus based on a head-mounted visible device and the head-mounted visible device. The method comprises the steps of obtaining target object coordinate information of a first time point; obtaining a first included angle according to the target object coordinate information of the first time point; obtaining first angle information and obtaining a first posture angle according to the first angle information; obtaining target object coordinate information of a second time point; obtaining a second included angle according to the target object coordinate information of the second time point; obtaining second angle information and obtaining a second posture angle according to the second angle information; obtaining a target object angle of the second time point; and obtaining gesture information according to the target object angle and a preset gesture identification algorithm. By use of the method and apparatus as well as the head-mounted visible device, the problem of gesture identification errors caused by device rotation can be solved and the accuracy of gesture identification can be improved.

Description

technical field [0001] The present invention relates to virtual reality (Virtual Reality, VR) and augmented reality (Augmented Reality, AR) technologies, in particular to a gesture recognition method, device and head-mounted visual equipment. Background technique [0002] Virtual reality (Virtual Reality, VR) and augmented reality (Augmented Reality, AR) technologies are emerging multimedia technologies in recent years. Virtual reality technology is a computer simulation system that can create and experience a virtual world, and augmented reality technology is a technology that can superimpose and interact with virtual reality and the real world. In VR or AR scenarios, users usually wear a Head Mounted Display (HMD). The HMD device is composed of an integrated graphics system, optical system and posture tracking system, which can provide users with An interactive immersive experience. HMD usually uses the form of goggles or helmets to put the display screen close to the us...
