Abstract

The invention discloses a gesture tracking method and device, and the method comprises the steps: enabling a wearable wristband to be worn at a wrist, enabling the surface of the wearable wristband tobe provided with optical pattern marking points, and enabling an inertial navigation sensor to be built in the wearable wristband; capturing the motion state of the optical pattern mark point in thespace in real time, obtaining an optical tracking image, and obtaining inertial navigation data of the wearable bracelet through the inertial navigation sensor; according to the optical tracking imageand the inertial navigation data, obtaining 4DoF information of the wearable bracelet through a computer vision technology, and the 4DoF information representing position movement information of thehand in the x-axis direction, the y-axis direction and the z-axis direction of the three-dimensional space and rotation information of the hand in the z-axis direction; and calculating other 22DoF information of the hand through the 4DoF information, thereby obtaining the position and posture information of the hand. According to the invention, the tracking precision of the hand position and posture can be improved.

Description

technical field [0001] The present invention relates to the technical field of gesture recognition, in particular to a gesture tracking method and device. Background technique [0002] At present, in the field of VR / AR / MR, there are various methods of gesture recognition. Usually, computer vision-based tracking and recognition technology or inertial sensor-based motion capture technology is used to solve the problem of gesture recognition. However, based on computer vision tracking and recognition technology and based on There are some problems with the motion capture technology of inertial sensors. [0003] Recognize and restore the opponent's posture, position, and finger joint posture based on computer vision tracking and recognition technology, usually through a tracking camera set up in the environment, or a tracking camera set on a VR head-mounted display device, and real-time tracking of the hand under the camera through image recognition technology The position, rot...
