Abstract

The invention provides a gesture recognition method, device and system. The method comprises the steps of acquiring coordinate information of the fingertip and the third finger joint in a world spacecoordinate system by inertial sensors arranged at the fingertip and the third finger joint; obtaining an established finger joint bending angle solving equation set of the fingertip relative to a third finger joint coordinate system according to a preset approximate solution formula; and sending bending angles Theta 1, Theta 2 and Theta 3 obtained by calculation to a preset three-dimensional modelto generate the corresponding gesture. By means of a mathematical model of solving the bending angle backwards through the coordinate information, accurate bending angle information can be efficiently calculated and obtained, the number of inertial sensors used in the traditional gesture recognition method is reduced, the structure of a gesture recognition product, for example, the structure of adata glove is simplified, and at the same time, the portability and the operability of the data glove are greatly improved due to the reduction of the number of the inertial sensors, and the manufacturing difficulty and the cost of the data glove are reduced, and the user experience is better.

Description

technical field [0001] The invention belongs to the technical field of motion capture, and in particular relates to a gesture recognition method, device and system. Background technique [0002] Inertial motion capture technology is a motion capture technology based on inertial sensor motion capture equipment. By using the nine-axis inertial sensor of accelerometer, gyroscope and magnetometer, the attitude and relative position of each node are measured to capture the movement changes of the hand, but , due to the relatively low measurement accuracy of inertial sensors, a large number of inertial sensors are required for position calibration and compensation when performing complex hand motion capture, that is, inertial sensors need to be set at each node or joint of the finger to obtain accurate In this way, due to the large number of inertial sensors used, the manufacturing of data gloves is difficult, the cost is high, and the portability of wearing convenience is not hig...
