Problems solved by technology

The advantage of this solution is that it is easy to use, cheap, high precision, and free from space constraints; but the disadvantage is that due to the influence of the environmental magnetic field, a large number of sensors are required to achieve accurate finger capture, and it is impossible to determine the position of the hand in space. Unable to realize the interaction of multiple hand movements

Abstract

The invention discloses a method and a device for calibrating multiple sensors on a pair of motion capture gloves, and the pair of motion capture gloves. The multiple sensors comprise an optical tracker and a first inertia measurement unit. The method comprises the following steps that: independently collecting the position information of the optical tracker under an optical coordinate system andthe gesture information of the first inertia measurement unit under an inertia coordinate system under a plurality of motions of the motion capture gloves; and according to the position information ofthe optical tracker under the optical coordinate system and the gesture information of the first inertia measurement unit under the inertia coordinate system under the plurality of motions, calibrating the optical tracker and the first inertia measurement unit.

Description

technical field [0001] The present application relates to the technical field of motion capture, in particular to a method and device for calibrating multiple sensors on a motion capture glove and the motion capture glove. Background technique [0002] Virtual reality (Virtual Reality, VR) technology is a computer simulation technology that can create and experience a virtual world. It has been more and more widely used in various industries and people's real life, and has broad development prospects. [0003] Motion capture is very important in virtual reality technology. The collection of motion data in the real world requires motion capture. Motion capture usually needs to be done with equipment, and motion capture gloves are the most commonly used motion capture equipment. [0004] Before using motion capture gloves for motion capture, the gloves need to be calibrated to ensure the correctness and accuracy of the collected data, improve the accuracy of hand posture res...
