Motion capture system and method

Abstract

The invention relates to a motion capture system and method. The motion capture system comprises a positioning base station and tracked equipment, wherein the positioning base station comprises a first radio frequency transceiver and at least three ultrasonic emitters; the tracked equipment comprises a second radio frequency transceiver and at least one ultrasonic sensor; the positioning base station emits a data signal and an ultrasonic signal to the tracked equipment; after the traced equipment processes data, the spatial position, which is relative to the positioning base station, of each ultrasonic sensor is obtained; and the distribution information of all ultrasonic sensors on the tracked equipment is combined to determine the space position and the gesture, which are relative to the positioning base station, of the tracked equipment. When the motion capture system and method is implemented, spatial positioning can be finished only by one base station, no image recognition algorithms are required, and only time parameters are obtained. The motion capture system and method has the characteristics of being high in calculation speed, low in response time delay, low in power consumption, high in space position tracking accuracy and the like.

Description

technical field [0001] The present invention relates to the field of human-computer interaction, and more specifically, relates to a motion capture system and method. Background technique [0002] In recent years, virtual reality (VR) and other technologies have become hot areas for new products due to the gradual maturity of various technologies. Because these technologies can bring people a more dimensional sensory experience, human-computer interaction in these fields is also a hot spot in current research and development in the industry. The most important technology in this field is motion capture technology, through which the spatial position and spatial attitude of head-mounted displays and human-computer interaction devices can be obtained to achieve a close to real VR experience.

AI Technical Summary

Problems solved by technology

[0007] Disadvantages of the existing technology: Lighthouse requires high-speed rotating mechanical parts, which will generate large mechanical vibrations, which will cause positioning data to jitter, and there will be problems with mechanical wear and tear

SONY's binocular eye system has a small tracking range, slow response, and poor user experience
