Abstract

The invention discloses a motion collecting and feedback method and system based on stereoscopic vision. The method comprises the following steps that the space position of an infrared light source in an attachment position in a front space is collected, the space position is mapped into a virtual space, and the position and direction of a virtual object are controlled; when the virtual object interacts with a virtual environment, a wireless control attachment device vibrates and simulates the feedback feeling of force. The motion collecting and feedback method and system based on stereoscopic vision have the advantages that positioning is rapid and accurate, and operation is stable; the hardware is quite low in cost, simple in structure and quite small in size; force feedback is achieved and can largely improve the sense of reality of interaction behaviors, and user experience is improved; the reality function is improved, and the man-machine interaction modes are increased.

Description

technical field [0001] The invention relates to a method and system for motion collection and feedback based on stereo vision, and belongs to the technical field of virtual reality and augmented reality. Background technique [0002] Hand movements are collected and used as input signals for computer control, so that hand movements can be reproduced in a virtual environment for human-computer interaction. This type of human-computer interaction usually has the following implementation methods: [0003] 1. Laser scanning: The laser scans the range in front, the sensor collects the reflected light in each direction, calculates the distance, and obtains the depth information of each point in front to form a depth map. If the hand is placed in front of the sensor, the outline of the hand can be displayed on the depth map; and if the laser is used to continuously scan the front range, the spatial position, motion trajectory and posture of the hand can be continuously collected b...
