Embodiment Construction

[0061] In order to have a clearer understanding of the technical features, purposes and effects of the present invention, the specific implementation manners of the present invention will now be described in detail with reference to the accompanying drawings.

[0062] Such as figure 1 As shown, the optical three-dimensional motion capture method of the present invention includes:

[0063] 101. The infrared transmitting and receiving device emits infrared rays at a predetermined frequency in a preset space in a three-dimensional space;

[0064] 102. For the infrared rays currently emitted:

[0065] The handle moving in the three-dimensional space receives and reflects the current infrared rays to the infrared transmitting and receiving device; the direction in which the current infrared rays are incident on the handle is opposite to the direction in which the handle reflects the current infrared rays;

[0066] 103. The background system calculates the current position coordin...

Abstract

The invention relates to the field of dynamic capture systems in power training, and more particularly to an optical three-dimensional motion capture method and system. The method comprises the following steps that an infrared emitting and receiving device emits infrared rays at a predetermined frequency in a preset space in a three-dimensional space; for the currently emitted infrared ray, a handle that moves in the three-dimensional space receives and reflects the current infrared ray to the infrared emitting and receiving device; the direction that the current infrared ray is emitted to thehandle is opposite to the direction that the handle reflects the current infrared ray; a background system calculates the current position coordinates of the handle in the three-dimensional space according to the time point at which the infrared emitting and receiving device emits the current infrared ray and the time point at which the current infrared ray is received; and the background systemdetermines whether the handle is currently out of the preset range based on the current position coordinates, and issues an alarm if the handle is out of the preset range. The invention can ensure that the students are located in the virtual experiment environment in real time in the power training.

Description

technical field [0001] The invention relates to the field of motion capture systems in electric power training, more specifically, to an optical three-dimensional motion capture method and system. Background technique [0002] In electric power training, in order to ensure the safety of trainees during the training process to the greatest extent, virtual reality technology is often used to conduct practical training for trainees. In virtual reality technology, by constructing a virtual experimental environment, trainees can completely immerse themselves in the virtual training environment by wearing an immersive headset, and complete the training operation in the virtual environment through the operation of the handle. [0003] However, if the trainees go beyond the scope of the experimental environment during the operation, they cannot carry out the practical training operation. How to make the college real-time in the experimental environment during the training process h...
