The present invention provides a virtual reality feature point screening space positioning method, comprising the following steps: using preprocessed pictures to train the neural network; keeping the infrared point light source of the virtual reality helmet in an open state, and taking pictures with an infrared camera; preprocessing the pictures, Obtain a preprocessed image; input the obtained preprocessed image into a neuron to obtain the ID of the infrared point light source corresponding to each spot. Compared with the prior art, the present invention provides a method for determining the spot ID by introducing the neural network algorithm into the virtual reality space positioning method, which is accurate and efficient. By preprocessing the training images and test images, the diversification of pictures is prevented from affecting the recognition accuracy, and the diversified pictures are standardized, which greatly increases the success rate and accuracy of ID recognition.
Description
technical field [0001] The present invention relates to the field of virtual reality, and more specifically, relates to a spatial positioning method for screening virtual reality feature points. Background technique [0002] Spatial positioning generally adopts optical or ultrasonic mode for positioning and calculation, and the spatial position of the object to be measured is derived by establishing a model. A general virtual reality space positioning system uses infrared points and a light-sensing camera to determine the spatial position of an object. The infrared point is at the front end of the near-eye display device. physical coordinates. If the corresponding relationship between at least three light sources and projections is known, the spatial position of the helmet can be obtained by calling the PnP algorithm. The key to realizing this process is to determine the ID (Identity, serial number) of the light source corresponding to the projection. Due to the inaccurat...
