Abstract

The invention provides a virtual-reality method for space location of feature points of a handle. The method includes the following steps that whether all infrared point light sources on the location handle are extinguished or not is confirmed, and if the infrared point light sources are not all extinguished, the infrared point light sources in a light-up state are extinguished; the first flashing infrared point light source set on the location handle flashes, and a processing unit records the location, on an image, of the lit-up infrared point light source according to a light spot on the image; according to the preset flashing sequence, the location handle sequentially commands the related infrared point light sources to flash, and correspondingly, the processing unit records location data of corresponding flashing points; according to the measured location data, spatial coordinates of the location handle are obtained through the processing unit. Compared with the prior art, by sequentially making the infrared point light sources flash, through cooperation with data comparison, the novel virtual-reality method for space location of the feature points of the handle is provided.

Description

technical field [0001] The invention relates to the field of virtual reality, and more specifically, to a spatial positioning method for feature points of a virtual reality handle. 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 positioning position of the helmet can be obtained by calling the PnP algorithm. One of the methods to realize this process is to determine the ID (Identity, serial number) of the light source corresponding to the projection. The current vi...
