Abstract

The invention discloses a light spot-light source matching method and device in a sight line tracking device. The sight line tracking device is composed of a first camera and a second camera. The method comprises: coordinates of a plurality of light sources, coordinates of all light spots in the first camera and coordinates of all light spots in the second camera are obtained, wherein the multiplelight sources are reflected by a cornea and then projection is carried out at the first camera and the second camera to obtain light spots; and traverse processing is carried out on the coordinates of the light sources and the coordinates of the light spots, and a matching relationship between the light sources and the light sources in the first camera and / or between the light sources and the light sources in the second camera are / is determined. Therefore, a technical problem of difficult light spot-light source matching in application of teh sight line tracking device in the prior art is solved.

Description

technical field [0001] The present invention relates to the field of eye-tracking equipment, in particular to a method and device for matching light spots and light sources in eye-tracking equipment. Background technique [0002] In the prior art, when using a gaze tracking device, based on the 3D approximate spherical model of the eyeball, the VR device estimates the line of sight of the long-distance device at the gaze point based on the pupil center coordinates and corneal reflection. When the VR device uses multiple cameras and multiple light sources , the line of sight can be estimated only by a single-point correction process. In actual use of the above-mentioned VR equipment, because the relative positions of the light source and the camera are different, the camera cannot capture the image at some positions, or the captured image is not good. In this case In this case, because the light source is often not specific, the matching of the light source spot cannot be com...
