Abstract

The invention discloses a method and device for determining parameters in sight tracking equipment. The method comprises the following steps of: obtaining a to-be-detected image and a feature matrix of the to-be-detected image; processing the to-be-detected image on the basis of a preset model so as to obtain a first vector and a second vector of the to-be-detected image; and determining parameters of the to-be-detected image on the basis of the first vector and the second vector, wherein the parameters of the to-be-detected image comprises at least one of positions of light spots in the to-be-detected image and sight directions of eyes in the to-be-detected image. According to the method and device, the technical problem that the sight estimation algorithms and light spot prediction algorithm of sight tracking equipment in the prior art are complex in calculation is solved.

Description

technical field [0001] The present invention relates to the field of gaze tracking, in particular to a method and device for determining parameters in a gaze tracking device. Background technique [0002] In the process of using the existing gaze tracking device, it is mainly based on the 3D approximate spherical model of the eyeball, so as to estimate the gaze point of the long-distance device according to the coordinates of the pupil center of the eyeball and corneal reflection. However, when using multiple cameras and multiple light sources, only a single point correction can complete the line of sight estimation and the matching process of the light source and the spot. However, in practical applications, the theoretical calculation of the above method for estimating the line of sight is relatively complicated, and, because the light source is not specific, the camera at some positions may not capture the image or the captured image may not be correct. As a result, the ...
