Problems solved by technology

When the eye-tracking device is used by different people, the curvature of the iris and sclera of the human eye is different, and the angle of the human eye when looking in various directions is also different. At this time, the distribution of the light spots may be poor, and the preset single reasoning cannot satisfy All the spot distribution or light source distribution, resulting in poor matching effect between the spot and the light source
Another method of shooting the distribution of light spots through two cameras increases the cost and complexity of the device, and reduces the processing power and calculation speed of the eye-tracking device

Abstract

The invention discloses a light spot and light source matching method and device, equipment and a storage medium. The method comprises the following steps: determining light source coordinates of each light source and light spot coordinates of each light spot; matching the light spots with different light sources to obtain a plurality of groups of matching sequences; the light spots and the light sources in each matching sequence are in one-to-one correspondence; determining a matching score of each group of matching sequences according to each light source coordinate and each light spot coordinate; and determining the matching sequence with the highest matching score as a target matching sequence. According to the invention, the problems of small application range and poor matching effect caused by different human eye iris sclera curvatures and different human eye watching angles when light spot light source coordinates are deduced through a preset comparison mode and a preset formula in an existing light spot light source matching method are solved; the light spots of any number and different angles can be matched with the light sources of different distribution forms, and the light spot light source matching accuracy and universality are improved.

Description

technical field [0001] The embodiments of the present invention relate to the field of electronic technology, and in particular, to a method, device, equipment and storage medium for matching a light spot and a light source. Background technique [0002] During the use of the eye-tracking device, whether the light spot and the light source are successfully matched has a great impact on the eye-tracking accuracy. [0003] The existing spot light source matching method is to compare the coordinates through a preset comparison method after obtaining the coordinates of the spot, light source, and pupil center, or to deduce the coordinates through a preset formula. Then it is very important whether the preset reasoning can adapt to various forms of light source distribution and the distribution of light spots reflected on the eyeball. When the eye-tracking device is used by different people, the curvature of the iris and sclera of the human eye is different, and the angles of th...
