Embodiment 1

[0061] figure 1 It is a flow chart of a test method for an eye tracking device provided in Embodiment 1 of the present invention. This embodiment is applicable to the test of an eye tracking device. The method can be executed by a test device of an eye tracking device. The testing device of the device may be implemented by software and / or hardware, and the testing device of the eye tracking device may be configured on a computing device, specifically including the following steps:

[0062] Step 110, obtaining the vertical distance between the user's eyes and the screen, and determining it as the first distance.

[0063] Wherein, the screen may be a virtual screen or a projection screen of a VR device, or any display screen with a display function.

[0064] Optionally, the vertical distance between the user's eyes and the screen may be obtained by using methods such as distance sensor distance measurement, electromagnetic wave distance measurement, or image algorithm distance ...

Embodiment 2

[0089] figure 2 It is a flow chart of a test method for an eye tracking device provided by Embodiment 2 of the present invention. The technical solution of this embodiment is further refined on the basis of the above-mentioned technical solution, specifically including the following steps:

[0090] Step 210: Obtain the vertical distance between the user's eyes and the screen, and determine it as the first distance.

[0091] Step 220: Generate a plurality of calculated gaze points when acquiring the user's gaze target gaze point, wherein the target gaze point is a point displayed on the screen that the user gazes at, and the computed gaze point is the user's gaze point calculated according to the gaze tracking technology.

[0092] The specific implementation of the above steps is the same as steps 110-120, and will not be repeated here.

[0093] Step 230, acquiring the gaze angle of the user, and comparing the gaze angle with the set maximum viewing angle.

[0094] Wherein,...

Abstract

The embodiment of the invention discloses a testing method and device for eyeball tracking equipment, the equipment and a storage medium. The method comprises the following steps: acquiring a vertical distance between eyes of a user and a screen, and determining the vertical distance as a first distance; obtaining a plurality of calculation fixation points generated when the user watches the target fixation point; determining deviation angle information according to the plurality of calculation fixation points, the target fixation point and the first distance, wherein the deviation angle information comprises first deviation angle information and second target deviation angle information; and determining a test result according to the deviation angle information. According to the technical scheme of the embodiment of the invention, the accuracy and precision of the eyeball tracking equipment are represented through the deviation angle information, and the accuracy and reliability of eyeball tracking equipment testing can be improved.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of eye tracking, and in particular, to a testing method, device, device and storage medium of an eye tracking device. Background technique [0002] With the popularization and use of eye-tracking technology on VR / AR head-mounted devices and electronic devices, especially the realization and development of virtual reality technology, eye-tracking, as a must-integrate technology for VR devices, has gradually become more accurate and precise. It becomes a necessary basis for judging the performance of a VR device. Among them, accuracy refers to the difference between the calculated fixation point and the real fixation point when the user uses the eye tracking device, and accuracy refers to the degree of dispersion of the eye movement data when the user continues to fixate on the same target fixation point. [0003] Eye tracking, also known as gaze point tracking, is a technology that uses...
