AI Technical Summary

Problems solved by technology

It may be that using AI to learn and render scenes cannot be fully realized in real time, and further optimization of the algorithm running speed is required
Generally speaking, the shortcomings of the current existing technology are that it is expensive, not close to the people, not real-time, and many related tasks require wearing glasses, which cannot be done with naked eyes.

Embodiment 1

[0046] A method for realizing a penetrating screen system based on camera eye tracking, comprising the following steps:

[0047] 1). First of all, it is necessary to solve the problem of detecting the eyeball and measuring the distance of the monocular camera. In order to solve this solution, it is first necessary to perform a calibration experiment on the camera to obtain the required data;

[0048] According to the camera pinhole model, there are the following formulas: Among them, f is the known focal length of the camera, which is 35mm, d is the distance from the object to the camera, x is the distance between the pupils after imaging, and w is the actual distance between the pupils of the user's eyes. The interpupillary distance of the tested user is 62mm . First fix d to find x, and at the same time obtain the pixel spacing p of the binocular pupils after imaging, then a represents the length distance of the unit pixel, unit: mm / pixel;

[0049] After that, the eyeb...

Abstract

The invention relates to a method for realizing a penetrating screen system based on camera eye tracking, which belongs to the field of augmented reality technology, and includes the following steps: firstly, determine the eye position in the camera coordinate system, then establish a standard coordinate system, and set the camera coordinate system Convert to the standard coordinate system and then convert to the Unity coordinate system, map the real screen and eyes to the unity coordinate system, and align with the camera in the virtual scene after a series of transformations and calibrations, so that users can use only their eyes to interact with the system achieve interactive effects.

Description

technical field [0001] The invention relates to a method for realizing a penetrating screen system based on camera eye tracking, and belongs to the technical field of augmented reality. Background technique [0002] At present, eye tracking technology has been applied in various fields. In terms of human-computer interaction, controlling computers through eyes has become a feasible interaction method. Eye tracking can also be used to analyze user psychology, so that programmers can carry out web page layout planning, personalized advertisement recommendation and other work, making the most important information easier to be captured by users. In the medical field, eye tracking can also help to check the condition of patients' eyes more conveniently. Some people with disabilities or people with very limited mobility can use eye trackers to achieve more convenient interactions. In the field of security, eye tracking helps machines better identify human eye features and achie...
