Method for automatically adjusting AR virtual image brightness based on pupil size

Abstract

The invention discloses a method for automatically adjusting AR virtual image brightness based on pupil size. The method comprises the following steps: step 1, a user customizes the virtual image brightness in different environment modes; 2, under the virtual image brightness customized in the step 1, the pupil diameter of the user is acquired; 3, the pupil diameter of the user in the process of using the AR display equipment is acquired, the pupil diameter at the current collection moment is compared with the pupil diameter data of the user obtained in the step 2, and the virtual image brightness in the current use environment is adjusted according to the comparison result; according to the invention, the brightness of the virtual image presented by the AR device in the visual field of the human eyes can be automatically adjusted, the brightness difference between the virtual image presented by the display device and the external environment can be adjusted, and the situation that thevirtual image cannot be seen clearly when the external light is too strong or the virtual image is too dazzling when the environment is too dark is avoided.

Description

technical field [0001] The invention belongs to the technical field of adjusting the brightness of an AR virtual image, and in particular relates to a method for automatically adjusting the brightness of an AR virtual image based on pupil size. Background technique [0002] With the increasing development of information technology and high-tech industries, many devices based on augmented reality technology (Augment Reality, AR) are gradually entering people's lives. Augmented reality technology can present virtual information in the real world, and the real environment and virtual objects exist in the space at the same time. When using the AR head-mounted display device, the user can not only see the real scene outside, but also see the virtual scene presented by the AR display device at the same time. Therefore, the light entering the user's eyes is composed of the external real scene and the virtual scene generated by the device. [0003] The display effect presented to ...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to solve the problem that the brightness difference between the virtual image presented by the display device and the external environment is too large, which leads to the poor display effect of the virtual image presented by the device in the field of view, and provides an automatic adjustment AR based on pupil size. The method of virtual image brightness, which can automatically adjust the brightness of the virtual image presented by the AR device in the field of view of the human eye, without using additional photosensitive devices to detect the light intensity of the environment
