Abstract

The invention discloses a diopter testing device and method of a near-to-eye display system and a storage medium. The device comprises a testing lens group comprising a liquid lens, a sensor, a control system and a testing system, the to-be-tested near-to-eye display system is arranged at a preset position in front of the test lens group to display a test image; the sensor is arranged behind the test lens group for imaging; the control system is used for changing the focal power of the liquid lens; and the test system is connected with the sensor and is used for acquiring the imaging image corresponding to each focal power, determining the focal power corresponding to the imaging image with the highest definition according to the definitions of different imaging images, and determining the diopter of the near-to-eye display system to be tested according to the focal power corresponding to the imaging image with the highest definition. According to the near-to-eye display system, the display images of the near-to-eye display system to be tested under different diopters can be acquired through the sensor while the accuracy and stability of diopter adjustment are ensured, and finally the quality of the near-to-eye display system to be tested is evaluated from multiple aspects.

Description

technical field

[0001] The invention relates to the technical field of near-eye display equipment, in particular to a diopter testing device, method and storage medium for a near-eye display system. Background technique

[0002] In the fields of virtual reality (Virtual Reality, VR) and augmented reality (Augmented Reality, AR), a near-eye display system serves as a core display component to provide image display for users. For near-eye display devices with fixed diopters, there is a need to evaluate the applicable range of refractive error for the human eye; while for near-eye display devices with adjustable diopter, there is a need to test or calibrate the adjustable diopter of near-eye display devices .

[0003] The near-eye display system forms an image at a certain distance in front of the user through the principle of optics. Since the image formed by the near-eye display system is a virtual image, it cannot be measured by conventional means, and it needs to be measu...
