Dispersion measurement device and method for augmented reality equipment

Abstract

The embodiment of the invention relates to the technical field of the augmented reality, and discloses a dispersion measurement device and method for augmented reality equipment. In the embodiment ofthe invention, the dispersion measurement device for the augmented reality equipment comprises camera shooting equipment which is collinear with a main optical axis of the augmented reality equipmentand a processor, wherein the processor is in communication connected with the camera shooting equipment; and the processor is used for controlling the camera shooting equipment to capture a referenceimage and a test image which are displayed by the augmented reality equipment, and obtaining dispersion information of the augmented reality equipment according to the contour deviation between the captured test image and reference image. The embodiment of the invention further provides a dispersion measurement method for the augmented reality equipment. By adopting the embodiment of the invention, the dispersion of the AR (Augmented Reality) equipment can be objectively measured, the measurement is fast and efficient, and the accuracy is high.

Description

technical field [0001] The embodiments of the present invention relate to the field of augmented reality technology, and in particular to a dispersion measurement device and method for augmented reality equipment. Background technique [0002] Augmented Reality AR (Augmented Reality, referred to as "AR") is a technology that changes the direction of the light path through a prism, presents a virtual image that does not block the real world in front of people's eyes, and achieves a virtual-real fusion effect. When the light is refracted by the prism, the refractive index of the material will decrease with the decrease of the frequency of the incident light (or the increase of the wavelength), resulting in dispersion phenomenon, which will cause the focus of the image received by the AR device to be broadened, so that The reconstruction effect of the AR device image has declined. When the user uses the AR device to observe, the chromatic aberration and aberration will affect t...

Problems solved by technology

[0003] The inventors found that there are at least the following problems in the prior art: in the prior art, most of the dispersion tests for AR equipment adopt subjective testing methods, that is, observing some specific scenes with human eyes and making subjective judgments on them, which is costly. Less efficient and less accurate
