Abstract

The invention provides an AR imaging system virtual image distance testing method and device. The method comprises the following steps: calibrating a camera to acquire a corresponding relation betweena Focus value at each location and the virtual image distance; adjusting an adjustable lens by using the Focus value of the first preset stepping, enabling the camera to perform the first shooting onthe virtual image formed by the to-be-tested AR product, thereby acquiring the Focus value of the picture with the highest definition in the first shot picture; taking the acquired Focus value as thecenter, and adjusting the adjustable lens of the camera by using the second preset stepping, enabling the camera to perform the second shooting on the virtual image formed by the to-be-tested AR product, and acquiring the virtual image distance of the to-be-tested AR product according to the Focus value of the picture with the highest definition in the second shot picture, and the corresponding relation between the Focus value of each location and the virtual image distance. Through the method provided by the invention, the virtual image distance of the AR product can be tested, and the testing precision is high, the cost is low, the high virtual image distance testing efficiency is realized, and the method is suitable for testing the virtual image distance of the large-batch AR products.

Description

technical field

[0001] The present invention relates to the technical field of optical testing, and more specifically, to a virtual image distance testing method and device for an AR imaging system. Background technique

[0002] AR (Augmented Reality, Augmented Reality) technology is to simulate physical information (such as visual information, sound, etc.) Virtual information is applied to the real world and perceived by human senses, so as to achieve a sensory experience beyond reality. Augmented reality technology not only shows real world information, but also displays virtual information at the same time, and the two kinds of information complement and superimpose each other. Glasses made using AR technology can overlap the real world with computer graphics, and you can see the real world surrounding it.

[0003] AR products are currently widely used in military industry, engineering design, consumer electronics, and medical treatment. At present, the mainstream AR pr...
