Embodiment Construction

[0043] next to figure 2 As an example to describe the implementation mode:

[0044] 1. Put the glasses on figure 2 on the glasses support platform;

[0045] 2. The display screen 1 displays a standard image. Taking phase shift fringes as an example, the display image sequentially displays fringe images of different horizontal and vertical phases. Corresponding image acquisition is performed by the image collector A4 and image collector B5 controlled by the industrial computer, which can be collected Figure 4 image shown.

[0046] 3. Through the analysis of the phase shift fringes, the screen surface position coordinates corresponding to the pixels inside and outside the lens on the image can be obtained;

[0047] 4. According to the method in the patent "a new type of lens focal length detection method and device" application number or patent number: 201710578993.4, the internal points of the lens are calculated, and the surface distribution of the lens focal length and ...

Abstract

The invention discloses a novel glasses optical parameter global detecting method and device. According to the method and device, a display screen (1) is placed in front of lenses, glasses to be tested (2) are placed between the display screen (1) and an image collector through a glasses support table (3), the image collector is located behind the lenses, and a controller (6) is connected to the display screen (1) and the image collector through a cable. By means of the method and device, fast accurate measurement of glasses parameters can be achieved. Meanwhile, the method can be popularizedto multi-lens parameter detection, and is suitable for various VR glasses, 3D glasses, telescopes and other complex optical lens systems.

Description

technical field [0001] The invention relates to the field of glasses, in particular to a novel global detection method and device for optical parameters of glasses. Background technique [0002] In addition to the degree of glasses, the optical parameters of glasses also include the center position and center distance of the lenses on both sides (corresponding to the position and interpupillary distance of the human eyes). Astigmatism glasses also include the axial position of the lens installation and the astigmatism degree. Even if the prescription of the glasses is appropriate, the deviation of the center position will still affect the comfort of the glasses. [0003] At present, the testing of spectacle lens parameters mainly uses a measuring instrument called a focal meter. The inspector needs to measure the power of the two lenses of the glasses on the focal meter one by one. However, there is no suitable equipment for spectacle overall parameter testing. The global p...
