Abstract

The invention relates to a parameter detection method for an optical lens and a detecting instrument thereof. The detecting instrument provided by the invention comprises a reference image output displayer, a detected lens installation adjusting device, a camera, a lens parameter analysis measuring and controlling device and a detection conclusion output device, wherein a detected lens is arranged in the appropriate light source projection position between the reference image output displayer and the camera; reference images which are set by the output of the lens parameter analysis measuringand controlling device are used as the reference light source display of the reference image output displayer; video images which are projected on the camera through the detected lens are shot and transmitted to the lens parameter analysis measuring and controlling device; and the image parameters of the video images are compared with the image parameters of the reference images through the lens parameter analysis measuring and controlling device, thereby judging whether the detected lens is qualified or not through comparison and transmitting the detection conclusion of judgment to the detection conclusion output device to be output. The invention can automatically detect and judge the quality of the detected lens through the instrument and has the advantages of small errors and high detection efficiency.

Description

technical field [0001] The invention relates to an optical lens parameter detection method and a detection instrument thereof. Background technique [0002] The existing detection method of optical lens parameters is to place the measured lens between the light source and the projection wall, and manually judge the quality of the measured lens through the projected image, which is not only low in work efficiency, but also prone to errors. Contents of the invention [0003] In order to solve the above-mentioned problems existing in the prior art, the present invention provides a method for detecting optical lens parameters and its testing instrument, which can automatically detect and judge the quality of the tested lens through the automatic detection of the instrument, not only with small errors, but also with high detection efficiency . [0004] The technical solution of the present invention consists of the following two parts; [0005] Option 1: a method for detectin...
