The invention provides a system for checking the wrong selection of thin film filters based on machine vision. The system comprises a carrying box, a spectrum analyzer, a detecting device and an imagecomparison system; an arrangement area where the thin film filters can be distributed in an array is defined in the carrying box; the spectrum analyzer is used for performing spectrum analysis on thethin film filters arranged in the carrying box and transmitting a spectrum analysis result to the image comparison system; and the detecting device includes an illumination assembly which illuminatesthin film filters which are left after some thin film filters are selected from the carrying box and a camera for performing image acquisition on the thin film filters which are left after some thinfilm filters are selected, and transmitting image acquisition information to the image comparison system. Compared with the prior art, the system and the detection method perform spectrum test on thethin film filters to be detected, select qualified thin film filters, arrange the thin film filters into the detecting device for photo detection, and perform comparison detection in the image comparison analysis system so as to detect whether the thin film filters are wrongly selected or some qualified thin film filters are not selected.
Description
technical field [0001] The invention relates to the field of optics, in particular to a system and a detection method for checking whether a thin-film filter is picked wrong based on machine vision. Background technique [0002] After a batch of thin-film filters have undergone spectral detection and spectral judgment, some of them have poor or qualified spectral characteristics, and it is necessary to manually or machine remove the bad thin-film filters or pick out the qualified thin-film filters separately , In this process, there may be a problem of wrong picking, that is, the bad ones will be picked up as qualified ones, resulting in the failure of the optical device assembled with the thin film filter at the back end. The method of using artificial naked eyes to identify whether the thin-film filter is wrong is inefficient and error-prone. Contents of the invention [0003] In view of the above problems, the present invention provides a system for checking whether a ...
