Document Type and Number:
WIPO Patent Application WO/2021/017396
Kind Code:
A1
Abstract:
Disclosed in the present invention are a test unit image extraction method and apparatus for a projector galvanometer, and an electronic device. Said method comprises: acquiring a projection image captured by an industrial camera; intercepting a region of interest (ROI) image from the projection image; on the basis of a brightness value of a preset monochrome channel of each pixel point in the ROI image and a preset brightness threshold, removing an incomplete test unit image from the ROI image, so as to obtain a processed ROI image; on the basis of the processed ROI image, obtaining the number of groups of test unit images having the same color as the preset monochrome channel; and using the number of groups to extract a group of test unit images from the processed ROI image.
