More Information
Summary:The invention discloses a frame image size measuring method and device based on CAD and a medium. The method comprises the steps of obtaining a to-be-detected frame image; inputting the frame image to be measured into a pre-constructed CAD measurement model, and determining an alignment region of interest corresponding to the frame image; obtaining an alignment region-of-interest template corresponding to the alignment region-of-interest, and generating an affine transformation matrix; and performing size measurement on the to-be-measured frame image according to the alignment region-of-interest template and the affine transformation matrix to obtain an actual measurement result of the frame image. The problem that size measurement cannot be automatically completed for the frame image is solved, it is guaranteed that size measurement can be accurately and timely conducted on the frame image, the phenomenon of measurement errors caused by inaccuracy of the standard frame image is reduced, and labor cost and ti
