Label position deviation detection method and device and detection equipment

The invention provides a label position deviation detection method, a label position deviation detection device and detection equipment. The method comprises the following steps: acquiring a to-be-detected image containing a label of a to-be-detected workpiece; segmenting the to-be-detected image based on a pre-stored segmentation template, selecting an identification region containing the label from the to-be-detected image, and obtaining region pairs by dividing adjacent regions on the periphery of the identification region; for each region pair, calculating an area difference value of two sub-regions in the region pair, and comparing the area difference value with a corresponding error threshold value; and judging the position deviation condition of the label according to the comparison result. According to the method, low-cost, accurate and efficient label position offset detection can be realized by comparing the size of the offset area, and the detection and flow line production efficiency is improved;
