Image defect detection method and device, equipment and storage medium

Abstract

The invention discloses an image defect detection method, apparatus and device, and a storage medium. The method comprises the steps of obtaining a to-be-detected image; calculating a first edge curve slope and a second edge curve slope of the to-be-detected image according to the transverse direction parameter, the longitudinal direction parameter and the original coordinate information of the to-be-detected image; calculating a first included angle of the slope of the first edge curve and a second included angle of the slope of the second edge curve; and if the absolute value of the angle difference between the first included angle and the second included angle is greater than a preset angle threshold, determining that the to-be-detected image is defective. According to the method, the included angles corresponding to the two adjacent edges are calculated through the slopes of any two adjacent edges of the to-be-detected image, whether the to-be-detected image is defective or not is determined by comparing the absolute value of the angle difference between the included angles with the angle difference threshold value, intelligent image defect detection is achieved, manual detection is replaced, and the detection efficiency is improved.

Description

technical field [0001] The present invention relates to the technical field of image detection, in particular to an image defect detection method, device, equipment and storage medium. Background technique [0002] Before scanning a piece of media such as bills or banknotes, it is often necessary to manually detect whether each bill or banknote has a corner or defect, so as to ensure the image quality of the scanned bill or banknote. However, this method of manually checking whether bills or banknotes are bent or missing is time-consuming and inefficient. Therefore, an image defect detection method is urgently needed to replace manual detection and improve detection efficiency. Contents of the invention [0003] Based on this, it is necessary to address the above problems and propose an image defect detection method, device and computer equipment for solving the technical problem of low image defect detection efficiency in the prior art. [0004] In a first aspect, the pr...
