AI Technical Summary
Technical Problem
Existing technologies have a high false positive rate in detecting debris on target objects, making it difficult to accurately identify whether debris exists on the surface of the workpiece.
Method used
By acquiring images of the target object, obtaining its center position, dividing the detection area, obtaining the image histogram of each area, and analyzing the histogram to determine whether there is debris at the edge.
Benefits of technology
It improves the accuracy of debris identification, reduces false alarm and false negative rates, and is suitable for defect detection in complex backgrounds.

Abstract
Some of embodiments of the present application provide an image histogram-based target object edge chipping detection method, a device, a medium, and a product. In the embodiments of the present application, an image of a target object is collected, and a central position of the target object in the image is acquired; at least two detection regions of the target object are determined on the basis of the central position; image histograms of the detection regions are acquired; and the image histograms of the detection regions are analyzed, and whether there are clippings at the edge of the target object is determined on the basis of the analysis result.
