Inspection result presention apparatus, inspection result presention method and storage medium

Abstract

The present invention provides an inspection result presentation device capable of realizing an environment in which one or more thresholds for defect determination can be more easily determined. Theinspection result presentation device generates, on the basis of the inspection result information generated by the inspection result information generation process, a graph indicating the relationship between the first direction position of each defect and the feature amount and the one or more thresholds, and presents the graph to a user. In an inspection result information generation process, based on the image data of the surface to be inspected of the object to be inspected, a predetermined feature amount at each position of the surface to be inspected is solved; the obtained characteristic quantity at each position is compared with one or more threshold values, so as to determine a first direction position and the feature amount of each defect existing in the surface to be inspected,and generate the inspection result information including the identified first direction position and the feature amount of each defect and the one or more thresholds.

Description

technical field [0001] The present invention relates to an inspection result presentation device, an inspection result presentation method, an inspection result presentation program, and a storage medium for presenting the appearance inspection result of an inspected object to a user. Background technique [0002] In order to determine whether the product is manufactured normally, etc., a method is used to obtain the feature value (usually luminance value) of each part of the product surface based on the shooting results obtained by photographing the product surface with a camera, and the obtained feature value A device that detects defects by comparing with a certain threshold value (hereinafter, referred to as an appearance inspection device). [0003] According to the above detection process of defects, it can be seen that the existing visual inspection device will get wrong inspection results if the threshold is not an appropriate value, but the existing visual inspectio...

AI Technical Summary

Problems solved by technology

Therefore, when the threshold value is not an appropriate value, the conventional visual inspection apparatus needs to perform complex operations such as sequentially inspecting the feature value of each defect and determining an appropriate threshold value based on the inspection result.
