[AI Image Inspection Case] Detection of Wrinkles, Dents, and Impressions on Metal Balls

The AI image inspection software detects defects in metal products such as "ball wrinkles," "tapered area dents," and "tapered area impacts"!

We will verify whether we can detect "dents on the ball," "dents on the tapered section," and "indentations on the tapered section" based on a request from an industrial equipment manufacturer. By creating a striped pattern on the reflective part of the ball, it becomes easier to identify the dented areas due to the resulting step difference. 【Inspection Settings and Results】 We inspected 25 images, including 10 images of "dents on the ball," 5 images of "dents on the tapered section," 5 images of "indentations on the tapered section," and 5 images of "good products." Out of the 25 images, 22 were correctly identified as either good products or defective parts. The three images of "dents on the tapered section" could not be recognized as defective parts; however, considering that in actual operation, multiple shots (around 3 times) are expected to be taken during one full rotation, it does not necessarily mean that the defective parts that were not recognized in the verification will always go unrecognized.
