[AI Image Inspection Case] Measurement of Nut Dimensions

We will measure the dimensions of the nuts using AI image inspection software and determine pass or fail!

We received an inquiry about nut measurement from a manufacturer of mission parts such as truck components. I believe that traditional methods of "image analysis" and "image processing" will not be completely replaced by AI (deep learning). Depending on the customer's wishes and operational conditions, we will consider more cost-effective proposals through free simple verification and report back. 【Inspection Settings and Results】 By using EasyInspector's "Dimension Angle Inspection" feature, we were able to measure one dimension in 0.52 seconds. In the left image, the good product was detected within the reference value and was deemed "pass." In the right image, when a different nut (with a different height) was attached, it exceeded the height reference value, resulting in a "fail" judgment.
