[AI Image Inspection Case] Dimension Inspection of Urethane

In the free evaluation service, we provide lighting, cameras, lenses, and other equipment to test whether the defects you want to see can be detected.

This is a request for a simple verification from a manufacturer of custom automatic machines that specializes in high precision and high-speed transport. By using the "Dimension Angle Inspection" feature of EasyInspector, it was possible to measure the dimensions of four sides using eight frames. In this setup, the dimensions are determined by the difference in values detected by the two frames. The left image shows the detection of the two frames. The right table indicates that Frame 004 is marked as "Fail" due to being outside the tolerance. Since we used a 5-megapixel camera this time, the width is 2592 pixels. With a field of view of approximately 700mm, the size of 1 pixel is calculated as "700mm ÷ 2592 pixels = 0.27". The sample product you sent was identifiable with the above precision, but ideally, we would like to conduct inspections with a tolerance of about 0.1 for 1 pixel. For example, with a 20-megapixel camera, the width would be 5400 pixels, making the size of 1 pixel 0.12, allowing for more accurate measurements. Therefore, verification with another sample is necessary. The current takt time was 0.44 seconds.
