AI Technical Summary
Existing detection methods are insufficient to achieve accurate quantitative measurements on the inner surface of catheters, especially in confined spaces. Optical 3D scanners cannot enter and are complex to operate, while endoscopes rely on human visual observation and cannot provide precise values.
A laser ranging-based device for measuring defects on the inner surface of a conduit is used. It includes a hollow shaft, a support and positioning mechanism, a measuring head, and a rotation drive mechanism. The device uses a laser displacement sensor in conjunction with an optical camera to obtain the depth or height of defects through rotation and axial movement.
It enables precise quantitative measurement of defects on the inner surface of catheters. The device is compact, low-cost, easy to operate, avoids secondary scratches, adapts to different inner diameter specifications, and provides intuitive and accurate measurement results.
