Non-contact tubing thread intelligent detection based on computer visualization technique

In consideration of the shortcomings of traditional contact type tubing thread parameter detection method, a non-contact intelligent detection system based on computer visualization technique is designed for tubing thread detection. After anintroduction of its principle and composition of the intelligent detection system, the method for tubing thread parameter detection with the intelligent system is introduced in detail, including image collection and preprocess, image sharpening, detection and extraction of the thread edge configuration, as well as the calculation and contrast of thread size detection.
