Hardware threads parameter automatic detection system based on PC architecture, mainly by the illumination system, a CCD camera and optical imaging systems, frame grabbers, image processing systems, mechanical detection system and electronic control system.
When measured after the lighting of the lighting system, by the CCD camera and optical imaging system threaded fasteners images and image acquisition card, digital images to a computer, the computer's digital image, calculated by the corresponding algorithm processing thread angle , the pitch circle diameter and other parameters of the collection section, and compares the calculated standard deviation.hydraulic hose assemblies
(2) software systems the thread parameters automatically detect software system include: system control module, an image processing module.
System control module: initialization; initial configuration of the complete system interface card image and standard parameters. The image processing; obtain and store an 8-bit grayscale image, the captured image into memory.
Image processing module of the image processing module, including noise reduction, the highlighted thread profile of the edge-information image preprocessing algorithms, detection and edge detection and contour extraction edge information extraction algorithm, measuring the actual size of the digital image system calibration algorithm , the parameters of the algorithm to calculate the thread.metric hydraulic hose fittings
