| Abstract: | A non-contact automatic measuring systemof thread parameters based on an array CCDvision measurement technique has been designed and achieved. Thread parameters ,such as thread angle,screwpitch,lead,helixangle,thread height ,major diameter ,pitch diameter ,minor diameter etc ,can be real-timely and accurately tested.In order toimprove their measurement precision,some keytechniques , for examplei mage preprocessing,edge detection and sub-pixel location,have been emphatically investigated. The experimental re... |
