| Abstract: | In order to improve the testing efficiency of thread and realize multi-parameter test at a low cost,a thread picture-capturing system was established through designing calibrating method and choosing right camera and lamp-house.A program was written by designing and optimizing arithmetic.With this system,the application of image analysis technology was researched for thread test,and the uncertainty of the measurement system was evaluated.The experimental results demonstrate that it can be realize to measure thread automatically based on image analysis technology. |
