Measurement Method of Yarn Tension Based on CCD Technology
As to the disadvantages of traditional contact measurement methods, a non-contact measurement system of yarn tension based on CCD technology is developed, which includes the system working principal and the structure ,the design of area matrix CCD driving circuit, the binary process of video signal boundary features by comparison method. Experimental data from contact measurement and non-contact measurement is contrasted, and the measurement error is analyzed. Experimental results show it is achieved with high accuracy and reliability.
