A Cable Sheath Material Thickness Measurement Method Based on Image Measurement Technology

Abstract:

Sub-pixel positioning is a key technology in geometry measurement field. Reckoning on the low accuracy of ordinary polynomial interpolation for sub-pixel positioning method because of losing the position of edge points, an improved Sobel edge detection method is first proposed, and then is applied to the thickness measurement system of cable sheath material. The experiment shoes that the edge coordinateonthe detected by our proposed interpolation method is more colse to the real edge than the original method.
