The whole system is implemented under VC++ platform. Firstly,the amplifi- cation coefficient of microscope is calibrated and image is captured. Secondly, binary processing of image is carried on through soft programming in this measuring system,and then edge outline of image is identified by edge detection based on Roberts operator. Finally,the cable insulation layer parameters are measured by using the amplification coefficient of microscope. On the basis of this measuring system, a lot of cable insulation layers were tested, and experimental results show that this system is reliable, highly accurate and easy to give solutions for measuring cable insulation layer parameters.
