Cable products have high requirements on thicknesses of insulation layer and shielding layer,and cable eccen-tricity,and there currently lacks portable equipment for measurement of high-voltage cable conductors.This paper reports a portable cable structure parameter tester designed based on the image multidivision method.Precision industrial camera and double telecentric lens are used as the camera unit,ring light source and LED backlight are used as the light field to obtain high-definition surface image of the object to be measured.By taking a number of cable photos in the way of transla-tion cable through the cable guide,the high-precision calibration field is established,the pixel space measurement is con-verted into actual physical spatial size,and the machine vision technology is used to measure large-diameter cable structure parameters automatically.The introduction of portable design and intelligent algorithm can effectively reduce the technical requirements of inspection personnel.Moreover,one-click operation and rapid measurement facilitate improvement in effi-ciency of cable inspection,which will greatly enhance the quality management of cable products.
