Abstract
A method for inspecting the stripped condition of an electric wire permits inspection of electric wires having a tip portion of various configuration with high accuracy and reliability. In this method, stripped condition is judged to be good or not good by: illuminating a core 6 at a tip portion of the electric wire 4 and its vicinity by means of illumination means 11; imaging the core and its vicinity by means of imaging means 12, the imaging means disposed in opposite relation to the illumination means 11 with the electric wire 4 therebetween; determining coordinate position of stripped end of the sheath in an imaging plane using illumination data of a picture obtained by the imaging means; determining coordinate position of the tip end of the core 6 in the imaging plane, as well as shape of the core 6, such as inclination of the core 6; determining as to whether the coordinate position of the stripped end is within a standard range, whether length and thickness of the core are within a standard range, or whether strands come out of the core.
