PROBLEM TO BE SOLVED: To provide a coil inspection method capable of calculating the linearity of a coil as an inspection object without giving any influence on cycle time while improving efficiency in coil inspection.SOLUTION: The coil inspection method includes: an image acquisition step S02 to acquire an image of a coil as an inspection object which is taken by using an imaging camera and an illumination; a binarizing processing step S03 to perform binarizing processing on the image; an edge extraction step S06 to extract edge of the coil as the inspection object; an integration graph creation step S08 to create an integration graph by integrating the extracted edge in a winding direction of the coil as the inspection object; and a linearity calculation step S09 to calculate the linearity of the coil as the inspection object based on the height of the integration graph. |
