摘要： An inspection apparatus includes: a camera for acquiring an image of the whole area of an end face of the tubular product; a first light source for illuminating an outer peripheral edge of the end face side of the tubular product over the entire circumference thereof, a second light source for illuminating an inner peripheral edge of the end face side of the tubular product over the entire circumference thereof; and a third light source for illuminating an inner peripheral surface of the end face side of the tubular product over the entire circumference thereof. The apparatus uses the image of the tubular product using the first and second light sources to calculate an outer diameter and a wall thickness of the tubular product and illumination from the third light source for detecting a surface defect on the inner peripheral surface of the tubular product.
