To provide an apparatus capable of surely making workmen visually recognize the groups of very small flaws which are produced, when coatings are repaired and of objectively determining the quality of coatings, without having to depend on sensory properties of workmen.
The coating inspection apparatus 8 is provided with an illumination means 11 for irradiating light to a section Fa to be inspected of a coated surface F; an imaging means 12 for imaging a light reflected at the surface of the section Fa to be inspected; an image processing means 21 for processing images at reception of signals from the imaging means 12; a displacement detection means 13A for detecting the distance between the surface of the section Fa to be inspected and the imaging means 12; a perpendicularity determination means 13B for detecting the perpendicularity between the surface of the section Fa to be inspected and the optical axis of the imaging means 12; and a determination means 13 for determining whether the distance and the angle between the imaging means 12 and the surface of the section Fa to be inspected are in an inspectable state at reception of signals from the displacement detection means 13A and the perpendicularity determination means 13B. Ultrasonic displacement sensors are adopted as the displacement detection means 13A and the perpendicularity determination means 13B, and enable simultaneous detection of the distance and the perpendicularity.
