APPEARANCE INSPECTION APPARATUS AND APPEARANCE INSPECTION METHOD

摘要

Visibility of defects is improved for inspection of structures and the like, by generating an image having higher resolution than pixel resolution of a TV camera itself. An appearance inspection apparatus is provided with a TV camera (101); a camera driving device (102) for making the TV camera scan an inspection object; an image fetching device (105) for fetching the image in the TV camera as a digital image; a camera motion measuring device (104) for measuring scanning motion of the TV camera; a highly fine image generating device (106), which generates a highly fine image having a higher pixel resolution than that of the TV camera, based on the digital images fetched by the image fetching device and the TV camera scanning motion data measured by the camera motion measuring device; and a recording device (108) which records and stores positional information of the inspection object.
