WIPO Patent Application WO/2020/152866
Kind Code:
A1
Abstract:
In the present invention, an illumination camera unit having first to third lamps and a line sensor camera is moved by an articulated robot. An image inspection unit, for example, combines captured images of wavelength ranges A and B, combines captured images of wavelength ranges A to C, and combines captured images of wavelength ranges C to F. Thereafter, the image inspection unit performs image inspections of a plurality of captured images having been generated as described above. On the basis of the captured images of different wavelength ranges, the image inspection unit individually performs image inspections of the respective captured images. When it is determined that there is a defect in one of the captured images, the image inspection unit determines that there is a defect in the inspection target and causes a display unit, for example, to perform display accordingly.
