Inspection device, inspection method, and program

Abstract

To accurately detect presence or absence of a workpiece within a container.SOLUTION: An inspection device includes: an illumination device for illuminating the inside of a container; a polarizing camera having an imaging element in which polarizing filters having different transmission axis directions are disposed regularly; and a processing device. The processing device includes: an image acquisition section for acquiring an original image captured by the polarizing camera in a state in which the inside of the container is illuminated by the illumination device; an image generation section for generating an inspection image by removing a polarization component of a waterdrop from the original image; and a detection section for detecting the presence or absence of a workpiece within the container on the basis of an inspection image.SELECTED DRAWING: Figure 5
