Title: IMAGE INSPECTION DEVICE, PRODUCTION SYSTEM, IMAGE INSPECTION METHOD, PROGRAM, AND STORAGE MEDIUM
Abstract:
Provided is an image inspection device having high detection precision with respect to a color image as well as high orthogonality, and in which the computation time for determination processing is short, initial setting is easy, and the cost thereof is low. This image inspection device 1 is characterized by being provided with: an imaging means 18 for capturing an image of an inspection object as a color image 40; a meshing means 31 for dividing the color image 40 into a mesh shape; a pre-processing means 32 for converting the color image 40 into a predetermined grayscale; a reference image storage means; a determination means 34 including template matching for determining a degree of similarity on the basis of a predetermined parameter for each of a plurality of divisions of the mesh shape for a reference image 40R and an inspection image 40T captured by the imaging means 18, the inspection image 40T being divided into a plurality of divisions in a mesh shape by the meshing means 31 and the pre-processing means 32 and converted to the predetermined grayscale; and an interface means 30.
