Fusebox Inspection

Machine Vision Tool(s) | Color Matching |
The fusebox inspection determines if all the color-coded fuses are present and in the correct locations in the fuse box. The application uses color matching to compare the color information at each fuse socket in the image with the expected color for the fuse.
Color Matching—Compares the color information contained in the fuse labeled 20 with the color information in two predefined regions where you expect to find the fuse. In this application, it is assumed that the fuse boxes you are inspecting are always located at the same position in the image. The Color Matching function calls on the color information of the fuse, which has been learned and stored in the script. That color information is compared with the color information in the search regions. If the correct fuse is identified, the Color Matching function returns a match score greater than 750. If the correct fuse is not present in either of the search regions, the Color Matching function returns a lower score and the fuse box fails the inspection process.
Color Matching—Compares the color information contained in the fuse labeled 25 with the color information from two predefined regions in the image where you expect to find the fuse.

Note There are two types of colors associated with the fuse labeled 3, so color matching is performed twice (steps 3 and 4). |
Color Matching—Compares the color information contained in the first type of fuse labeled 3 with the color information from two predefined regions in the image where you expect to find the fuse.
Color Matching—Compares the color information contained in the second type of fuse labeled 3 to same regions used in Step 3.
The fusebox passes inspection for the fuse labeled 3 if each of the two search regions passes at least one of the color matching tasks defined in Steps 3 and 4.
Color Matching—Compares the color information contained in the fuse labeled 10 to a predefined region in the image of the fusebox where you expect to locate the fuse.
