Abstract:
Factories that mass-produce boiled eggs do not use eggs with minute surface irregularities as out-of-spec eggs in order to reduce the risk of damage during transportation. The inspection is performed visually by human workers to check for abnormalities, but this is a heavy burden on the workers because of the number of eggs they handle. In this study, a method to detect minute irregularities in eggshells using transmitted infrared light was attempted. By using an infrared camera to capture images of infrared light transmitted into the egg, we were able to detect areas where the shell was locally thicker. In the future, we plan to try deep learning to detect irregularities distributed on the sides near parallel to the optical axis of the camera by matching the three-dimensional shape of the shell measured by a 3D scanner with the transmitted infrared light image.
