Abstract:

Hot end inspection of glass bottles necessitates the localization of designed textures on that bottle. In this paper we proposed a method to localize designed textures on a test bottle by matching its image to a certain number of reference images and then mapping the texture to the test bottle. The intended purpose of this algorithm is to localize the designed texture on the bottle so that the designed texture areas and other areas on the image of the bottle can be distinguished. The localization is done by finding the amount of rotation caused due to the motion of the conveyor belt. The average orientation angle feature is used in the matching. Reference databases are created which contain necessary information regarding the different textured regions. A selected portion of the image is used to match the bottle at the hot end with the same area of the reference bottles. The design texture is marked, according to the appropriate match. All the methods involved experiments and results and conclusions based upon them are presented subsequently.
