Method and system for identifying salient-point mould number of revolution-solid glass bottle based on images

The invention relates to a method and system for identifying a salient-point mould number of a revolution-solid glass bottle based on images. The method comprises the following steps of: 1) rotating the to-be-identified glass bottle on a turn table, and triggering a camera to collect a panoramic image containing a pitting mould number area by virtue of a photoelectric sensor and a rotary encoder;2) preprocessing the collected image to improve the quality of the image; 3) on the basis of smoothening the image rapidly by virtue of an integral image, segmenting the image by virtue of a dynamic threshold, and carrying out morphologic processing on the image to improve the segmentation effect, screening salient points of a mould according to the features (such as shapes, area and coordinates and the like) of the salient points of the mould, and extracting the coordinates of each salient point; 4) according to the distance relationships among the salient points, calculating corresponding symbolic expressions; and 5) inquiring a glass bottle mould code table, and determining the mould number according to the symbolic expressions obtained in the step 4). According to the invention, lightpaths are transformed by a mirror, thereby satisfying the needs on the space layout and adjustment of equipment; the collection of the high-definition salient-point images of the mould is ensured; and the identification system is simple in structure, low in cost, high in precision, high in speed, and easy to popularize and use.
