The invention discloses a pistachio nut head and tail recognition device and method based on optical coding and deep learning. The device comprises a supporting platform, a conveying mechanism and a supporting frame are arranged on the supporting platform, pistachio nuts are placed on the conveying mechanism, an industrial camera is connected to the supporting frame and right faces the conveying mechanism, an RGB structured light source is further connected to the supporting frame, and a coaxial light source is further clamped between the RGB structured light source and the industrial camera.According to the detection device, three-color RGB light and coaxial light are adopted, and multi-angle imaging is carried out on an object. According to the method, the head-tail transition curved surface of the pistachio nut has obvious difference from the change angle of the outline skeleton, based on four light sources in different colors of a coaxial white light source and the RGB three-colorstructure light sources, the ends of the pistachio nuts are imaged from different angles, different contour transition curved surfaces of the pistachio nuts show different colors and become two-dimensional color codes after camera imaging, the distinguishing degree of the heads and the tails of the pistachio nuts is enhanced, and the recognition rate of a network is increased.
Description
technical field [0001] The invention relates to the technical field of automatic optical detection, in particular to a pistachio head and tail recognition device and method based on optical coding and deep learning. Background technique [0002] In the market, the quality and price of pistachios that are naturally opened and machine-opened are different. In order to maximize the interests of the enterprise, it is necessary to distinguish the natural open pistachios from the machine open pistachios at the beginning of processing in the factory. The annual output of pistachios is huge. If you rely on artificial eyes to detect, it is not only inefficient but also expensive. Can not meet the needs of enterprises. Therefore, there is an urgent need for automatic and efficient intelligent products to replace manual opening recognition of pistachios. To identify the opening, it is first necessary to identify the head and tail of the pistachio. Contents of the invention [000...
