[Abstract]:Automatic guided vehicle (AV) is widely used in many kinds of systems such as automatic warehouse flexible assembly system and logistics transmission system of commercial service industry due to its many advantages such as flexibility intelligence and so on. The wide application of automatic guidance vehicle not only reduces the labor cost, improves the production efficiency, but also effectively guarantees the reliability of material transportation. Automatic guidance vehicle (AV) integrates many core technologies such as information collection and processing technology, navigation technology, vehicle servo drive technology and so on. Navigation technology is one of the core technologies, and accurate positioning is the basis of navigation technology. At present, visual navigation technology has become a research hotspot with its best flexibility in theory, and the problem of visual positioning based on artificial road signs has been derived at the same time. In this paper, the problem of accurate positioning of automatic guidance vehicle by setting QR Code manual signpost is studied. The main contents of this paper are as follows: QR Code recognition. The principle of QR Code recognition is introduced in this paper. The binarization problem of QR Code image under the condition of uneven illumination is studied in detail, and the corresponding binary algorithm of QR Code image is proposed. This algorithm can be used to solve the binary problem of QR Code images with uneven illumination. The experimental results show that the proposed local binarization algorithm has good processing effect and low time cost. It can meet the requirements of embedded systems with high real-time performance. Automatic guidance vehicle position estimation section. This paper mainly introduces attitude representation, camera model, overall design and so on. This paper mainly introduces the location algorithm of automatic guided vehicle based on QR Code manual signpost and the algorithm of homing based on odometer, and combines the two algorithms to solve the problem of precise location of automatic guide vehicle in the indoor structured environment. The experimental results show that the proposed algorithm is robust and can meet the requirements of practical applications.
