The invention provides a storage state detection method and a storage state detection system based on structure light. Storage state detection is carried out based on an infrared structure light source module, an image acquisition module and an image processing terminal; the infrared structure light source module and the image acquisition module are arranged on the opposite side of a storage cell; the image processing terminal is in communication connection with the image acquisition module; the infrared structure light source module is used for sending an infrared light band to the storage cell on the opposite side; the image acquisition module is used for acquiring an infrared image formed by irradiating an infrared light source on a storage cabinet, and transmitting the infrared image to the image processing terminal through an LIFI (Light Fidelity) light source; and the image processing terminal is used for comparing and matching the received image with a pre-extracted storage standard object under each state, and judging a storage state. According to the storage state detection method and the storage state detection system provided by the invention, the storage state is identified by adopting the structure light and the image processing difficulty is reduced; and meanwhile, the image is transmitted based on an LIFI technology, so that the communication reliability is improved, and the requirements that the storage state detection is carried out on warehousing sites with dense storage and irregular placement can be met.
Description
technical field [0001] The invention relates to the technical field of automatic detection, and relates to a storage state detection method and system based on structured light. Background technique [0002] In recent years, with the rapid development of my country's e-commerce industry, storage status detection has also begun to be widely used and developed. Storage status detection is an important part of modern large-scale logistics warehousing sites. Inventory information, including storage locations and storage status (including the number of storage items, whether the storage items are missing, and whether the storage items are stacked flat, etc.), is mastered at the auxiliary site. , It plays an important role in ensuring that the site realizes fast access to a large amount of materials. [0003] The traditional storage status detection method has been mainly based on manual inspection for a long time. At present, the automatic detection method of storage status app...
