Description
Technical Field
The invention relates to the technical field of shelf detection, in particular to a single-chip multi-lens-based shelf detection method.
Background
With the continuous and steady development of the economy of retail industry in China, the scale of a large supermarket is continuously enlarged, and the problem of shelf commodity management is also generated. The unmanned supermarket further improves the demand of intelligent commodity management of the goods shelf. Traditional supermarket management mainly depends on manpower, and shelf commodity management requires a large amount of labor force; the 'unmanned supermarket' is mainly based on a radio frequency identification (FRID) scheme, can complete basic intelligent management, such as intelligent cash collection, but the goods on shelves are not detected to be out of stock and have no corresponding intelligent processing scheme. Most of the existing patents are based on scanning the bar code containing the cargo information for identification, and the method is an indirect identification method and is complex to operate in practical application.
The invention discloses an intelligent detection device and method for goods shortage of a goods shelf, aiming at enabling a camera to be driven by a steering engine to turn over, enabling goods information of the goods shelf to be obtained quickly through a single camera without a large amount of labor force and enabling the goods information to be updated timely. The disadvantage of this method is that the camera lens is movable, the driving cost of the movable structure is very high, and the shelf detection can be realized only when the camera lens is rotated and turned over to a certain shelf, so that the transmission detection efficiency is still to be improved.
