Description
Technical Field

Background
Nowadays, with the continuous improvement of the technological level and the quality of life, the consumption market is rapidly increased, the superiority of the terminal market cannot be measured only by the sales volume, and people pay more and more attention to the terminal performance of products, including the aspects of the product stock laying rate, the popularization power, the price system, the terminal display and the like. Goods shelves, freezers and ground piles are common goods terminal display carriers, and the goods display not only needs novel themes and neat placement, but also needs clear price information and sales promotion information, so that the functional characteristics and the price information of the goods can be timely transmitted to customers, and further more consumers can be captured.
The reasonable and proper terminal display plays an important role in the sales volume of commodities, and the terminal retailer or enterprise manufacturer pays close attention to and pays close attention to the display condition of the terminal. And the display condition of the investigation terminal mainly depends on that a salesman visits a store, and manual inspection and statistics are completed. In order to improve the visit efficiency and the inspection quality of the salesmen and simultaneously feed back the real terminal display condition to the fast moving customer in time, the artificial intelligence technology is widely applied to the fast moving customer industry for commodity identification and business analysis. A salesman acquires terminal display pictures through a mobile phone end, identifies scene types (goods shelves, freezers, ground piles and the like), commodity types, the number of layers of the goods shelves, vacancy information, floor space and the like in the pictures based on a target detection algorithm, calculates and outputs corresponding business indexes such as the proportion of the product to competitive product commodities, whether the positions are golden and the like according to business requirements and the identification information, further can automatically judge whether the display conditions in the pictures meet business specifications or not, and feeds real and effective terminal information to enterprises in time, so that a data basis is provided for future sales decisions.
However, the pictures collected by the mobile phone only reflect image information of a two-dimensional space, and the amount of information that can be transmitted is limited, for example, in the case of oblique shooting, side shooting, dim light and the like, it is difficult for human eyes to capture information in a picture scene comprehensively and accurately. Particularly, because the field of vision of the mobile phone is limited, one picture hardly covers all display information of an overlong long shelf, and the display condition of the long shelf can be analyzed only by taking a plurality of pictures and splicing and restoring the pictures. And each time the image mosaic algorithm generates a mosaic result image, a lot of time and video memory computing resources are consumed, and the mosaic restored images are likely to have common visual effects.
