One or more embodiments of this specification also relate to a position identification system, a computing device, and a computer-readable storage medium. BACKGROUND An electronic shelf label (ESL) is an electronic display apparatus placed on a shelf to replace a paper shelf label and used to display commodity information such as the price, name and origin of a product. The electronic shelf label may receive shelf label information issued by a server and display, on its display screen, commodity information in the shelf label information, reducing the cost of changing commodity information for the paper shelf label and improving the update efficiency. Commodity display inspection is a high-frequency rigid demand in the retail industry. At present, commodity display inspection needs an inspector to determine placement positions of each electronic shelf label and a corresponding commodity, and compare placement positions of all electronic shelf labels with a display effect diagram, thereby finding out an incorrectly placed commodity object. This way of inspection may consume a lot of labor costs and time costs. There is another way of inspection where an inspector confirms display information of an electronic shelf label through image identification, and then determines whether a position of the electronic shelf label and its corresponding commodity are placed correctly. This way of inspection raises high requirements on an image identification system, resulting in too high implementation costs. Therefore, how to implement automatic determination of a placement position of an electronic shelf label in a low-cost manner is an urgent problem to be solved at present.
