Claim 0:
1. A method comprising:
capturing, by an image capturing device, a first image of a first item of goods at a first position on a shelf;
capturing, by the image capturing device, a second image of the first position on the shelf;
applying, by a processor, a difference method to the first image and the second image based on detecting differences between pixel values at corresponding pixel positions in adjacent images;
in response to applying the difference method, determining, by a processor, a category of a first item of goods and detecting that the first item of goods is removed from the first position on the shelf;
in response to determining the category of the first item of goods, sending, by the processor, to a manager terminal, a first prompt indicating the first item of goods has been removed from the shelf:
capturing, by the image capturing device, a third image at the first position on the shelf;
capturing, by the image capturing device, a fourth image of a second item of goods at the first position on the shelf;
applying, by the processor, a difference method to the third image and the fourth image based on detecting differences between pixel values at corresponding pixel positions in adjacent images;
in response to applying the difference method, determining, by the processor, a category of a second item of goods and detecting that the second item of goods is placed at the first position on the shelf;
in response to determining the category of the second item of goods, sending, by the processor, to the manager terminal, a second prompt indicating the second item of goods is different from a category of goods expected at the first position of the shelf;
recording, by the processor, a number of times of sending the second prompt and durations of the second item of goods whose category is different from the category of goods expected at the first position;
sending, by the processor, to a supplier computer, the number of times of sending the second prompt and an average of the durations of the second item of goods whose category is different from the category of goods expected at the first position to a supplier of the second item of goods.
