Abstract | The invention discloses a commodity displacement identification method based on gravity sensor data, thereby solving a problem that the existing unmanned vending cabinet is easy to judge mistakenly. The core principle of the method is to judge that the gravity value of one gravity sensor is decreased and the gravity value of the other gravity sensor is increased within short time, and the change amplitudes of the two gravity sensors are the same. According to the invention, a commodity dynamic list is constructed as a cache table based on the value changes of the gravity sensors; the identification speed is high; and the process that a user picks up a commodity and puts back the commodity can be accurately identified. According to the invention, a user can place commodities on any commodity shelf; the vending cabinet can accurately judge whether the commodities in the vending cabinet are reduced or not, can judge that a user does not take away the commodities, so that users can take and place the commodities |
