The invention discloses a method for recognizing the position of an object by a camera based on a self-service weighing and food taking system, which comprises the following steps: creating a template picture of a food clip, and setting a weight parameter of the food clip; installing a camera, so that the camera can normally communicate with a weighing system management background; using the weighing machine for feeding dishes, and according to dish types set in a dish warehouse of the management system, judging whether the dishes are taken by using a food clamp or not; for the dishes of which the types are 'weight', the camera realizing a camera shooting function on the dish areas before and after the user takes the dishes, and uploading pictures; the management background receiving a picture uploaded by the camera, the picture being preprocessed and then compared with an input food clip template picture, and recognizing a food clip; converting the recognized food clamp into actual coordinates according to coordinate calculation, and then judging the specific position area of the food clamp; and according to different position areas where the food clip is located before and after the user takes the food, completing weighing and billing of the weight of the food clip, and generating a corresponding settlement order.
Description
technical field [0001] The invention relates to the technical field of smart restaurants, in particular to a method for identifying the position of an object based on a camera of a self-service weighing and meal taking system. Background technique [0002] Self-service weighing and taking meals with smart electronic scales is a new smart restaurant construction mode that completes settlement for changes in the weight of dishes and accurately calculates to grams. Integrating cutting-edge technologies such as weighing and billing table, RFID binding, face recognition, and IoT billing display, ensures the diversity of users' diets. There are a variety of dishes, which can be taken on demand to avoid food waste, which will help promote the construction of CD-ROM demonstrations, save labor costs, and improve the dining experience. [0003] In actual dining, for the dishes that use the food clips, after the user finishes taking the dishes, he fails to put the food clips back to t...
