Abstract

The invention provides a method, a system and equipment for acquiring an overall space contour of food. The method comprises the following steps of: amplifying a grid surface corresponding to a meal surface to an actual size; according to the boundary line of the meal and the container, obtaining the part, located at the lower part of the boundary line, of the grid surface of the inner surface of the container; and the grid surface of the meal surface with the actual size and the part, located at the lower part of the boundary line, of the grid surface of the inner surface of the container are combined into a closed space curved surface as the overall space outline of the food. The three-dimensional contour of the food in the three-dimensional space can be obtained, and accurate calculation of the volume of the food is facilitated. According to the invention, the boundary line between the food and the container can be accurately distinguished. The method can be widely applied to dietary nutrient identification and evaluation scenes.

Description

technical field [0001] The present invention relates to the field of food volume calculation, in particular, to a method, system and device for obtaining the overall spatial contour of food. Background technique [0002] Patent document CN105320955A discloses a food quality management detection module and a food quality management detection method using the same. The food quality management detection module includes a two-dimensional image capture device, a three-dimensional image capture device and an analysis unit. The two-dimensional image capturing device is used for acquiring a two-dimensional image of a lunch box filled with meal contents, and the two-dimensional image of the lunch box has a two-dimensional image of the meal contents of the meal contents. The three-dimensional image capture device is used to obtain the depth information of the style of the dishes in the catering content. The analysis unit is used to analyze the two-dimensional image of the lunch box ...
