Method and device for identifying nutrition information contained in food

Abstract

The invention discloses a method and a device for identifying nutrition information contained in food. The method comprises the steps of firstly, collecting images of food from at least two differentangles to obtain multi-angle images of food; then, performing three-dimensional model reconstruction on the food according to the multi-angle image to obtain a three-dimensional model in a proportionof 1: 1 to the actual size of the food; then, carrying out three-dimensional model deconstruction on the three-dimensional model to obtain information such as food names, food volumes and food types;carrying out association matching on the information and data in a pre-established food nutrition information database to obtain nutrition information contained in the food; and then, displaying the nutrition information contained in the food. Therefore, more accurate nutrition information or calorie information can be obtained. Moreover, compared with a mode of obtaining the nutrition informationcontained in the food through manual search and calculation, the mode is more convenient.

Description

technical field [0001] The present invention relates to the field of Augmented Reality (AR for short), in particular to a method and device for reconstructing a three-dimensional model and identifying nutritional information contained in food using AR technology. Background technique [0002] Modern people pay more and more attention to the quality of life, especially in terms of diet, they are increasingly pursuing a reasonable nutritional formula. To do this, people need to know the nutritional content and calorie count of various foods. [0003] The traditional method is to search for food nutritional information or calorie information through terminal input, and further calculations are required based on the weight or volume of the food to obtain more accurate nutritional information or calorie information. But this process is very cumbersome and practical. [0004] In recent years, with the rise of AR technology, AR technology has also been applied to the scene of ide...

But this process is very cumbersome and practical

[0004] In recent years, with the rise of AR technology, AR technology has also been applied to the scene of identifying the nutritional information contained in food, but this type of solution still has the following problems: 1) The identification calculation is mainly performed from a single perspective, and the single perspective It is inevitable that there will be blind areas that cannot be covered, which will easily cause inaccurate nutritional information and calorie information.

2) It is impossible to identify multiple foods across scenarios, and it is also impossible to compare the nutritional information or calorie information of multiple foods on the same interface
