Picture-based food nutrition analysis method and device and calculation equipment

Abstract

The invention discloses a picture-based food nutrition analysis method and device and calculation equipment. The method includes: acquiring at least one food picture; inputting the at least one food picture into a semantic segmentation module, which is obtained through training, to obtain a semantic segmentation result of each food picture, wherein the semantic segmentation result contains a segmentation result of each food material in the food picture; carrying out three-dimensional modeling according to the semantic segmentation result of the at least one food picture, and estimating and obtaining volume information of each food material; analyzing nutrient composition and / or calorie information of each food material according to the segmentation result and the volume information of eachfood material; and calculating and obtaining nutrient composition and / or calorie information of a food in the food picture according to the nutrient composition and / or the calorie information of eachfood material. Therefore, by utilizing the solution of the invention, the nutrient composition and / or the calorie information of the food in the food picture can be quickly obtained, and then a reference suggestion can be provided for diet of a user.

Description

technical field

[0001] The invention relates to the field of computer technology, in particular to a method, device and computing equipment for food nutrition analysis based on pictures. Background technique

[0002] At present, with the improvement of living standards, people are more and more concerned about their own health. From the perspective of diet, people have gradually changed from caring about eating well to whether they are healthy or not, that is, paying attention to the nutrients in food and The content of indicators such as calories. For example, for a young woman who wants to maintain a shapely body, the calorie content of the food is desired; for a cardiovascular patient, the fat content of the food is urgently needed; and / or for the diabetic, the carbohydrate content of the food is needed Compound content. It can be seen that a technology that can quickly estimate the nutritional content and calorie content of food on the plate is in urgent need. [0003...

Examples

Embodiment Construction

[0058] Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited by the embodiments set forth herein. Rather, these embodiments are provided for more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

[0059] The present invention takes into account that a considerable number of groups are extremely concerned about the nutritional content and calories of food. At the same time, it is noted that camera applications have gradually become an indispensable part of people's daily life, such as Faceu, beauty cameras, and pepper cameras. And so on, and the users who use these camera apps are usually mostly women. These users also have a co...
