Embodiment Construction

[0041] In order to enable those skilled in the art to better understand the solutions of the embodiments of the present invention, the embodiments of the present invention will be further described in detail below in conjunction with the drawings and implementations.

[0042] Aiming at the current problem that people need to manually calculate the calorie intake of food, there is a lack of automatic calorie calculation based on food. The present invention provides an estimation method and system for automatically identifying the calorie content of food. A three-dimensional model of the target food is established by acquiring the depth information of the target food, and the volume of the target food is calculated according to the three-dimensional model, and the target food is obtained by looking up a table. The density and unit calorie value of the target food are then calculated to obtain the mass and calorie of the target food. The present invention solves the problem that ...

Abstract

The invention provides an estimation method for automatically identifying food calories, which comprises the following steps: obtaining depth information of a target food, and establishing a three-dimensional model of the target food according to the depth information; wherein, the depth information comprises size information, shape information, distance information and point cloud data information; The three-dimensional model is voxelized to generate a voxelized model with set specifications, and the volume of the target food is calculated according to the voxelized model; Obtaining the foodname of the target food, and obtaining the density of the target food according to the preset food name and density correspondence table; According to the volume and the density, the mass of the target food is calculated, and the calorific value of the target food is obtained by querying a preset calorific meter. The present invention can solve the problem that people need to manually calculate calories for intake of food and lack automatic identification of food calories, and can improve the accuracy and convenience of calculation of food calories.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to an estimation method and system for automatically identifying food calories. Background technique [0002] With the development of society, people's diet is becoming more and more abundant, and the intake of food calories is also increasing. Excessive intake of calories will be stored as fat in the body. Abnormal accumulation of fat in the body will lead to obesity and Unnecessary burden, and can become a risk factor for cardiovascular diseases, certain cancers, diabetes and other epidemic diseases. Coupled with the development of science and technology, people's outdoor work has been reduced. This lifestyle of eating more and moving less has made many people more and more obese. [0003] Although some applications now provide calculation methods such as daily calorie intake, so that users can understand their daily food intake. However, because the operation is usually more ...
