Problems solved by technology

Most people do not have a general concept of the amount of dishes in their daily meals. They don't know how much they eat, so they can't control the amount of food well. At the same time, they can't know the energy corresponding to the dishes and the nutrients contained in them. , so that it is impossible to arrange meals reasonably

Embodiment 1

[0072] refer to figure 1 As shown, the present invention discloses a method for measuring and calculating dish quantity based on photographing, which specifically includes the following steps:

[0073] Step 1: collect the density information of all listed recipes;

[0074] Step 2: Collect the image of the recipe to be calculated and preprocess it;

[0075] Step 3: Perform image segmentation on the preprocessed image to obtain the dish area;

[0076] Step 4: Convert the actual area of ​​the dish according to different cameras;

[0077] Step 5: Model the volume of the dish according to the actual area of ​​the dish to obtain the volume of the dish;

[0078] Step 6: Calculate the amount of dishes based on the density of the dishes obtained in step 1 and the actual volume of the dishes obtained in step 5.

[0079] Step 1 includes: for each dish in the list recipe, use a measuring cup and a kitchen scale to measure the volume and mass of the dish respectively, and then calculat...

Abstract

The invention discloses a dish amount measuring method based on photographing. The method comprises the steps that 1 the density information of all listed recipes is collected; 2 a recipe image to bemeasured is collected and preprocessed; 3 the preprocessed image is segmented to acquire the area of a dish; 4 the actual area of the dish is converted according to different cameras; 5 the volume ofthe dish is modeled according to the actual area of the dish to acquire the volume of the dish; and 6 according to the dish density acquired in the step 1 and the actual dish volume acquired in the step 5, the amount of the dish is calculated.

Description

technical field [0001] The invention belongs to the technical field of visual measurement and calculation, and relates to a method for measuring and calculating vegetable quantities based on photographing. Background technique [0002] With the development of the digital health and medical information industry, people are paying more and more attention to their daily diet. At the same time, with the popularization of mobile devices, the acquisition of recipe images is becoming more and more convenient. Most people do not have a general concept of the amount of dishes in their daily meals. They don't know how much they eat, so they can't control the amount of food well. At the same time, they can't know the energy corresponding to the dishes and the nutrients contained in them. , so that it is impossible to arrange meals reasonably. This requires guidance on their diet to achieve a reasonable nutritional mix. Record the dishes you eat every day through the shooting functio...
