System and method for providing nutrition information using artificial intelligence

A system for providing nutritional information based on image analysis using artificial intelligence, the system comprising:

• at least one imaging device acquiring at least one image including at least one dish or at least one food contained in each dish;
• a service providing apparatus for detecting at least one food included in the at least one image when the at least one image is received, confirming a name of each detected food on the basis of a learning model, mapping food information included in pre-stored food information on the basis of the confirmed name, and generating nutritional information using the mapped food information;
• and
• a user terminal for visualizing and displaying the nutritional information when the nutritional information is received,
• wherein the pre-stored food information includes at least one among name information, recipe information, nutrient information, and basic weight information of the at least one food,
• wherein the recipe information includes basic ingredient information including at least one ingredient necessary for cooking relevant food and weight information of each of the at least one ingredient, and
• wherein the service providing apparatus generates recognized ingredient information by recognizing ingredients of the at least one food included in the at least one image, and generates final ingredient information by collecting ingredients included in the recognized ingredient information and the basic ingredient information so as to generate nutritional information,
• wherein the service providing apparatus recognizes at least a portion of at least one image including a relevant dish based on augmented reality, determines an area of the relevant dish based on the at least one image realized in the augmented reality, displays a grid on the relevant image, determines an area of each dish included in the relevant image based on a size of the grid, and automatically performs a correction on the displayed grid based on a deviation in width and height of the grid,
• wherein the service providing apparatus:
• determines, based on the corrected grid, a corrected area of the relevant dish;
• classify, based on the determined corrected area of the relevant dish, a type of the relevant dish;
• confirms, based on the classified type of the relevant dish, a size and a volume of the relevant dish;
• corrects, based on the confirmed size and volume of the relevant dish, the weight information of the at least one food;
• and
• generates, based on the corrected weight information of the at least one food, the nutritional information of the at least one food, and
• wherein the service providing apparatus comprises a memory storing database of the pre-stored food information, and repeatedly learns a learning model based on the stored database, by using the at least one image and the generated nutritional information.
