System and method for measuring dish size and providing nutrition information using image recognition and augmented reality based on artificial intelligence

A system for measuring dish size and providing nutritional information using image recognition and augmented reality based on 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 the at least one dish and the at least one food from the at least one image when the at least one image is received, confirming the name of each detected food on the basis of a learning model, predicting the size of each detected dish, predicting the volume of each detected food using the predicted size of the dish, and generating nutritional information using the predicted volume of each food and pre-stored food information;
• and
• a user terminal for visualizing and displaying the nutritional information when the nutritional information is received,
• wherein the size of each detected dish is predicted obtained using any one among a first method and a second method, the first method is a method of realizing and using the at least one image in augmented reality, and the second method is a method of detecting and using at least one bounding box from the at least one image.
