Abstract

The invention discloses a diet nutrition management method and system for chronic disease patients, and relates to the technical field of healthy diet nutrition management. The method comprises the following steps: collecting daily diet pictures of various chronic disease patients to form a diet picture library; preprocessing the diet picture to obtain a diet target label set and a food material segmentation label set; respectively training a diet target detection model and a food material segmentation model by using the diet picture, the diet target label set and the food material segmentation label set; sequentially connecting the diet target detection model and the food material segmentation model in series into the system, enabling the diet picture of the target user to sequentially pass through the diet target detection model and the food material segmentation model, and finally outputting a plurality of pixel-level food material segmentation pictures; performing perspective restoration on each food material segmentation map; calculating the ratio of nutrient elements contained in all food materials in the diet picture of the target user based on the food material segmentation map; and personalized diet suggestions are made. According to the invention, accurate diet suggestions can be provided for the user, and the user compliance is improved at the same time.
