Description

[0001] The present invention relates to a nutrition analyzing system for dietary diets,

According to the present invention, a food plate is divided into a plurality of food-containing portions, and when the plate is placed on a measurement table, the foods contained in the plate are picked up multiple times, the weight of the food contained in each food-containing portion is measured, , And nutrition analysis system for diary.

In general, the eating habits for proper nutrient intake and calorie control are the most basic ones to protect physical health, but due to the increase in the nuclear family and the social activities of women, eating habits are changed and eating habits become unfavorable. Obesity, diabetes, hypertension And various lifestyle-related diseases such as a disease are becoming a problem.

Therefore, it is very important to investigate the eating habits and activity habits of the individual in relation to the nutritional status analysis of the subject, the correction of lifestyle, and the improvement of diseases such as obesity, diabetes and hypertension. Through the analysis of eating habits, you can see the foods you usually enjoy, the nutrients you eat a lot, the nutrients you lack, and the total amount of calories consumed. In addition, it is possible to judge whether the balance between the calories consumed through meals and the calories consumed through activities. Physicians, nutritionists, and exercise prescribers can use the results of these analyzes to improve their eating habits and to prescribe meals and exercise prescriptions that can supplement deficient activities or exercises.

In the investigation of these eating habits, the existing methods have been mostly utilized by one-on-one counseling or using questionnaires. One-on-one counseling was a form in which the patient's diet and activity habits were interviewed by a nurse or doctor directly in front of the patient, but it was difficult to be meticulously and precisely realistic in terms of time constraints.

Due to this difficulty, a method of providing a predetermined form of diary questionnaire to the patient in advance and filling it out in advance was used. The meal diary form is a table in which the date, the day of the week, and the meal are separated, and the contents of the meal corresponding to the date, day of week, and meal are directly written by the subject or recorded using the application [ 2].

However, the method using the questionnaire can be described freely and can be actual and accurate, but conversely, it may be expressed without restriction, resulting in subjective judgment of the amount of intake, unspecified delivery of food names or activities. In addition, the user has a burden of recording meal diary or meal information for every meal. In other words, since it is cumbersome to record the meal information every meal, there are many cases where a meal diary is abandoned in the middle. Therefore, it is very difficult to perform continuous and periodic monitoring of meals.

To this end, techniques for automatically calculating food items in a plate using a camera or a weight sensor have been proposed [Patent Documents 3, 4, 5]. However, the above prior art analyzes the food contained in the plate using only the camera or only the weight sensor. Therefore, it is difficult to accurately determine the amount or type of food contained in the plate.
