Abstract
Description
Technical Field
[0001] This invention relates to the field of medical and nursing technology, and more specifically to a method, apparatus, device, and readable storage medium for creating a dietary chart. Background Technology
[0002] Poor dietary habits are common among stroke patients, and intervening in these habits can effectively reduce the risk of stroke recurrence and is of great significance in changing patients' clinical outcomes.
[0003] Conducting dietary surveys requires participants to have a certain level of calculation and literacy skills. Weighing or estimating the total amount of food consumed is a challenging task. Most participants' estimations of daily food intake remain at a rather crude level, making it difficult to accurately estimate the amount of food consumed and reduce the error in food intake estimation. Traditional dietary survey methods include accounting methods, dietary history methods, chemical analysis methods, dietary frequency surveys, 24-hour dietary recall methods, and internet-based dietary records. Accounting methods can only investigate the dietary consumption of families or groups, making it difficult to accurately investigate individual diets. Chemical analysis methods, also known as nutrient analysis, involve preparing two identical portions of food. One portion is consumed by the research subject, while the other is used as a food sample to determine its nutrient composition. This method is costly and complex, and therefore rarely used. The 24-hour dietary recall method, which records a researcher's food intake over the past 24 hours, significantly underestimates the researcher's total dietary intake. Retrospective questionnaires also have a time lag, leading to memory and experience biases. Stroke patients' memory impairment and other medical conditions can amplify recall bias in retrospective questionnaires. Existing online dietary recording methods, such as "Mint Health," offer shorter time intervals compared to retrospective questionnaires, potentially improving accuracy. However, these tools mostly require patients to manually input their total food intake, lacking portion size references to help patients accurately assess food portions. The discrepancy between the reported total intake and actual intake is significant, indicating limitations in functionality and accuracy.
[0004] Therefore, there is an urgent need for a method for creating dietary charts that can overcome the above-mentioned shortcomings. Summary of the Invention

[0033] The above description is merely an overview of the technical solution of the present invention. In order to better understand the technical means of the present invention and to implement it in accordance with the contents of the specification, the preferred embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0038] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0039] It should be noted that references to "an embodiment," "embodiment," "example embodiment," etc., in this specification refer to the described embodiment including specific features, structures, or characteristics; however, not every embodiment must include these specific features, structures, or characteristics. Furthermore, such expressions do not refer to the same embodiment. Moreover, when describing specific features, structures, or characteristics in conjunction with embodiments, whether or not explicitly described, it is indicated that incorporating such features, structures, or characteristics into other embodiments is within the knowledge of those skilled in the art.
[0040] Furthermore, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.
[0041] In some embodiments, such as Figure 1 The diagram shows a flowchart of a method for creating a dietary atlas, the specific method including:
[0042] S101, Obtain candidate foods, and for each candidate food, divide the candidate food into several portions of different quality.
[0043] The candidate foods are common local foods, such as grains, vegetables, and fruits.
[0044] For example, when the candidate food is rice, the rice can be divided into three portions of different sizes.
[0045] Optionally, different body types can be selected for each candidate food.
[0046] For example, when the candidate food is apples, three apples of different sizes can be selected.
[0047] S102, Weigh several candidate food samples to obtain the mass of each candidate food sample.
[0048] For example, when the candidate food is rice, three portions of rice are weighed, for example, the weights of the three portions of rice are 100 grams, 200 grams, and 300 grams respectively; when the candidate food is apples, three apples of different sizes are weighed, for example, the weights of the three apples are 80 grams, 100 grams, and 120 grams respectively.
[0049] S103, based on the quality of each candidate food, arrange each candidate food in order of its weight on the target background plate with scale.
[0050] The target background board also includes reference objects, which are usually common items such as beverage bottles.
[0051] Optionally, each candidate food can be arranged in order of size on a graduated target background board.
[0052] For example, when the candidate food is an apple and the reference is a beverage bottle, each apple and the reference can be arranged in order of apple size onto a graduated background board with graduations accurate to the millimeter. This way, when patients use the final generated atlas, they have both graduations and references to refer to, enabling them to more accurately grasp the amount of food.
[0053] Optionally, before arranging each candidate food item in order of weight and size on the graduated target background board, the target background board can be selected from candidate background boards of different colors based on the color of the candidate food items.
[0054] For example, when the food is a light-colored food like rice, a black background can be selected as the target background; when the food is a dark-colored food like apples, a white background can be selected as the target background. This increases the contrast between the food and the background, making it easier for users to assess the amount of food.
[0055] S104, take a picture of the target background board on which candidate foods and reference objects are placed to obtain a background board image, and generate a dietary atlas based on the background board image.
[0056] Specifically, after placing the candidate food and reference objects on the target background board, the entire target background board is photographed using a camera to obtain the background board image, which can be directly used as a dietary atlas.
[0057] Optionally, a joint recognition algorithm of edge detection and color clustering can be used to identify a first region and a second region from the background image; the first region is the region where the candidate food is located, and the second region is the background region corresponding to the first region; the quality of the candidate food in the first region is marked in the second region to obtain a labeled image; and the dietary atlas is generated based on the labeled image.
[0058] Specifically, the background image can be divided using Canny edge detection and K-means clustering algorithms to obtain a first region containing candidate foods and a second region corresponding to the first region. The second region is usually located below the first region. The quality of each candidate food in the first region can be labeled in the second region, thus obtaining a labeled image. The labeled image can be directly used as a dietary atlas. Since the dietary atlas contains the quality of each food, it is easier for users to evaluate their own recipes.
[0059] Optionally, the labeled images can be printed as physical dietary charts and / or electronic dietary charts can be generated based on the labeled images.
[0060] Specifically, according to user needs, the labeled images can be printed as physical dietary charts. Some users may use their mobile phones to view the dietary charts, so electronic dietary charts can be generated based on the labeled images.
[0061] The dietary atlas creation method in the above embodiments involves first acquiring candidate foods, then dividing each candidate food into several portions of varying weights; weighing each portion to obtain its mass; arranging each portion of candidate food in order of mass onto a graduated target background board; a reference object is also placed on the target background board; photographing the target background board with the candidate foods and reference object to obtain an image of the background board, and generating a dietary atlas based on the image. By placing the food, background board, and reference object together to create a dietary atlas, patients can accurately determine their daily food intake based on the dietary atlas, thereby helping them recover quickly.
[0062] To more comprehensively demonstrate this solution, this embodiment provides an optional method for creating a dietary atlas, such as... Figure 2 As shown:

[0065] S202, Weigh several candidate food samples to obtain the mass of each candidate food sample.
[0066] S203, Select a target background board from candidate background boards of different colors according to the color of the candidate food.
[0067] S204, based on the quality of each candidate food, arrange each candidate food in order of its weight on the target background plate with scale.
[0068] Optionally, based on the size of each candidate food item, the candidate foods are arranged sequentially on a graduated target background board. The target background board also includes reference objects.
[0069] S205, take a picture of the target background board on which candidate food and reference objects are placed, and obtain the background board image.
[0070] S206, using a joint recognition algorithm of edge detection and color clustering, the first region and the second region are identified from the background image.
[0071] S207, mark the quality of the candidate food in the first region in the second region to obtain a marked image.
