[0037] It should be further understood that the term "and / or" used in the present description and the appended claims refers to any and all possible combinations of one or more of the associated listed items, and includes these combinations.

[0038] Reference Figures 1 to 4 As shown, an embodiment of the present application provides a data visualization method for a light therapy device, which may include the following steps:

[0039] S100: Acquire a first lesion skin region and a second lesion skin region, wherein the first lesion skin region is acquired at a previous moment, and the second lesion skin region is acquired at a later moment.

[0040] In this embodiment, the first lesion skin lesion area is the area occupied by the skin lesion of the lesion area obtained in the previous treatment, the previous moment is the time point of the previous treatment, the second lesion skin lesion area is the area occupied by the skin lesion of the lesion area obtained in the later treatment, and the later moment is the time point of the later treatment. By obtaining the area occupied by the skin lesion, the pathological condition of the patient's lesion area can be reflected very intuitively, and by obtaining the lesion area at least twice or more at different treatment time nodes, multiple comparison groups with time as the first variable can be formed for patients or medical staff to observe and obtain pathological information.

[0041] In one embodiment, referring to Figure 2 The step of obtaining the first lesion area includes:

[0042] S110: Acquire a first skin lesion image;

[0043] S120: Obtain a first skin lesion area based on the pixels corresponding to the first skin lesion image.

[0044] In the present embodiment, the skin lesion picture refers to an image file reflecting the condition of the lesion area of ​​a skin disease patient obtained by photographing a photographic device or a phototherapy device with a photographic device. When photographing using a photographic device or a phototherapy device with a photographic device, in order to make the photographed file meet the needs of subsequent use so as to calculate the skin lesion area, it is necessary to shoot according to some standards, including selecting the photographing area and adjusting the angle of the photographing by artificially preset or by software calculated reference standards. In order to enhance the expressiveness of imaging, it is usually necessary to fill in the light before taking pictures, or for some special pathological conditions, it is necessary to use special lighting to illuminate the lesion area after imaging so as to make it easier to distinguish, for example, for the vitiligo lesion area, normal skin is pale white or grayish white under ultraviolet light, while the lesion part of the vitiligo lesion area is porcelain white under ultraviolet light, and the boundary is clear, so it is usually necessary to supplement with ultraviolet light when taking the skin lesion pictures of vitiligo patients so as to obtain the best picture of the lesion area condition. After obtaining the first skin lesion image, it is possible to distinguish whether a certain pixel in the image represents a lesion area based on the color number of the pixel corresponding to the first skin lesion image. Since the colors presented by normal skin and lesion skin are different, the pixel points representing normal skin and the pixel points representing lesion skin can be divided according to the color number range of the pixel points in the image, and then the number of pixel points representing lesion skin is counted, combined with the total number of pixels in the entire image, and finally the first lesion skin lesion area is calculated.

[0045] In particular, since the images captured by the camera itself are two-dimensional images, for skin areas with larger curvature on the human body, such as arms and legs, the two-dimensional images captured at a single area position cannot accurately reflect the patient's entire skin lesion condition. Therefore, for skin areas with larger curvature, image processing and splicing will be performed after taking the picture, and the software will be calibrated to obtain a skin lesion image that can fully reflect the patient's entire skin lesion condition, and then the corresponding diseased skin lesion area will be calculated based on the pixels corresponding to the skin lesion image.

[0046] In one embodiment, referring to Figure 3 The step of calculating the first skin lesion area based on the pixels corresponding to the first skin lesion image comprises:

[0047] S121: Processing the first skin lesion image according to pixels to generate a first grid image;

[0048] S122: grayscale the first grid image so that the lesion area appears bright white and the non-lesion area appears dark;

[0049] S123: Calculate the size of the first lesion area according to the number of bright white pixels.

[0050] In this embodiment, the grid image refers to an image file in which each pixel or pixel matrix is ​​divided by longitude and latitude in the image, and the lesion area refers to an area composed of continuous pixels or pixel matrix that can represent the diseased skin, and the non-lesion area refers to an area composed of continuous pixels or pixel matrix that can represent normal skin. The first skin lesion image is gridded according to the pixels, and the longitude and latitude arranged in the horizontal and vertical directions are given to the image to generate the first grid image. The pixels are digitized by the gridded file to facilitate recording the position and color attributes of each pixel or pixel matrix. Then the first grid image is grayscale processed so that the lesion area is bright white and the non-lesion area is dark. After the grayscale processing is two-colorized, the number range of colors carried by the image to be subsequently calculated for area is reduced. For example, the colors carried by the pixels carried by the original image include sixty-four colors, and after the above adjustment, there are only 16 colors, which reduces the calculation difficulty for the computer to determine whether the color carried by the pixel represents the skin of the lesion area or the normal skin, and improves the processing efficiency. Afterwards, since it is known that the lesion area is bright white, the size of the first lesion skin lesion area can be calculated based on the number of pixels showing bright white.

[0051] In one embodiment, referring to Figure 2 The step of obtaining the second lesion area includes:

[0052] S130: Drawing the upper, lower, left, and right edges of the first skin lesion image to generate edge boundaries;

[0053] S140: Identifying the lesion skin boundary based on the pixels corresponding to the first skin lesion image and drawing to generate a lesion boundary line;

[0054] S150: generating a positioning frame according to the edge boundary and the lesion boundary line;

[0055] S160: photographing a second skin lesion image using the positioning frame;

[0056] S170: Obtain a second skin lesion area based on the pixels corresponding to the second skin lesion image.

[0057] In this embodiment, the edge boundary refers to the overall reference obtained by drawing the border of the skin lesion image, the lesion boundary line refers to the boundary depiction of the area composed of continuous pixel points that only appear as lesion skin in the skin lesion image, as a reference for the shape and position of the lesion area, and the positioning frame refers to the reference information that provides the positioning basis for the photographic device or the phototherapy device with a photographic device when the next skin lesion image is obtained. As the treatment progresses and time changes, the skin in the lesion area will also change, including the curvature of the skin, the area and shape of the lesion area, or new lesion areas may be generated. Therefore, in order to make each skin lesion image obtained fully reflect the lesion area status during the current treatment, and to make the comparison of the lesion skin lesion area calculated from multiple skin lesion images more accurate, it is necessary to rely on each skin lesion image obtained to update the positioning information of the photographic device or the phototherapy device with a photographic device when shooting. By drawing the upper, lower, left and right edges of the skin lesion image to generate edge boundaries, a reference can be obtained, and then the pixels corresponding to the skin lesion image are identified to obtain the lesion skin boundary and draw to generate the lesion boundary line to obtain another reference. The shape and position relationship between the above two references can be used to confirm the positioning frame of the re-positioning information of the photographic device or the phototherapy device with a photographic device during the next shooting. In actual operation, the edge boundary is generally used to determine the boundary of the photographic device or the phototherapy device with a photographic device during shooting, so as to avoid that some lesion area skin is not photographed, and the lesion boundary line is the accurate positioning of the lesion area in the picture, so as to ensure that the angle of the photo, the degree of illumination and the clarity of the photo are as small as possible from the previous time, so that the final skin lesion image is fully representative. In the subsequent treatment, the next skin lesion image is obtained by shooting through the above positioning frame, and then the corresponding lesion skin lesion area is calculated based on the pixels corresponding to the skin lesion image. After multiple treatments, multiple lesion skin lesion areas obtained at different times can be obtained.

[0058] S200: Aligning the contours of the first lesion area with the second lesion area, and comparing the sizes of the first lesion area with the second lesion area to determine a skin recovery score;

[0059] In this embodiment, the skin recovery score refers to a score used to evaluate the treatment effect. Since the first lesion area and the second lesion area are obtained under different conditions, the contours must be aligned by changing the size or rotating them to make them comparable, and then a ratio score can be obtained by comparing the sizes of the first lesion area and the second lesion area. The ratio score is defined as the skin recovery score to evaluate the effect of skin phototherapy.

[0060] In one embodiment, referring to Figure 4 The step of aligning the contours of the first lesion area and the second lesion area comprises:

[0061] S210: establishing reference coordinates according to the first lesion area;

[0062] S220: Align the second lesion area with the reference coordinates.

[0063] In this embodiment, a reference coordinate is established for the first lesion area, so that a reference is provided for the alignment of the second lesion area acquired subsequently. The specific reference coordinate established will vary according to the shape and position of the first lesion area. After acquiring the second lesion area, it is aligned with the above-mentioned reference coordinate, and the contour alignment of the first lesion area and the second lesion area can be completed.

[0064] In one embodiment, referring to Figure 4 The step of comparing the sizes of the first lesion area and the second lesion area to determine the skin recovery score comprises:

[0065] S230: assigning an initial score according to the first lesion area;

[0066] S240: comparing the area difference between the first lesion area and the second lesion area;

[0067] S250: Adjust the initial score according to the area difference to determine a skin recovery score.

[0068] In this embodiment, the initial score refers to a benchmark score that reflects the condition of the lesion area at the beginning of treatment or the last treatment. The initial score is assigned according to the first lesion area, and the area difference between the first lesion area and the second lesion area is compared. The initial score is adjusted according to the area difference to determine the skin recovery score. In actual use, the lesion area may have many complex situations. For example, its distribution may be scattered and unconcentrated, or the lesion area may be in contact with the scar, which will affect the comparison. Therefore, the software will be used to segment the lesion area and classify and assign points, so that the subsequent calculation of the area difference is more accurate. When the area of ​​the lesion area is reduced after treatment, the initial score will be increased to obtain a better score to reflect the good treatment effect.

[0069] S300: Summarize and visualize the skin scores to generate a visualization image.

[0070] In this embodiment, the visual image refers to an image such as a table, a line graph or a bar graph that can be intuitively viewed and understood by the patient or medical staff, so that the patient or medical staff can quickly understand the effect of the treatment. After obtaining multiple skin recovery scores, a visual chart or image with the skin recovery score of each time as the vertical axis can be generated with time or the number of treatment sequences as the horizontal axis. Through these charts or images, patients can clearly understand the treatment status of their phototherapy, which makes it easier to understand their own symptoms and boost their confidence to persist in treatment.

[0071] Through the present invention, the treatment results achieved after treatment can be more clearly displayed to the user, allowing the user to more conveniently understand the therapeutic effect of phototherapy on the lesion area, thereby reducing the difficulty for the user to understand the efficacy of phototherapy.
