Description

Technical Field

[0001] The present invention belongs to the field of computing technology, and specifically relates to general image data processing, and in particular to a scar image processing system, a patch preparation system and a processing method. Background Art

[0002] Scars need to be covered with patches to treat them. Patches used in some special treatment scenarios contain radioactive liquid medicine, so the size of the patch needs to be adapted to the scar to reduce the impact of the liquid medicine on other normal skin. In the preparation process of the patch in the related technology, errors occur in the image recognition process due to the influence of scar position, that is, there are curvatures in positions such as the arms, and the edges of the image will be distorted when the image of the scar is directly taken, etc., resulting in errors in the scar edge in image recognition, resulting in the final prepared patch being unable to adapt to the scar.

[0003] Therefore, due to the technical problem that scar image recognition has errors caused by the curvature of arms, legs, etc., it is necessary to design a new scar image processing system, patch preparation system and processing method.

[0004] It should be noted that the above information disclosed in this background technology section is only used to understand the background technology of the present application concept, and therefore, the above description is not considered to constitute information of the prior art.

[0012] A pair of cameras in the binocular camera simultaneously captures a human body part image to obtain a human body part image, converts the human body part image by processing the ratio so that the human body part image matches the standard substrate image, and then processes the human body part image by using a distortion parameter so that the standard grid in the human body part image matches the standard grid in the standard substrate image;

[0069] Some embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0070] like Figure 1 As shown, an embodiment of the present disclosure provides a scar image processing system, comprising: a control module, and a shooting module 1 electrically connected to the control module; the shooting module 1 is arranged above a substrate 3, and the shooting module 1 is suitable for shooting an image of the substrate 3 and an image of a human body part on the substrate 3; the control module is configured to obtain distortion parameters of an image according to the image of the substrate 3, and to process the image of the human body part according to the distortion parameters, so as to identify the final scar edge of the scar in the processed image of the human body part; accurate processing of the image is achieved, and the influence of distortion in the image on scar identification is avoided; accurate identification of scars can facilitate accurate preparation of patches and reduce the influence of the patches on normal skin of human body parts.

[0071] During the P32 (phosphorus 32) patch treatment, the requirements of the national "Basic Standards for Ionizing Radiation Protection and Radiation Source Safety" and "Requirements for Nuclear Medicine Radiation Protection" should be followed, and the "radiation protection optimization" and "personal dose limit" basic principles of radiation protection should be implemented. Use image processing methods to produce precise P32 patches to prevent patients from receiving unnecessary abnormal radiation, avoid causing adverse reactions to P32 patch treatment (abnormal radiation of normal skin), and avoid causing side effects.

[0072] like Figure 2 As shown, in an optional embodiment, the shooting module 1 is suitable for using a binocular camera to detect the distance between the shooting module 1 and the shooting object during the image shooting process; the binocular camera includes two cameras, and although the two cameras shoot separately, the image output by the shooting module 1 is one, that is, the images taken by the two cameras are processed into one image; the shooting module 1 can be set on a three-axis moving mechanism 2 to facilitate the movement of the shooting module 1 to meet different shooting needs.

[0073] like Figure 3 and Figure 4As shown, in an optional embodiment, the control module is configured to obtain the distortion parameters of the image according to the image of the substrate 3, including: constructing a coordinate system, that is, taking a corner of the top surface of the substrate 3 as the origin O, the length direction of the top surface of the substrate 3 as the X-axis, the width direction of the top surface of the substrate 3 as the Y-axis, and the direction perpendicular to the top surface of the substrate 3 as the Z-axis; the top surface of the substrate 3 is distributed in a grid shape, the grid is black or white, and the colors of adjacent grids are different, which is convenient for identification after image capture; a preset number of grids around the center point of the top surface of the substrate 3 are standard grids; after the coordinate system is constructed, it is convenient to subsequently splice all images into a plane and identify the complete scar edge in the plane; the grid of the substrate 3 can be used as a reference to better identify the actual size of the area enclosed by the final scar edge, which is convenient for the subsequent accurate preparation of the patch.

[0074] In an optional embodiment, the control module is configured to obtain the distortion parameters of the image according to the image of the substrate 3, and further includes: a pair of cameras in the binocular camera simultaneously capture the image of the substrate 3, and the images captured by the two cameras are constructed as a substrate image; and the binocular camera obtains the standard distance between it and the substrate 3 at this time; the standard grid in the substrate image is compared with the standard grid in the standard substrate image to obtain the distortion parameter, that is, the standard grid in the substrate image is matched with the standard grid in the standard substrate image after the distortion parameter is converted; the edge will be distorted during the image shooting process, and the closer to the center of the image, the lower the degree of distortion; such as Figure 5 and Figure 6 As shown, each image can be divided into a nine-square grid, a 16-square grid, etc. The standard grid of the nine-square grid can be the center grid (i.e. the shaded part in the figure), the 16-square grid can be the four middle grids, etc., the grid where the center point of the image is located, or a circle of grids around the center point of the image, etc.

[0075] In an optional embodiment, the processing of the image of the human body part according to the distortion parameters includes: after obtaining the distortion parameters, photographing the human body part to obtain the image of the human body part, that is, moving the human body part with the scar to the substrate 3, photographing the human body part through a binocular camera to obtain the image of the human body part, the human body part moves to a first position on the substrate 3 as a basic position, and then the human body part moves along the positive direction and / or negative direction of the Y-axis, each time it moves a preset distance, each time the human body part moves it will be recorded as a corresponding position, the human body part will rotate at each position, each time it rotates a preset angle, and each rotation will photograph the human body part; due to the curvature of the human body part, etc., the shooting module 1 cannot completely include the scar in one shot. For example, if there is a scar on the arm, due to the long length of the arm and the scar may be from the front of the arm to the back. The scar is extended to the back of the arm, so that the shooting module 1 cannot completely include all the scar parts in one shot. Therefore, the arm is first moved to the substrate 3, and the first position is recorded as the basic position. At this time, the shooting module 1 takes a picture, and then the arm is rotated at a preset angle (such as 10 degrees counterclockwise) at the basic position and then photographed again until the arm is fully rotated 180 degrees. After the arm returns to the basic position, it is rotated in the other direction (the first rotation direction is counterclockwise and the second rotation direction is clockwise) until it is rotated 180 degrees. The two rotations allow the arm to fully rotate 360 ​​degrees. After the basic position shooting is completed, the arm can be moved to shoot the next position. Since the arm is long, it needs to be moved and rotated to ensure that the image formed by subsequent splicing can fully reflect the various positions of the arm; at the same position, the arm rotates without changing its position, that is, it rotates in place.

[0076] In an optional implementation, during the shooting process, the actual distance between the human body part and the binocular camera is obtained through the binocular camera, the actual distance is compared with the standard distance, and the ratio between the actual distance and the standard distance is obtained, and the ratio is the processing ratio of the human body part image; a pair of cameras in the binocular camera simultaneously shoot the human body part image to obtain a human body part image, and the human body part image is converted by the processing ratio to match the human body part image with the standard substrate image, and then the human body part image is processed by the distortion parameter to match the standard grid in the human body part image with the standard grid in the standard substrate image; due to the height of the arm, the arm image captured by the shooting module 1 and the standard substrate image are at different heights, so firstly the actual distance and the standard substrate image are compared. The ratio between the standard distances processes the arm image to the same size as the standard substrate image, and then processes the arm image through the distortion parameters, so that the standard grid in the arm image is more accurate, which is convenient for the subsequent accurate identification of the edge of the scar; in the above process, the preset distance of movement and the preset angle of rotation of the human body part are calculated by the size of the human body part image that matches the standard grid in the standard substrate image, which can be used to determine whether each movement or rotation of the human body part is accurate, ensuring that each movement and rotation of the human body part is accurate, so that the standard grid of the next human body part image taken can be aligned and spliced ​​with one side edge of the standard grid of the previous human body part image, and after splicing the standard grids of all human body part images, a complete scar image can be obtained to identify the final scar edge of the scar.

[0077] like Figure 7 and Figure 8As shown, in an optional embodiment, the substrate 3 is provided with a supporting mechanism 4 on both sides along the Y-axis direction, wherein the supporting mechanism 4 includes: a bottom plate 41, a linear motor 42 and a supporting plate 43; the length direction of the linear motor 42 is parallel to the Y-axis direction, and the linear motor 42 is arranged on the bottom plate 41; a first servo motor 44 is arranged on the linear motor 42, and the first servo motor 44 is connected to the bottom surface of the supporting plate 43, and the first servo motor 44 is electrically connected to the control module; the linear motor 42 is electrically connected to the control module; the supporting plate 43 is arc-shaped to support human body parts, and a binding is arranged on the top surface of the supporting plate 43 The strap 45 is suitable for fixing the human body part; the control module controls the first servo motor 44 to drive the supporting plate 43 to rotate so that the human body part rotates; the control module controls the linear motor 42 to drive the supporting plate 43 to move so that the human body part moves along the Y-axis direction; when it is necessary to drive the human body part to move and rotate, the human body part is first moved to the supporting plates 43 of the two supporting mechanisms 4. At this time, the part of the human body part with the scar is between the two supporting plates 43 and above the substrate 3 to avoid the supporting plate 43 blocking the scar. At this time, the two positions on the human body part are fixed to the corresponding supporting plates 43 by the strap 45 to avoid the human body part relative to the supporting plate 43. The support plate 43 moves to facilitate the precise rotation of the human body part. The human body part can be an arm, that is, two positions on the arm are fixed to the corresponding support plate 43 through straps 45, and the arc-shaped support plate 43 can adapt to the shape of the arm so that the arm can be better fixed. After the human body part is fixed, the corresponding support plate 43 is driven to move by the linear motor 42. The two linear motors 42 work synchronously to make the two support plates 43 move synchronously and in the same direction, driving the human body part to move a precise distance along the positive or negative direction of the Y-axis. The precise control of the control module and the precise movement of the linear motor 42 can realize the precise control of the moving distance of the support plate 43, as well as the precise rotation of the human body. When a body part needs to be rotated, the corresponding support plate 43 is driven to rotate by the first servo motor 44, and the two support plates 43 rotate synchronously in the same direction and at the same angle. The control module can control the angle of rotation of the support plate 43 driven by the first servo motor 44, so that each rotation angle is accurate and meets the preset angle; long rollers 46 can be set on both sides of the linear motor 42, and the length direction of the rollers 46 is parallel to the length direction of the linear motor 42. The rollers 46 are in contact with the bottom surface of the support plate 43. The rollers 46 can be set above the top surface of the bottom plate 41 through the stand 47. The rollers 46 are rotatably connected to the stand 47. During the rotation of the support plate 43, the rollers 46 can assist the support plate 43 in rotating.

[0078] The processed human body part images are cropped so that the standard grids in the processed human body part images are retained; each human body part image is cropped to obtain the standard grid of each human body part image, and the standard grids of all human body part images are arranged and spliced, that is, the standard grid of the human body part image at the basic position is taken as the center position, and the standard grid of the first human body part image corresponding to the position after the human body part moves along the positive direction of the Y axis is spliced ​​above the center position, and the standard grid of the first human body part image corresponding to the position after the human body part moves along the negative direction of the Y axis is spliced ​​below the center position, and the standard grids in the human body part image taken after the rotation angle at each position are spliced ​​on one side of the first human body part image standard grid at the position along the X-axis direction, and the edges of adjacent standard grids overlap to obtain a complete plane image of the human body part; the image after the clockwise rotation angle is spliced ​​on the left side of the first image at each position, and the image after the counterclockwise rotation angle is spliced ​​on the right side of the first image at each position, and all the cropped standard grids are spliced ​​to form a complete plane image of the human body part.

[0079] In an optional embodiment, the control module is further configured to identify the edge of the scar in the complete plane image of the human body part, add a preset error thereto after identifying the scar edge, and obtain a final scar edge; after adding the preset error-free error, the final scar edge will be larger than the edge of the scar identified in the complete plane image, so that the subsequently prepared patch can completely cover the actual scar; identify the area of ​​the region enclosed by the final scar edge, that is, the area of ​​the scar area. If the area is too large, it needs to be cropped, that is, the area of ​​the entire scar area is obtained. The patch has a maximum usage area when used, for example, not more than 200 square centimeters for adults and not more than 100 square centimeters for infants and young children, to prevent systemic reactions. If it exceeds, the final scar edge is cropped, and the scar area is divided into multiple parts, so that the area of ​​each part meets the requirements, and only one part is prepared each time when the patch is prepared subsequently, and only one part of the patch is used on the human body each time.
