[0040] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field based on the present application belong to the scope of protection of the present application.

[0041] First, some professional terms in the embodiments of the present application are briefly introduced:

[0042] Binocular camera calibration file: A reference file for restoring the world's 3D coordinate system based on images. It can also be considered as a reference file for converting image coordinates into coordinates in the world's 3D coordinate system.

[0043] Binocular camera: A camera module with the same specifications and parameters. A binocular camera can contain two cameras.

[0044] Distortion correction: used to restore geometrically distorted images to normal state.

[0045] And, in order to better understand this solution, the following introduces the relevant technologies:

[0046] Based on a single camera taking an image containing a pressure sore, image recognition is performed on the image to identify the size information of the pressure sore in a three-dimensional coordinate system. However, in the process of image recognition, it is easily affected by the surrounding environment, resulting in inaccurate size information of the pressure sore. For example, when the angle of taking a picture of the pressure sore is crooked, the size information of the pressure sore may be inaccurate. In addition, only referring to a single image to calculate the size information of the pressure sore will also result in low accuracy in detecting the size information of the pressure sore.

[0047] Based on the problems described above, the embodiments of the present application provide a pressure ulcer measurement method, device, medical detection equipment and storage medium.

[0048] The following is an introduction to the pressure sore measurement method provided in the embodiments of the present application.

[0049] Among them, the pressure sore measurement method provided in the embodiment of the present application can be applied to medical detection equipment, which can also be called an all-in-one device. The medical detection equipment can be a device that includes at least a first camera, a second camera and a display screen. Of course, the medical detection equipment can also include other devices, such as: a QR code scanning unit, which is not specifically limited in the embodiment of the present application; in one implementation method, the medical detection equipment can be a handheld device, such as: a mobile phone device, a tablet computer device, etc. Of course, the medical detection equipment can also be a non-handheld device, which is not specifically limited in the embodiment of the present application.

[0050] In addition, the first camera and the second camera of the medical detection equipment can be two cameras of a binocular camera, that is, the medical detection equipment can include a binocular camera, and the two cameras in the binocular camera can be used as the first camera and the second camera in this application; exemplarily, the first camera can be considered as the camera of the left camera in the binocular camera, and the second camera can be considered as the camera of the right camera in the binocular camera, and the embodiment of the present application does not make specific limitations on this; any binocular camera on the market can be used as the binocular camera in the embodiment of the present application.

[0051] The following is a brief introduction to the application scenarios of the pressure sore measurement method provided in the embodiment of the present application:

[0052] The application scenario of the embodiments of the present application may be a medical photography scenario. For example, the medical photography scenario may be a scenario in which medical staff and other operators photograph a patient's pressure sores for archiving, or a scenario in which medical staff and other operators photograph a patient's pressure sores for inspection and analysis, and so on.

[0053] Among them, a method for measuring pressure sores is applied to a medical detection device, the medical detection device at least comprising a first camera, a second camera and a display screen, the first camera and the second camera having overlapping fields of view; the method comprises:

[0054] Turning on the first camera and the second camera;

[0055] Acquire a collection picture of the target detection area, and display the collection picture of the target detection area on the display screen; wherein the target detection area is the overlapping field of view range, and the pressure sore to be detected is located in the target detection area;

[0056] Acquire an image containing a target acquisition screen to obtain a target image; wherein the target acquisition screen is a capture screen of the target detection area by a designated camera, and the designated camera is one of the first camera and the second camera;

[0057] Determine a plurality of target marking points in the target image; wherein the plurality of target marking points are used to indicate location points of pressure sores within the target detection area;

[0058] Based on the multiple target marking points, the size of the pressure sore is calculated to obtain size information of the pressure sore.

[0059] It can be seen that the pressure sore measurement method provided in the embodiment of the present application does not require manual measurement when detecting the size information of the pressure sore, does not need to consume a lot of time, greatly saves human resources, and can improve the efficiency of pressure sore detection; and the embodiment of the present application can simultaneously turn on the first camera and the second camera of the medical detection equipment, and can ensure the synchronization of the images collected by the first camera and the second camera (that is, ensure the imaging synchronization). In theory, the delay between the first camera and the second camera for imaging can reach 0ms, thereby improving the accuracy of pressure sore detection.

[0060] A method for measuring pressure sores provided in an embodiment of the present application is described below in conjunction with the accompanying drawings.

[0061] like Figure 1 As shown, a pressure sore measurement method provided in an embodiment of the present application is applied to a medical detection device, wherein the medical detection device comprises at least a first camera, a second camera and a display screen, wherein the first camera and the second camera have overlapping fields of view; the method comprises:

[0062] S101, turning on the first camera and the second camera;

[0063] It is understandable that when the medical detection device is started, or when an instruction to turn on the first camera and the second camera is detected, the medical detection device can turn on the first camera and the second camera, and the embodiment of the present application does not specifically limit the conditions for turning on the first camera and the second camera. In addition, when the camera of the medical detection device is turned on, the first camera and the second camera can be turned on at the same time.

[0064] Exemplarily, in one implementation, the step of starting the first camera and the second camera includes step A1:

[0065] Step A1, in response to an opening instruction for a target logical camera, determining the physical ID to which the target ID of the target logical camera is mapped from a pre-established mapping relationship, and controlling each camera having the determined physical ID to be opened simultaneously;

[0066] The pre-established mapping relationship is established in the following manner:

[0067] A mapping relationship is established between the physical ID of the first camera, the physical ID of the second camera and the target ID.

[0068] The target logic camera is a logic camera obtained after packaging the first camera and the second camera;

[0069] It can be understood that each sensor senor on the medical detection device can be mapped to a senor ID (Identity document). Then, the first camera and the second camera of the medical detection device can both be used as a sensor, and thus can be mapped to a camera ID. In this way, each camera is mapped to a camera ID, and the camera ID can also be called a physical ID or a physicalCamera (physical camera) ID; then, the first camera and the second camera can be packaged to obtain a logical camera, that is, a target logical camera, so the physical ID of the first camera and the physical ID of the second camera can also establish a mapping relationship with the ID of the logical camera, and the ID of the logical camera can also be called a target ID, or a logicalCamera (logical camera) ID; illustratively, the physical ID of camera 1 is 2, and the physical ID of camera 2 is 4. Cameras 1 and 2 can be packaged to obtain a target logical camera, and the target ID of the target logical camera is 5. In addition, the medical detection device can control the first camera and the second camera to start at the same time through the mapping relationship between the target ID and the physical ID, and obtain the preview images collected by the first camera and the second camera. The collected preview images are completely synchronized without any delay. Exemplarily, when the medical detection equipment is an Android device, the camera device (cameraDevice) of the Android device can be turned on by controlling the target logical camera, thereby controlling the first camera and the second camera to be turned on at the same time, and obtaining the preview images captured by the first camera and the second camera. The captured preview images are completely synchronized without any delay.

[0070] It is understandable that the medical detection device can be turned on by controlling the target logical camera, responding to the turn-on instruction of the target logical camera, determining the physical ID to which the target ID of the target logical camera is mapped based on the mapping relationship between the physical ID of each camera and the target ID, and controlling each camera with the determined physical ID to be turned on at the same time based on the physical ID, thereby realizing the simultaneous turning on of the first camera and the second camera. In this process, there is a 0ms delay between the first camera and the second camera, thereby ensuring the accuracy of the detection of pressure sores. Exemplarily, the target ID of the target logical camera is 5, and the physical IDs of the first camera and the second camera are 2 and 4 respectively. A mapping relationship between 5 and 2 and 4 can be established, thereby, responding to the turn-on instruction of the turn-on instruction of the target logical camera, based on the target ID of the target logical camera (i.e., 5) and the mapping relationship, the first camera and the second camera are determined, and the first camera and the second camera are controlled to be turned on at the same time.

[0071] It can be seen that the embodiment of the present application can pre-establish a mapping relationship between the physical ID of each camera and the target ID. When responding to an on instruction for a target logical camera, the physical ID to which the target ID of the target logical camera is mapped can be determined from the mapping relationship, and each camera with a determined physical ID can be controlled to be turned on at the same time, so that the delay between the first camera and the second camera is 0, thereby ensuring the real-time nature of the captured image and improving the accuracy of pressure sore detection.

[0072] S102, acquiring a captured image of the target detection area, and displaying the captured image of the target detection area on a display screen;

[0073] Wherein, the target detection area is the overlapping field of view, and the pressure sore to be detected is located in the target detection area;

[0074] It can be understood that the first camera and the second camera can also have a preview function. After turning on the first camera and the second camera, the target detection area can be continuously captured, and the captured pictures of the target detection area can be continuously displayed on the display screen; when the pressure sore to be detected is located in the target detection area, the first camera and the second camera can capture images of the target detection area, so that the medical detection equipment can obtain the captured picture of the target detection area, and the captured picture can be captured by the first camera, or by the second camera, or by the first camera and the second camera. The embodiment of the present application does not make specific limitations on this; then, the captured picture of the target detection area captured by any camera can be displayed on the display screen, and the captured pictures of the target detection area captured by the first camera and the second camera can also be displayed on the display screen. The embodiment of the present application does not make specific limitations on this.

[0075] Exemplarily, in one implementation, obtaining a captured image of a target detection area may include step B1:

[0076] Step B1, obtaining a collection picture of the target detection area by the first camera and obtaining a collection picture of the target detection area by the second camera;

[0077] Accordingly, the target acquisition picture is displayed on the display screen, including step C1:

[0078] Step C1, displaying the captured image of the target detection area on the display screen according to a predetermined display method; wherein the predetermined display method includes that the captured image of the target detection area by the designated camera is visible to the user, and the captured image of the target detection area by another camera other than the designated camera is not visible to the user.

[0079] It can be understood that step B1 is for the case of simultaneously acquiring the captured images of the target detection area by the first camera and the second camera. Then, after the first camera and the second camera are turned on at the same time, the two cameras can simultaneously acquire images of the target detection area. At this time, the medical detection equipment can acquire the captured images of the target detection area by the first camera and acquire the captured images of the target detection area by the second camera.

[0080] It can be understood that, for step C1, the predetermined display method is to display only the capture screen of the specified camera on the display screen, that is, the capture screen of one camera of the first camera and the second camera is visible to the user, and the capture screen of the other camera is invisible to the user. The predetermined display method can be to display the capture screens of each camera in an overlapping manner, with only the top capture screen visible to the user, or to display only the capture screen of one camera and hide the capture screen of the other camera. The embodiment of the present application does not make any specific limitation on this; and, the designated camera can be the first camera or the second camera, and the embodiment of the present application does not make any specific limitation on this.

[0081] Exemplarily, in one implementation, the predetermined display method includes:

[0082] The acquisition pictures of each camera are overlapped and displayed, and the acquisition picture of a specified camera is set on the upper layer of the acquisition picture of another camera.

[0083] It is understandable that the acquisition screens of each camera can be displayed overlappingly. Then, the acquisition screen of the specified camera needs to be set on the upper layer of the acquisition screen of another camera. Therefore, only the acquisition screen of the specified camera can be displayed, and the acquisition screen of another camera will not be displayed. The user can only see the acquisition screen of the specified camera on the display screen.

[0084] In order to better understand the relevant content of the predetermined display method, a brief introduction is given below in conjunction with the accompanying drawings, as shown in Figure 2 (a):

[0085] Figure 2 (a) is a mobile phone screen 01, in which the capture images of the first camera and the second camera overlap, and the capture image of the first camera is located above the capture image of the second camera. Therefore, only the capture image of the first camera 02 can be seen, and the capture image of the second camera cannot be seen, but the capture image of the second camera also exists.

[0086] It can be seen that the embodiment of the present application can make the capture screen of the specified camera visible to the user through a predetermined display method, thereby ensuring that the user can only see the capture screen of the specified camera, and the user will not see the capture screens of two cameras at the same time, thereby improving the user experience.

[0087] It can be understood that the target detection area in the acquisition screen of the specified camera can be highlighted, that is, the overlapping field of view of the first camera and the second camera is displayed more prominently in the acquisition screen. Also, highlighting the target detection area can be to increase the brightness of the target detection area, or to lower the brightness of other areas outside the target detection area. It is also possible to add edge lines of specified shapes to the edges of the target detection area, and highlight the target detection area by using edge lines of specified shapes. The embodiments of the present application do not specifically limit this. It should be noted that the target detection area can also be considered as the detection area of ​​the patient's pressure sore. Since the field of view corresponding to the target detection area belongs to the overlapping video range of the first camera and the second camera, if a pressure sore is displayed in the target detection area, the pressure sore representing the patient can be collected by each camera, which is convenient for the subsequent calculation of the size information of the pressure sore based on the images of each camera to ensure the accuracy of the calculation of the size information.

[0088] Exemplarily, in one implementation, the setting method of the highlighting effect of the target detection area in the captured image of the specified camera includes:

[0089] A mask is set for the area outside the target detection area in the captured image of the specified camera to highlight the target detection area.

[0090] It can be understood that the mask layer can be considered as a layer with lower brightness, and the target detection area is not set with a mask layer, so the target detection area is transparent, thereby achieving the effect of highlighting the target detection area.

[0091] In order to better understand the relevant content about the highlighting effect of the target detection area in the acquisition picture of the specified camera, a brief introduction is given below in conjunction with the accompanying drawings, as shown in Figure 2 (b):

[0092] It can be understood that the display screen 210 in Figure 2 (b) may include a target detection area 211 and other areas 212. The other areas 212 are areas outside the target detection areas introduced above. The target detection area 211 has a highlighting effect, while the other areas 212 are provided with a mask layer with a lower brightness.

[0093] It can be seen that the embodiment of the present application can set a mask for the area outside the target detection area in the capture image of the specified camera to highlight the target detection area, which can facilitate the user to view the target detection area and improve the user experience.

[0094] Exemplarily, in one implementation, prompt information is displayed in the capture screen of the designated camera; wherein the prompt information is used to instruct the user to control the display of the pressure sore in the target detection area.

[0095] It is understandable that prompt information can also be displayed in the acquisition screen of the designated camera, and the prompt information can be used to instruct the user to control the pressure sore to be displayed in the target detection area, so as to facilitate subsequent image acquisition. Only when the pressure sore is displayed in the target detection area can the first camera and the second camera be controlled to acquire the image. In addition, the prompt information can be located in other areas outside the target detection area, or in the target detection area, and the embodiments of the present application do not specifically limit this.

[0096] Of course, other information may also be set in the capture image of the specified camera, such as current time information, current brightness information, etc., and the embodiment of the present application does not specifically limit this.

[0097] In order to better understand the relevant content of the prompt information displayed in the acquisition screen of the specified camera, the following is a brief introduction combined with the accompanying drawings, as shown in Figure 2 (c):

[0098] It is understandable that the display screen 210 may include a target detection area 211 and other areas 212. The highlighted area in FIG2 (c) may be considered to be the target detection area 211 described above. In this figure, the wound is a pressure sore, so the prompt message may be: Please control the pressure sore within the highlighted area.

[0099] It can be seen that prompt information can be displayed in the acquisition screen of the designated camera in the embodiment of the present application, so as to prompt the user to control the display of pressure sores in the target detection area, thereby providing a basis for the measurement of pressure sores.

[0100] It can be seen that the embodiment of the present application can display the acquisition screen of the target detection area on the display screen according to a predetermined display method, and can only display the acquisition screen of the specified camera, which is convenient for users to view the target detection area and improves the user experience.

[0101] S103, acquiring an image including a target acquisition picture to obtain a target image;

[0102] The target acquisition picture is a collection picture of the target detection area by a designated camera, and the designated camera is one of the first camera and the second camera;

[0103] It can be understood that the medical detection equipment can obtain an image containing a captured screen of the target detection area by the designated camera as the target image. The designated camera can be the first camera or the second camera. The designated camera can be selected by the user. When the user does not select the designated camera, a camera can also be selected by default as the designated camera. The embodiment of the present application does not make specific limitations on this; for example: when the user does not select the designated camera, the first camera (the left-hand camera) can be selected by default as the designated camera.

[0104] S104, determining a plurality of target marking points in the target image;

[0105] Wherein, the plurality of target marking points are used to indicate the location points of the pressure sores within the target detection area;

[0106] It can be understood that multiple target marking points can represent the location points of pressure sores in the target detection area, that is, the location points that can characterize the length and width of the pressure sores in the target detection area. Multiple target marking points can be automatically marked by medical detection equipment, or can be marking points obtained by position adjustment by the user. The embodiments of the present application do not make specific limitations on this.

[0107] For the sake of clarity, the process of determining multiple target marking points in the target image will be introduced in subsequent embodiments and will not be described in detail again.

[0108] S105: Calculate the size of the pressure sore based on the multiple target marking points to obtain size information of the pressure sore.

[0109] It can be understood that based on multiple target marking points, the size of the pressure sore can be calculated using a distance calculation formula to obtain the size information of the pressure sore; wherein the size information of the pressure sore may include at least the length and width of the pressure sore. Of course, this is only an exemplary introduction, and the size information may also be the length of the diagonal, and this application does not make any specific limitations on this.

[0110] Exemplarily, the distance calculation formula is: ;

[0111] Among them, the coordinates of a target mark point in any group are ( ), the coordinates of another target marker point in this group are ( ), distance represents the size information of the pressure sore. The above formula can also be considered as a formula for calculating the distance based on two three-dimensional coordinates.

[0112] It should be emphasized that the distance calculation formula is applicable to the scenario where each target mark point belongs to multiple groups. In this scenario, each group contains two target mark points, and the two target mark points in each group can be used to indicate the size information of the pressure sore; specifically, the two target mark points in one group can be used to indicate the length of the pressure sore, and the two target mark points in the other group can be used to indicate the width of the pressure sore. Substituting the target mark points of the above two groups into the above distance calculation formula, the length and width of the pressure sore can be calculated. The above is only an exemplary introduction, and the embodiments of the present application do not make specific limitations on this.

[0113] Of course, using the distance calculation formula to calculate the size information of the pressure sore is only an exemplary introduction, and other methods can also be used to calculate the size information of the pressure sore, and the embodiments of the present application do not specifically limit this. In addition, the coordinates of the target marking point can also be considered as coordinates in a three-dimensional world coordinate system, which will be specifically introduced in other embodiments and will not be described in detail here.

[0114] In order to better understand this part of the content, the following is an introduction with reference to the accompanying drawings, as shown in Figure 2 (d):

[0115] Figure 2 (d) is a target detection area 211 of a captured image. In the figure, there are four target marking points, among which point 1 and point 2 belong to the same group, and point 3 and point 4 belong to the same group. Substituting the three-dimensional coordinates of point 1 and point 2 into the above formula can calculate the width of the pressure sore, and substituting the three-dimensional coordinates of point 3 and point 4 into the above formula can calculate the length of the pressure sore.

[0116] It can be seen that the pressure sore measurement method provided in the embodiment of the present application does not require manual measurement when detecting the size information of the pressure sore, does not need to consume a lot of time, greatly saves human resources, and can improve the efficiency of pressure sore detection; and the embodiment of the present application can simultaneously turn on the first camera and the second camera of the medical detection equipment, and can ensure the synchronization of the images collected by the first camera and the second camera (that is, ensure the imaging synchronization). In theory, the delay between the first camera and the second camera for imaging can reach 0ms, thereby improving the accuracy of pressure sore detection.

[0117] Exemplarily, in one implementation, the method further includes steps D1-D2:

[0118] Step D1, obtaining a target part type of the measurement part to which the pressure sore belongs; wherein the target part type is one of a plurality of predetermined part types, and the plurality of predetermined part types include a first part type representing a left elbow, a second part type representing a right elbow, a third part type representing a spine part, a fourth part type representing a left auricle part, a fifth part type representing a right auricle part, a sixth part type representing an occipital part, a seventh part type representing a face, and an eighth part type representing a shoulder;

[0119] Step D2, in response to the calculated size information of the pressure sore, associating the size information of the pressure sore with the target site type.

[0120] It is understandable that, for step D1, the medical detection equipment can display each of the multiple part types on the display screen in advance, so that the user can select the target part type of the measurement part to which the pressure sore belongs, and thus obtain the target part type of the measurement part to which the pressure sore belongs in response to the user's selection instruction on the display screen. The embodiment of the present application does not make specific limitations on this; illustratively, the options of each of the multiple part types can be displayed on the display screen, and the measurement part to which the pressure sore belongs belongs to the left elbow, so the user can select the first part type as the target part type of the pressure sore. And, the multiple predetermined part types include a first part type representing the left elbow, a second part type representing the right elbow, a third part type representing the spine, a fourth part type representing the left auricle, a fifth part type representing the right auricle, a sixth part type representing the back of the head, a seventh part type representing the face, and an eighth part type representing the shoulder. The embodiment of the present application does not make specific limitations on this.

[0121] It can be understood that, for step D2, after the size information of the pressure sore is calculated, the size information of the pressure sore can be associated with the target part type, and the target part type can also be used as part of the size information; illustratively, after determining the size information of pressure sore 1, the target part type of the measuring part to which pressure sore 1 belongs is determined to be the first part type, and the size information of the pressure sore can be associated with the first part type.

[0122] It can be seen that the embodiment of the present application can obtain the target site type of the measuring site to which the pressure sore belongs, and in response to the calculated size information of the pressure sore, associate the size information of the pressure sore and the target site type, thereby supplementing the size information of the pressure sore. There is no need to manually associate the size information of the pressure sore with the target site type, which reduces the possibility of association errors and can also provide efficiency in detecting pressure sores.

[0123] Exemplarily, in one implementation, the method further includes steps E1-E2:

[0124] Step E1, obtaining a target pressure sore grade to which the pressure sore belongs; wherein the target pressure sore grade is one of a plurality of predetermined pressure sore grades, and the plurality of predetermined pressure sore grades include: stage I pressure sore, stage II pressure sore, stage III pressure sore, stage IV pressure sore, non-stageable pressure sore, and suspected deep tissue injury stage pressure sore;

[0125] Step E2, in response to the calculated size information of the pressure sore, associating the size information of the pressure sore with the target pressure sore grade.

[0126] It can be understood that, for step E1, the medical detection equipment can pre-display multiple pressure sore levels to which the pressure sore belongs on the display screen, so that the user can select the target pressure sore level of the measuring part to which the pressure sore belongs, and thus obtain the target pressure sore level of the measuring part to which the selected pressure sore belongs in response to the user's selection instruction on the display screen. The embodiment of the present application does not make specific limitations on this; illustratively, options for multiple pressure sore levels can be displayed on the display screen, and the pressure sore level to which the pressure sore belongs is stage I pressure sore, so the user can select stage I pressure sore as the target pressure sore level of the pressure sore. In addition, multiple predetermined pressure sore levels include: stage I pressure sores, stage II pressure sores, stage III pressure sores, stage IV pressure sores, unstageable pressure sores, and suspected deep tissue injury stage pressure sores, among which stage I pressure sores are the pressure sores with the lowest degree of injury, stage IV pressure sores are the pressure sores with the highest degree of injury, and unstageable pressure sores may be those with intact skin but subcutaneous nodules or exudate forming on the wound surface. Then, considering the possible existence of deep injury, they can be classified as suspected deep injury; unstageable pressure sores are those with hard scabs formed after skin damage, or necrotic flesh covering the wound surface, and it is unclear to which layer the deep can reach, whether it is muscle, bone, or fat, and the pressure sores cannot be staged. The embodiments of the present application do not specifically limit the multiple predetermined pressure sore levels.

[0127] It can be understood that, for step E2, after the size information of the pressure sore is calculated, the size information of the pressure sore can be associated with the target pressure sore level, and the target pressure sore level can also be used as part of the size information; illustratively, after determining the size information of pressure sore 1, it is determined that the target pressure sore level of pressure sore 1 is a stage I pressure sore, and the size information of the pressure sore can be associated with the stage I pressure sore.

[0128] In order to better understand the target type of measurement site to which the pressure sore belongs and the target pressure sore level to which the pressure sore belongs, the following is an introduction with reference to the accompanying drawings. Figure 3 As shown:

[0129] Marking point 1 and marking point 2 are used to indicate the length of the pressure sore, marking point 3 and marking point 4 are used to indicate the width of the pressure sore, the pressure sore level is stage IV pressure sore, and the location type to which the pressure sore belongs is the first location type of the left elbow, which can also be called the first location type. "Pressure Sore Size" is displayed at the top of the display screen, and a "Start Calculation" button is displayed at the bottom of the display screen, indicating that the size information of the pressure sore can be calculated.

[0130] It can be seen that the embodiment of the present application can obtain the target pressure sore level to which the pressure sore belongs, and in response to the calculated size information of the pressure sore, associate the size information of the pressure sore and the target pressure sore level, thereby supplementing the size information of the pressure sore. There is no need to manually associate the size information of the pressure sore with the target pressure sore level, which reduces the possibility of errors and can also provide efficiency in detecting pressure sores.

[0131] Exemplarily, in one implementation, after displaying the acquisition picture of the target detection area on the display screen, acquiring an image including the target acquisition picture, and before obtaining the target image, the method further includes steps F1-F2:

[0132] Step F1, starting the level meter, and displaying the guidance information about whether the medical detection device is in a horizontal posture, which is recognized by the level meter, on the display screen, so as to guide the operator to adjust the posture of the medical detection device to a horizontal posture;

[0133] Step F2, obtaining a photographing instruction issued by the operator after adjusting the posture of the medical detection device to a horizontal posture, triggering the step of obtaining an image including a target acquisition screen to obtain a target image.

[0134] It can be understood that, for step F1, the level can be used to identify whether the medical detection device is in a horizontal posture. After the acquisition screen of the target detection area is displayed on the display screen, the level of the medical detection device can be started first. The level can identify whether the medical detection device is in a horizontal posture and display guidance information on the display screen to guide the operator to adjust the posture of the medical detection device to a horizontal posture; then, if the level recognizes that the medical detection device is in a horizontal posture, the displayed guidance information can be to guide the operator to send a target photo-taking instruction. On the contrary, if the level recognizes that the medical detection device is not in a horizontal posture, the displayed guidance information can be to guide the operator to adjust the posture of the medical detection device to a horizontal posture. Exemplarily, the level is started, and the level detects that the mobile phone device is not in a horizontal posture. At this time, the guidance information that the mobile phone device recognized by the level is not in a horizontal posture can be displayed to guide the operator to adjust the posture of the mobile phone device to a horizontal posture. In addition, the "operator" introduced here can also be considered as the "user" introduced in other embodiments, and the embodiments of the present application do not specifically limit this.

[0135] Of course, the horizontal posture is not limited to being completely horizontal, that is, the shooting angle of the medical detection equipment relative to the pressure sore is 0°, and the allowable shooting angle is between 5° and -5°. The embodiment of the present application does not make specific limitations on this.

[0136] In order to better understand the content of the guidance information, the following is an introduction with reference to the accompanying drawings, as shown in FIG4 (a) and FIG4 (b):

[0137] FIG4 (a) shows that the mobile phone device is not in a horizontal posture as recognized by the level meter. The display screen 210 may include a target detection area 211 and other areas 212. At this time, the circle with a shadow in the display screen 210 is not aligned with the central circle of the display screen 210. At this time, the user can be guided to adjust the posture of the mobile phone device to a horizontal posture, and a prompt message "Please control the pressure sore within the highlighted area" is displayed at the bottom of the display screen 210. There are also a camera button and a flashlight start button at the bottom of the display screen 210. There are also a display title of "Binocular Distance Measurement" and a "?" button, and a "Gear" button representing the setting at the top of the display screen 210.

[0138] FIG4 (b) shows that the mobile phone device is in a horizontal position as recognized by the level meter. The display screen 210 may include a target detection area 211 and other areas 212. At this time, the circle with a shadow in the display screen 210 is aligned with the center circle of the display screen 210. At this time, the user can be guided to control the binocular camera to shoot, and a prompt message "Please control the pressure sore within the highlighted area" is displayed at the bottom of the display screen 210. There is also a photo button and a flashlight start button at the bottom of the display screen 210. There is also a display title of "Binocular Distance Measurement" and a "?" button, and a "Gear" button representing the setting at the top of the display screen 210.

[0139] It can be understood that, for step F2, after the operator adjusts the posture of the medical detection equipment to a horizontal posture, a photo taking instruction can be obtained, thereby triggering the step of acquiring an image containing the target acquisition screen and obtaining the target image. The target image subsequently acquired can also be considered to be in a horizontal posture.

[0140] It can be seen that the application embodiment can utilize the spirit level provided by the medical detection equipment to display on the display screen the guidance information about whether the medical detection equipment is in a horizontal posture recognized by the spirit level, so as to guide the user to adjust the posture of the medical detection equipment to a horizontal posture, and, when obtaining the photo-taking command issued by the operator after adjusting the posture of the medical detection equipment to a horizontal posture, trigger the step of acquiring an image containing a target acquisition screen and obtaining a target image, so that only when the posture of the medical detection equipment is a horizontal posture can each camera be controlled to capture the image, thereby ensuring the accuracy of the detection of pressure sores; compared with the use of the spirit level in the related art, the embodiment of the present application can display the corresponding guidance information on the display screen based on the posture recognized by the spirit level, thereby ensuring that the medical detection equipment can only be in a horizontal posture when the image can be captured, and the accuracy of the detection of pressure sores is also ensured.

[0141] Exemplarily, in one implementation, the determining of a plurality of target marking points in the target image comprises steps G1-G2:

[0142] Step G1, determining an initial plurality of marking points in the target image; the plurality of marking points at least include a first marking point, a second marking point, a third marking point and a fourth marking point; the first marking point and the second marking point together represent the length of the pressure sore, and the third marking point and the fourth marking point together represent the width of the pressure sore;

[0143] Step G2, in response to obtaining the pressure sore calculation instruction, obtaining multiple current marking points in the target image to obtain multiple target marking points;

[0144] Accordingly, based on the multiple target marking points, the size of the pressure sore is calculated to obtain the size information of the pressure sore, including step H1:

[0145] Step H1, based on the multiple target marking points, calculate the length and width of the pressure sore to obtain the size information of the pressure sore.

[0146] It can be understood that, for step G1, an initial plurality of marking points can be set in the target image. The initial plurality of marking points can be considered as points used to preliminarily locate the pressure sore, and can be automatically generated. When the initial plurality of marking points are automatically generated, they can be generated around the pressure sore, or they can be determined in a specific way. The embodiment of the present application does not make specific restrictions on this; wherein, the multiple marking points can include at least four marking points, namely the first marking point, the second marking point, the third marking point and the fourth marking point. The first marking point and the second marking point jointly represent the length of the pressure sore, and the third marking point and the fourth marking point jointly represent the width of the pressure sore; of course, the above is only an exemplary introduction. In another implementation, 6 marking points can also be included to represent the length, width and diagonal of the pressure sore. The embodiment of the present application does not make specific restrictions on this. In addition, the first marking point and the second marking point can be considered to belong to a group, used to represent the length of the pressure sore, and the third marking point and the fourth marking point can also be considered to belong to a group, used to represent the width of the pressure sore. The embodiment of the present application does not make specific restrictions on this. In addition, the positions of the initial multiple marking points can be obtained by performing image analysis processing on the target image, and the image analysis processing is used to identify pressure sores. The multiple marking points can be the marking position points of the identified pressure sores; and the image analysis processing can be performed using a neural network model, which is not specifically limited in the embodiments of the present application.

[0147] To better understand this part, please refer to Figure 2 (d), as shown in Figure 2 (d):

[0148] The first marking point is the point marked 1, the second marking point is the point marked 2, and the first marking point and the second marking point can jointly represent the length of the pressure sore, the third marking point is the point marked 3, and the fourth marking point is the point marked 4, and the third marking point and the fourth marking point can jointly represent the width of the pressure sore.

[0149] In another embodiment of the present application, the shape of the target detection area is a specified graphic shape, and each initial marking point corresponds to an initial position;

[0150] Methods for determining initial positions corresponding to the initial plurality of marking points in the target image include method J1:

[0151] Mode J1, determining multiple initial positions according to a position determination method that matches the shape category of the specified graphic shape.

[0152] The specified graphic shape may be a rectangle, a circle, etc., and this embodiment of the present application does not specifically limit this.

[0153] It is understandable that when the shape of the target detection area is a specified graphic shape, multiple initial positions can be determined according to a position determination method that matches the shape category of the specified graphic shape; for example, when the target detection area is a circle, multiple positions on the circle that are connected and can represent the diameter can be determined as the initial positions. And, depending on the specified graphic shape, the position determination method that matches the corresponding shape category is also different, and the embodiments of the present application do not specifically limit this.

[0154] Of course, when the shape of the target detection area is not a specified graphic shape, any multiple positions can also be determined in the target detection area as initial positions, and the embodiments of the present application do not make specific limitations on this.

[0155] It can be seen that the embodiment of the present application can determine multiple initial positions according to a position determination method that matches the shape category of the specified graphic shape, and then mark points can be set for the multiple initial positions, so that the initial positions can be quickly located, thereby improving the efficiency of detecting the size information of pressure sores.

[0156] In another implementation, the shape of the graphic is specified to be a rectangle;

[0157] Accordingly, the method J1 determines a plurality of initial positions according to a position determination method matching the shape category of the specified graphic shape, including the method J11:

[0158] Method J11, determining the midpoint position of each side of the border of the target detection area to obtain multiple initial positions.

[0159] It can be understood that method J11 is for the case where the shape of the specified graphic is a rectangle. Then, the position determination method that matches the shape category of the rectangle is: determine the midpoint position of each side of the rectangle represented by the target detection area, thereby determining multiple initial positions, and then a mark point can be set at each initial position. Exemplarily, the shape of the target detection area is a rectangle, the long border of the sub-area is 8cm, and the wide border is 6cm. Then, the midpoint of the long border and the midpoint of the wide border of the target detection area can be determined to obtain multiple initial positions, that is, the position of the long border of 4cm and the position of the wide border of 3cm. Of course, the above is only an exemplary introduction, and the four corners of the rectangle can also be determined as multiple initial positions, and the embodiments of the present application do not specifically limit this.

[0160] It can be seen that when the specified graphic shape is a rectangle, the midpoint position of each side of the border of the target detection area can be determined to obtain multiple initial positions, so that the initial position can be quickly located, thereby improving the efficiency of detecting the size information of pressure sores.

[0161] It can be understood that, for step G2, in response to obtaining the pressure sore calculation instruction, the current multiple marking points in the target image are obtained, which can be used as multiple target marking points. The current multiple marking points in the target image can be marking points after the initial multiple marking points are position adjusted, or can be the initial multiple marking points. The embodiment of the present application does not make specific limitations on this.

[0162] It can be understood that for step H1, the length of the pressure sore can be calculated based on the first marking point and the second marking point, and the width of the pressure sore can be calculated based on the third marking point and the fourth marking point. The calculated length and width of the pressure sore can be used to obtain the size information of the pressure sore.

[0163] It can be seen that the embodiments of the present application can determine multiple target marking points in the target image, so as to obtain the first marking point, the second marking point, the third marking point and the fourth marking point. After responding to the instruction to obtain the pressure sore calculation, the current multiple marking points in the target image data can be obtained to obtain multiple target marking points. Subsequently, the length and width of the pressure sore can be calculated based on the multiple target marking points as the size information of the pressure sore; thus, it is introduced that when there are four marking points, every two marking points can be grouped as a group to characterize the length and width of the pressure sore, which is convenient for calculating the size information of the pressure sore and can also ensure the accuracy of the detection of the pressure sore.

[0164] Exemplarily, in one implementation, the target image is displayed on the display screen;

[0165] After determining the initial plurality of marking points in the target image, the method further comprises step K1:

[0166] Step K1, in response to an operator's operation of adjusting the position of at least one marking point in the target image, adjusting the position of at least one marking point;

[0167] Before acquiring the current multiple marking points in the target image to obtain multiple target marking points, the method further includes steps L1-L2:

[0168] Step L1, for each mark point after position adjustment, detecting whether the difference between the mark point after position adjustment and the position before adjustment exceeds a predetermined distance, and obtaining a judgment result of the mark point after position adjustment;

[0169] Step L2, if the judgment results corresponding to the mark points after the positions are adjusted all indicate that they do not exceed the predetermined distance, the step of acquiring the current multiple mark points in the target image to obtain multiple target mark points is triggered; otherwise, a notification message for indicating that the mark points are abnormal is output.

[0170] It is understood that, for step K1, the operator can adjust the position of at least one mark point in the target image by touching the display screen, and the medical detection device can adjust the position of at least one mark point in response to the position adjustment operation. Exemplarily, after the operator performs a position adjustment operation on any mark point, in response to the user's position adjustment operation on the mark point, the mark point is displayed according to the target display mode, and the mark point is adjusted according to the adjustment track indicated by the position adjustment operation; wherein the target display mode includes enlarging and displaying the mark point, and the mark point and another mark point in the group to which the mark point belongs have a connecting line. It is understood that the first mark point and the second mark point can belong to a group, and the third mark point and the fourth mark point can belong to a group; then, in the target display mode, the mark point on which the operator performs the position adjustment operation can be enlarged and displayed, and a solid line can be used to connect the mark point and another mark point in the group to which the mark point belongs; based on the target display mode, the user can clearly see the position and connecting line of the mark point. Furthermore, the position of the marking point can be adjusted according to the adjustment track indicated by the position adjustment operation so that the current position of the marking point is the position expected by the operator, that is, the position that can characterize the size information of the pressure sore in the target image.

[0171] It is understandable that for step L1, considering the possibility of false touch, for each mark point after position adjustment, it is possible to detect whether the difference between the mark point after position adjustment and the position before adjustment exceeds the predetermined distance, so as to obtain the judgment result of the mark point after position adjustment; then, the judgment result can represent exceeding the predetermined distance, or not exceeding the predetermined distance, and the predetermined distance can be an empirical value, for example: it can be the length of the target detection area, or the width of the target detection area, and the embodiment of the present application does not make specific limitations on this. For example, the predetermined distance is 5cm, and the difference between the mark point 1 after position adjustment and the position before adjustment is 4cm, then it can be judged that the result can be characterized as exceeding the predetermined distance.

[0172] It can be understood that, for step L2, when the judgment results corresponding to the mark points after adjustment at each position all indicate that they do not exceed the predetermined distance, it can be considered that the probability of a false touch is small. At this time, the step of acquiring the current multiple mark points in the target image and obtaining multiple target mark points can be triggered; conversely, when the judgment result corresponding to the mark point after adjustment at any position exceeds the predetermined distance, a notification message for indicating that the mark point is abnormal can be output, prompting the operator that a false touch may have occurred. For example, the notification message may be "Please check whether the mark point has been falsely touched". The embodiment of the present application does not specifically limit the notification message.

[0173] It can be seen that the embodiment of the present application can analyze whether the difference between each mark point after the position adjustment and the position before the adjustment exceeds the predetermined distance after the position adjustment of the mark point, and only when the judgment results corresponding to each mark point after the position adjustment indicate that the distance is less than the predetermined distance, trigger the step of acquiring the current multiple mark points in the target image to obtain multiple target mark points, thereby greatly reducing the probability of false touch and improving the accuracy of pressure sore detection.

[0174] Exemplarily, in one implementation, the first camera and the second camera are located on the same side of the medical detection device and arranged horizontally; the medical detection device further includes: a QR code scanning unit located at the top;

[0175] The method further comprises steps M1-M2:

[0176] Step M1, scanning the patient's QR code by a QR code scanning unit, and obtaining the patient's information based on the QR code;

[0177] It can be understood that the QR code scanning unit can be integrated into a separate camera for scanning codes, which can be set on the top of the medical detection equipment. There is a corresponding built-in service inside the medical detection equipment. After pressing the camera button, the QR code scanning unit can read the QR code and obtain patient information through algorithm analysis; wherein, the patient information includes but is not limited to the patient's age, gender, admission time, target site type of the measurement site to which the pressure sore belongs, target pressure sore level to which the pressure sore belongs, and measurement time, etc.; patient information can also be stored in the form of a document in a designated server, and the implementation of this application does not specifically limit the patient information. In addition, the first camera and the second camera can be located on the same side of the medical detection equipment and arranged horizontally. The embodiment of this application does not limit the specific positions of the first camera, the second camera and the QR code scanning unit. Of course, the QR code scanning unit introduced above is only an exemplary introduction and does not limit the embodiment of this application.

[0178] Step M2, in response to calculating the size information of the pressure sore, associating the patient information with the size information of the pressure sore.

[0179] It can be understood that in response to calculating the size information of the pressure sore, the patient information obtained through the QR code scanning unit can be associated with the size information of the pressure sore, and the size information of the pressure sore can be considered as part of the patient information. The patient information can be subsequently saved to a designated server; the next time the patient's QR code is scanned by the QR code scanning unit, the acquired patient information may include the size information of the pressure sore.

[0180] It can be seen that the medical detection equipment of the embodiment of the present application may also include a QR code scanning unit. After scanning the patient's QR code, the patient information can be obtained based on the QR code, and the patient information can be associated with the size information of the pressure sore. There is no need to manually associate the patient information with the size information of the pressure sore, which reduces the possibility of association errors and also improves the efficiency of detecting pressure sores.

[0181] Exemplarily, in one implementation, the size information may also be associated with the target image; then, the size information may be added to the target image as watermark information, and / or, the size information may be added to the image name of the target image. It is understandable that by adding the size information as watermark information to the target image, subsequent users can directly see the size information of the wound as watermark information in the target image; the size information may also be directly added to the image name of the target image, for example: the name of the target image is the wound image of patient a (the length of the wound is 30 mm, and the width is 40 mm); of course, the size information may also be added to the target image as watermark information, and the size information may also be added to the image name of the target image, thereby realizing the association of the size information with the target image, and the embodiments of the present application do not specifically limit this.

[0182] In order to better understand the relevant content of associating the size information with the target image, the following is introduced in conjunction with the accompanying drawings. Figure 6 As shown:

[0183] The watermark information in the figure indicates that the distance between target mark point 1 and target mark point 2 is 24.1mm, that is, the length (1-2)-24.1mm, the distance between target mark point 3 and target mark point 4 is 49.95mm, that is, the length (3-4)-49.95mm, the location: elbow (left), the pressure sore level: stage 4 pressure sore. In addition, a "Take another photo" button is set under the interface for continuing to take photos, and there is also a display title of "Pressure Sore Size" and a "?" button on the top of the interface.

[0184] It can be seen that the embodiments of the present application can add the size information as watermark information to the target image, and / or add the size information to the image name of the target image, thereby realizing the association between the size information and the target image. Medical staff can subsequently retrieve the target image without manually associating the wound size information with the target image, thereby reducing the possibility of errors and improving the efficiency of wound detection.

[0185] Exemplarily, in one implementation, the calculating the size of the pressure sore based on the multiple target marking points to obtain the size information of the pressure sore includes steps N1-N2:

[0186] Step N1, based on the first type coordinates and the second type coordinates of the multiple target marking points, convert the multiple target marking points into a predetermined spatial coordinate system to obtain the spatial coordinates of the multiple target marking points, wherein the first type coordinates of any target marking point are image coordinates with respect to the first camera, and the second type coordinates of any target marking point are image coordinates with respect to the second camera;

[0187] It can be understood that based on the image coordinates of the multiple target marking points in the first camera and the image coordinates of the second camera, the multiple target marking points can be converted into a predetermined spatial coordinate system, so that the spatial coordinates of the multiple target marking points can be obtained, wherein the predetermined spatial coordinate system can be a world three-dimensional coordinate system or other spatial coordinate systems, and the spatial coordinates can be coordinates under the world three-dimensional coordinate system, and the embodiments of the present application do not make specific limitations on this.

[0188] Also, in the process of coordinate conversion in step N1, the first type of coordinates and the second type of coordinates can be referenced, that is, the captured images of the first camera and the second camera are referenced, rather than only the images captured by the specified camera. The reference dimensions are more and the accuracy of pressure sore detection is improved. In addition, the image coordinates represented by the first type of coordinates and the second type of coordinates can be determined based on pixels. For example, the pixels of the target image are 2448×3264, the first type of coordinates of the target marker point 1 are (1200, 1000), and the first type of coordinates of the target marker point 2 are (1600, 1000).

[0189] In addition, any coordinate conversion method in the related art can be applied to the embodiments of the present application. The following is an exemplary introduction to one of the coordinate conversion methods:

[0190] In another implementation, based on the first type coordinates and the second type coordinates of the multiple target marking points, the multiple target marking points are converted into a predetermined spatial coordinate system to obtain the spatial coordinates of the multiple target marking points, including steps N11-N12:

[0191] Step N11, determining the marking points corresponding to each target marking point in the image captured by another camera other than the designated camera, to obtain each designated marking point;

[0192] It can be understood that the first camera and the second camera can simultaneously capture images about the pressure sore, and there is a complete pressure sore within the overlapping field of view of the two cameras, so there is a complete pressure sore in the target image captured by the designated camera and the image captured by another camera other than the designated camera; then, a pixel conversion relationship between the two cameras can be established in advance, so that after knowing the coordinates of each target marking point in the target image captured by the designated camera, the marking points corresponding to the target marking points in the image captured by the other camera can be determined based on the above pixel conversion relationship, that is, each designated marking point. Of course, it is also possible to obtain the image coordinates of each target marking point in the designated camera, and determine the marking points corresponding to each target marking point in the image captured by another camera other than the designated camera through an image matching algorithm. Specifically, any image matching algorithm can be used as the image matching algorithm in this application, and no specific limitation is made here; and this application does not limit the specific implementation method of determining the marking points corresponding to each target marking point. It can be understood that the designated camera can be the first camera or the second camera. For example, when the designated camera is the first camera, the process of determining each designated marking point can be considered as determining the corresponding point of each target marking point in the image taken by the second camera.

[0193] Step N12, based on the current image coordinates of each target marking point, the current image coordinates of each designated marking point and the reference file, convert the current image coordinates of each target marking point into the spatial coordinates of each target marking point; wherein the reference file is a file used to convert the image coordinates into coordinates in the world three-dimensional coordinate system.

[0194] It can be understood that the current image coordinates of each target marking point can be either the first type of coordinates or the second type of coordinates. Then, the current image coordinates of each designated marking point are another type of coordinates, and the embodiments of the present application do not make specific limitations on this. For example, when the current image coordinates of each target marking point are the first type of coordinates, the current image coordinates of each designated marking point are the second type of coordinates.

[0195] It can be understood that the reference file is a pre-established auxiliary file for converting image coordinates into coordinates in the world three-dimensional coordinate system. The image coordinates can be converted using the reference file; then, the current image coordinates of each target marker point can be determined first. When converting the current image coordinates of each target marker point, the current image coordinates of each designated marker point can be taken into account, rather than just the image taken by the designated camera. In this way, the spatial coordinates in the world three-dimensional coordinate system converted from the images taken by the two cameras will be more accurate. In addition, the reference file can also be called a binocular camera calibration file, which is not specifically limited in the embodiments of the present application. Also, any coordinate conversion method can be applied to the embodiments of the present application, which is not specifically limited in the present application.

[0196] For example, in one implementation, the principle of converting the current image coordinates of each target marker point into the spatial coordinates in the world three-dimensional coordinate system can be found in Figure 5 As shown:

[0197] Figure 5 is a top-down view taken for the physical point O. In this embodiment, the left camera is the first camera, the right camera is the second camera, the left camera is the designated camera introduced in the above embodiment, the left camera can also be called CL, i.e., Camera Left, and the right camera can also be called CR, i.e., Camera Right, the distance between the left camera and the right camera is b, which can also be called the baseline distance. The baseline distance can be obtained through the above reference file. The point corresponding to the physical point O in the image taken by the left camera is p, and the point corresponding to the physical point O in the image taken by the right camera is p'. ZL is the Z axis corresponding to the left camera, and ZR is the Z axis corresponding to the right camera. The vertical distance between the left camera and the right camera and the X axis is the focal length f. The vertical distance between the left camera and the right camera from the physical point O in the direction of the Z axis is Z, the vertical distance between the left camera and the physical point O in the direction of the X axis is X, the vertical distance between the left camera and p in the direction of the X axis is xL, and the vertical distance between the right camera and p' in the direction of the X axis is xR. It should be emphasized that the parallax between the left camera and the right camera can be considered as the difference between xL and xR; and p and p' can be called the same point.

[0198] And, based on Figure 5The top-down perspective can be used to calculate the distance (X) of the physical point O about the X-axis and the distance (Z) about the Z-axis in the world 3D coordinate system; specifically, for the left camera, based on the principle of similar triangles, the formula Z / f=X / xL can be obtained, and through transformation, Z=X×f / xL can be obtained; for the right camera, based on the principle of similar triangles, the formula Z / f=(Xb) / xR can be obtained, and through transformation, Z=(Xb)×f / xR can be obtained.

[0199] In addition, based on the camera coordinate system of the right camera, the three-dimensional coordinates of p' in the camera coordinate system of the right camera can be obtained. Through the y value of the three-dimensional coordinates, the distance (Y) of the physical point O about the Y axis in the world three-dimensional coordinate system can be obtained. Specifically, through the three-dimensional coordinates of p' in the camera coordinate system of the right camera, the Pythagorean theorem can be used to calculate the distance of p' from the origin of the camera coordinate system of the right camera, and p' and the physical point O are points on the same line. Therefore, through the principle of similar triangles, the distance of the physical point O from the origin of the camera coordinate system of the right camera can also be calculated, so that the distance (Y) of the physical point O about the Y axis in the world three-dimensional coordinate system can be calculated, and then the coordinates of the physical point O in the world three-dimensional coordinate system can be determined.

[0200] It should be emphasized that any coordinate transformation method can be applied to the transformation of points in the image coordinate system to the camera coordinate system in this application, and this application does not make any specific limitations on this; and any method of calculating physical points in the world three-dimensional coordinate system can be applied to this application, and this application does not make any specific limitations on this.

[0201] Step N2, calculating the size of the pressure sore according to the spatial coordinates of the multiple target marking points to obtain the size information of the pressure sore.

[0202] It can be understood that the spatial coordinates can be coordinates in the world three-dimensional coordinate system, so it can be a three-dimensional coordinate. Then, the size of the pressure sore can be calculated based on the spatial coordinates of multiple target marking points to obtain the size information of the pressure sore. The calculation method can be to use the distance calculation formula introduced in step S105 to calculate the size information of the pressure sore, or it can be to use any method in the relevant technology to calculate the size information of the pressure sore. The embodiment of the present application does not make specific limitations on this.

[0203] It can be seen that in the process of calculating the size of the pressure sore, the multiple target marking points can be converted into a predetermined spatial coordinate system based on the first-class coordinates and the second-class coordinates of the multiple target marking points, so as to obtain the spatial coordinates of the multiple target marking points. According to the spatial coordinates of the multiple target marking points, the size of the pressure sore is calculated to obtain the size information of the pressure sore. In this process, the image coordinates of the first camera and the image coordinates of the second-class camera are taken into account to ensure the accuracy of the detection of pressure sores.
