[0031] The application will be described in further detail below with reference to the drawings and embodiments. It can be understood that the specific embodiments described herein are only used to explain the related application, and not to limit the application. In addition, it should be noted that only parts related to the application are shown in the drawings for ease of description.

[0032] It should be noted that the embodiments and features in the embodiments of the present application can be combined with each other without conflict. The application will be described in further detail below with reference to the drawings and embodiments. In addition, the term "and / or" herein is only used to describe the association relationship of the associated objects, which means that there can be three relationships, for example, A and / or B, which means that there are three cases of A alone, A and B together, and B alone. The terms "first" and "second" in the description and claims of the embodiments of the present application are used to distinguish different objects, and not to describe a specific order of the objects.

[0033] The varicose vein marking method provided by the embodiments of the present application can be applied to the varicose vein marking device as shown in Figure 1 The varicose vein marking device includes a camera device 10, a control device 20 and a marking device 30. The camera device 10 is used to obtain an image of a varicose vein part to be marked, for example, a leg image of a marking object in the figure. The control device 20 is used to confirm the specific position of the varicose vein according to the image, and control the marking device 30 to apply a developing agent according to the confirmed varicose vein position, so as to realize automatic detection and marking of the varicose vein part.

[0034] In one embodiment, a varicose vein marking method is provided, which includes the steps as shown in Figure 2

[0035] Step 101, obtaining an image of a varicose vein part to be marked, and performing color detection and flatness detection on the varicose vein part in the image to obtain a detection result.

[0036] In the embodiments of the present application, the varicose vein part of the marking object is photographed by the camera device 10 to obtain an image of the varicose vein part, and then the image is transmitted to the control device 20 in a wired or wireless manner.

[0037] It can be understood that the varicose vein part often presents a color darker than the skin color, for example, blue, red, purple, etc.; or presents a worm-like protrusion, or both. Therefore, the varicose vein part to be marked can be color detected, or flatness detected, or both color detected and flatness detected according to the image of the varicose vein part, to obtain a varicose vein part detection result.

[0038] ​The detection result can include a morphological parameter of the varicose vein part to be marked and a severity of different positions of the varicose vein part to be marked. The morphological parameter is used to represent a line shape of the varicose vein and a vein width at different positions of the varicose vein. The severity of different positions of the varicose vein part to be marked can be represented by a grade, for example, severe, relatively severe, and mild, or represented by a number, for example, 1, 2, 3, 4, and 5. The larger the number is, the higher the severity is.

[0039] In the embodiment of the application, the control device 20 can perform color detection and / or flatness detection on the varicose vein part image by using the pre-trained varicose vein part detection model to obtain a color detection result and / or a flatness detection result. The varicose vein part detection result can be obtained by analyzing the color detection result and / or the flatness detection result. Specifically, since the color of the varicose vein part is different from the color of the non-varicose vein part, and the flatness of the varicose vein part is different from the flatness of the non-varicose vein part, the specific position of the varicose vein in the image, the line shape of the varicose vein, the width at different positions of the varicose vein, the concave-convex condition at different positions of the varicose vein, the concave-convex degree, and the like can be determined by the color detection result and / or the flatness detection result. Then, the morphological parameter of the varicose vein part and the severity at different positions of the varicose vein part can be obtained by analysis. The color depth and the flatness of different positions of the varicose vein part can also represent the severity of different positions of the varicose vein part. It can be understood that the color is positively correlated with the severity, that is, the darker the color is, the more severe the varicose vein is. The flatness is negatively correlated with the severity, that is, the more flat the surface of the varicose vein part is, the less severe the varicose vein is.

[0040] The training process of the varicose vein part detection model can be as follows. First, a plurality of varicose vein part images can be obtained, and the varicose vein parts in the plurality of varicose vein part images can be color labeled and / or flatness labeled to obtain sample images. Then, the sample images can be divided into a training set and a test set, and an initial model can be trained until the model accuracy reaches a preset accuracy. Then, the varicose vein part detection model is obtained.

[0041] In step 102, a developing agent coating path is determined according to the morphology of the varicose vein part, and a developing agent coating dose at a corresponding position is determined according to the severity of the varicose vein part at different positions.

[0042] The coating path covers the varicose vein part to be marked.

[0043] In the embodiments of the present application, the developing agent coating starting point, the developing agent coating ending point, and the coating path between the developing agent coating starting point and the developing agent coating ending point of the varicose vein part to be marked can be determined according to the morphological parameters of the varicose vein part to be marked. The planned coating path should cover each varicose vein of the varicose vein part to be marked, so as to ensure the effectiveness and comprehensiveness of the development of the varicose vein part to be marked, that is, to ensure the accuracy of the marking of the varicose vein part.

[0044] In a possible implementation manner, for a varicose vein part to be marked with complex morphology, a plurality of opposite coating starting points and coating ending points can be planned, and correspondingly, the coating scheme can have a plurality of coating paths.

[0045] The varicose vein severity is different at different positions of the varicose vein part to be marked. For the more serious varicose vein position, the developing agent coating dose can cover the varicose vein part, for example, the width of the developing agent after coating at the dose can be greater than the width of the varicose vein at the corresponding position; for the varicose vein position with lighter severity, since its color, flatness and the like are not obvious relative to other varicose vein positions, relatively more developing agent can be coated to ensure effective development of the varicose vein with lighter severity.

[0046] Therefore, the developing agent coating dose is different at different positions of the varicose vein part to be marked, that is, the developing agent dose coated on different sections of the coating path is different. Specifically, the severity at different positions of the varicose vein part to be marked can be negatively correlated with the developing agent coating dose.

[0047] In step 103, the developing agent is coated on the varicose vein part to be marked according to the coating path and the coating dose at different positions of the varicose vein, and the varicose vein part is marked.

[0048] In the embodiments of the present application, after the coating path and the coating dose are determined, the controller 20 can control the marking device 30 to move along each coating path from the starting point to the ending point of the coating path, and in the moving process, the developing agent is discharged to coat the varicose vein part of the marking object. While controlling the marking device 30 to move along the coating path, the controller 20 controls the developing agent discharge dose of the marking device 30 according to the coating dose at different positions of the varicose vein, so as to ensure the accuracy of the developing agent coating.

[0049] In a possible implementation, the application can mark varicosities in the case of a preoperative flat lying of the marking object. In this case, the color and unevenness of the varicose part of the marking object are not obvious, so before obtaining the image of the varicose part to be marked, the varicose part of the marking object can be coated in a large range and all aspects to make the varicose part of the varicose object to be marked initially develop, and at the same time, the varicose part area with unobvious varicose can be avoided to be missed, and the effectiveness and comprehensiveness of the development are ensured. That is, for the marking object in the preoperative flat lying condition, when coating for the first time, the varicose part is coated in a large range, and then the image of the varicose part to be marked is obtained. Based on the image, color detection and flatness detection are performed, and then based on the detection result, the coating path and coating dose are determined, and then secondary coating is performed. When the secondary coating is performed, the varicose part to be marked is coated with a developing agent according to the coating path and the coating dose at different positions of the varicose part, so as to increase the definition of the varicose part initially developed, and ensure the marking accuracy of the varicose part. The application can mark varicose in the case of preoperative flat lying of the marking object, and can also avoid the problem that the marking object moves in a large range from the varicose part after marking to the preoperative time, so that the image of the varicose part to be marked is greatly different from the preoperative image, thereby affecting the intraoperative effect.

[0050] In a possible implementation, to ensure the marking effect of the varicose part, the varicose part can be coated with a developing agent for multiple times to ensure the clear development of the varicose part. For multiple coating, after each coating, the development effect of the coated varicose part is detected until the development effect of the coated varicose part reaches a preset effect, the developing agent is stopped from being coated on the varicose part to be marked, and the marking of the varicose part is completed.

[0051] Here, the development effect can be the definition of the varicose part, and the preset effect can be a preset definition threshold.

[0052] In the embodiment of the application, in the case of multiple developing agent coatings on the varicose part, the image of the coated varicose part can be captured after each coating, and the definition of the varicose part after the developing agent coating can be determined by image processing on the image of the coated varicose part until the definition of the varicose part after the developing agent coating reaches a preset definition threshold, which indicates that the development effect of the varicose part is good and clear enough to intuitively show the varicose symptoms of the marking object, and is convenient for subsequent surgical treatment. Therefore, the developing agent can be stopped from being coated on the varicose part to be marked, and the marking of the varicose part is completed.

[0053] In a possible implementation manner, the number of coating times can also be preset according to the developing effect of the developer itself or experience, so that the varicose vein part after being coated according to the preset number of coating times is clear enough. In the case of the preset number of coating times, the number of coating times is recorded after each coating until the number of coating times reaches the preset number, the varicose vein part to be marked is stopped from being coated with the developer, and the marking of the varicose vein part is completed.

[0054] In the embodiment of the present application, when the control device 20 controls the marking device 30 to coat the varicose vein part to be marked, the coating parameter N can be set in advance, and N is initialized as 0. After each coating is completed, N is modified as N+1 to record the number of coating times of the developer, until N reaches the preset number, which indicates that the developing effect of the varicose vein part after being coated reaches the preset effect, and the varicose vein part of the marking object is clear enough. Therefore, the varicose vein part to be marked can be stopped from being coated with the developer, and the marking of the varicose vein part is completed.

[0055] The varicose vein marking method provided in the embodiment of the present application first acquires the varicose vein part image, performs color detection and / or flatness detection on the varicose vein part to be marked according to the varicose vein part image, and obtains a detection result. Then, the coating path of the developer and the coating dose of the varicose vein part at different positions are determined according to the initial varicose vein part detection result, and the varicose vein part to be marked is coated with the developer according to the coating path and the coating dose, and the marking of the varicose vein part to be marked is completed. The method provided in the embodiment of the present application uses the developer to develop the varicose vein part by coating, which can realize more convenient and fast development of the varicose vein part compared with the injection method of the developer, and can avoid damage to the human body caused by injection of the developer. In addition, the detection result of the varicose vein part to be marked is obtained by image detection, and the coating path and the coating dose of the developer are controlled according to the detection result, so that the coating scheme of the developer is more consistent with the morphology and state (severity) of the varicose vein part, and the effectiveness of the developer coating is ensured, that is, the accuracy of the marking of the varicose vein part is ensured.

[0056] The embodiments described in the foregoing provide a coating scheme for the varicose vein part multiple times. In another embodiment of the present application, the coating path and the coating dose can be updated according to the development of the varicose vein part after each coating, to ensure the effectiveness of the developer coating and ensure the accuracy of the marking. For example, the "marking of the varicose vein part by coating the varicose vein part to be marked with the developer according to the coating path and the coating dose of the varicose vein part at different positions" includes the steps as shown in Figure 3 .

[0057] In step 201, after each coating, an image of the coated varicose part is collected, color detection and flatness detection are performed on the image of the coated varicose part, and a detection result of the coated varicose part is obtained.

[0058] In step 202, the coating path of the developing agent and the coating dose at different positions of the varicose part are re-determined according to the detection result of the coated varicose part.

[0059] In step 203, the next developing agent coating of the varicose part is performed according to the re-determined coating path and the coating dose at different positions of the varicose part.

[0060] In the embodiments of the present application, considering that the developing situation of the varicose part may change after each coating in the case of multiple coatings of the developing agent, in order to ensure the effectiveness of the next coating, the image of the coated varicose part can be collected after each coating, and color detection and flatness detection can be performed on the image of the coated varicose part, and a detection result of the coated varicose part is obtained, that is, the morphology and severity at different positions of the coated varicose part are obtained.

[0061] Then, the coating path of the developing agent and the coating dose at different positions of the varicose part are re-determined according to the morphology and severity at different positions of the coated varicose part, and the coating path and the coating dose are updated, so that the updated coating path and the coating dose are more in line with the current developed varicose situation. The next developing agent coating of the varicose part is performed according to the re-determined coating path and the coating dose at different positions of the varicose part, so as to ensure the accuracy of each coating in the case of multiple coatings, and further ensure the accuracy of the varicose marking.

[0062] The method provided in the embodiments of the present application can re-detect the developing situation of the varicose part after each coating in the case of multiple coatings of the developing agent on the varicose part, re-determine the coating path of the developing agent and the coating dose at different positions of the varicose part, and perform the next developing agent coating according to the re-determined coating path and the coating dose, so as to ensure the accuracy of each coating in the case of multiple coatings and ensure the accuracy of the varicose marking.

[0063] The foregoing embodiments introduce a scheme for detecting developing effect in the case of multiple coatings of the developing agent. In another embodiment of the present application, the developing effect can be determined by the difference between the developing situations of two adjacent coatings. For example, the "detecting the developing effect of the coated varicose part" mentioned in the foregoing can include the steps as shown in Figure 4

[0064] ​In step 301, an image of the varicose part after coating is acquired, and color detection and flatness detection are performed on the varicose part after coating according to the marked varicose part image, to obtain a detection result of the varicose part after coating.

[0065] In step 302, a difference between the detection result of the varicose part after coating and the detection result of the varicose part before coating is determined.

[0066] In step 303, the developing effect of the varicose part after coating is determined according to the difference.

[0067] In the embodiment, in the case of multiple coatings of the developing agent, for each coating, after coating, an image of the varicose part after coating is acquired, and color detection and flatness detection are performed on the varicose part after coating according to the marked varicose part image, to obtain a detection result of the varicose part after coating, that is, a morphology of the varicose part after coating and a severity of the varicose part at different positions. Then, a morphology difference between the varicose part before coating and the varicose part after coating, and a severity difference between the varicose part before coating and the varicose part after coating can be calculated respectively, and the difference between the varicose part before coating and the varicose part after coating is determined according to the two differences by mean calculation or weighted summation. Finally, the developing effect of the varicose part after coating is determined according to the difference.

[0068] It can be understood that the smaller the difference between the varicose part before coating and the varicose part after coating, the more stable the developing effect of the varicose part after coating of the developing agent, that is, the developing effect of the varicose part tends to be the preset effect. Therefore, whether the developing effect of the varicose part reaches the preset effect can be determined by a preset difference threshold. Specifically, if the difference is less than or equal to the preset difference threshold, it is determined that the developing effect of the marked varicose part reaches the preset effect.

[0069] In the embodiment, the difference threshold can be set in advance, and when the difference between the varicose part before coating and the varicose part after coating is less than the preset difference threshold, it is determined that the developing effect of the varicose part reaches the preset effect, and the coating of the developing agent on the varicose part can be stopped.

[0070] In a possible implementation, the image of the varicose part after coating is acquired, and a difference value image of the image of the varicose part after coating and the image of the varicose part before coating can also be calculated, the difference between the varicose part before coating and the varicose part after coating is determined through the difference value image, and then the developing effect of the varicose part is determined according to the difference.

[0071] The method provided in the embodiments of the present application can determine the developing effect of the varicose vein part after coating by the difference between the varicose vein part before coating and the varicose vein part after coating. That is, the embodiments of the present application can determine the developing effect of the varicose vein part in real time and accurately by the difference between before and after coating, so as to stop the developing agent coating in time when the developing effect reaches the preset effect, and improve the labeling efficiency of the developing agent.

[0072] The foregoing embodiments introduce the scheme of detecting the varicose vein part. In another embodiment of the present application, the varicose vein part to be labeled can be labeled based on the detection result of the varicose vein part to be labeled after the developing process. For example, the foregoing “color detection and flatness detection of the varicose vein part in the image to obtain the detection result” includes the steps shown in the following table: Figure 5

[0073] Step 401: Color detection of the varicose vein part in the image to obtain the hue and brightness of the varicose vein part at different positions.

[0074] Step 402: Flatness detection of the varicose vein part in the image to obtain the flatness of the varicose vein part at different positions.

[0075] Step 403: Determination of the morphology of the varicose vein part according to the hue and flatness of the varicose vein part at different positions.

[0076] Step 404: Determination of the severity of the varicose vein part at different positions according to the brightness and flatness of the varicose vein part at different positions.

[0077] In the embodiments of the present application, after obtaining the image of the varicose vein part to be labeled, color detection is performed on the varicose vein part in the image to obtain the hue and brightness of the varicose vein part at different positions; and flatness detection is performed on the varicose vein part in the image by laser or other methods to obtain the flatness of the varicose vein part at different positions.

[0078] Then, according to the hue of the varicose vein part at different positions, the color difference between the varicose vein part and the non-varicose vein part can be determined based on the color difference between the varicose vein part and the non-varicose vein part; or according to the flatness of the varicose vein part at different positions, the flatness difference between the convex varicose vein part and the flat non-varicose vein part can be determined based on the flatness difference between the convex varicose vein part and the flat non-varicose vein part. Finally, the two limits (for example, one of them or the median of the two limits) can be fused to determine the morphology of the varicose vein part.

[0079] ​According to the brightness of different positions of the varicose part, the severity of different positions of the varicose part can also be determined based on the brightness difference between different positions of the varicose part with different severity; and according to the flatness of different positions of the varicose part, the protrusion degree of different positions of the varicose part can be determined, and then the severity of different positions of the varicose part can be determined.

[0080] The method provided in the embodiments of the present application can obtain the hue, brightness and flatness parameters of different positions of the varicose part by color detection and flatness detection on the varicose part in the image. Then, the boundary between the varicose part and the non-varicose part can be determined according to the above parameters, the morphology of the varicose part can be determined, and the severity of different positions of the varicose part can be determined. The embodiments of the present application can detect the varicose part through multiple parameters, thereby improving the detection accuracy of the varicose part.

[0081] In one embodiment, to further improve the accuracy of the varicose part marking, the detection result of the varicose part to be marked after the development processing can also be manually reviewed. The embodiment includes the steps as shown in Figure 6 .

[0082] Step 501, a review request is sent to a reviewer, and the review request includes a varicose part image after marking.

[0083] Step 502, the review result returned by the reviewer is received, and the varicose part image after marking is corrected according to the review result.

[0084] The review result includes the marking result of the varicose part by the reviewer.

[0085] In the embodiments of the present application, the varicose part image after marking is photographed and sent to the terminal of the reviewer as a review request, prompting the reviewer to manually check the marking result of the varicose part, and receiving the review result of correct marking or incorrect marking returned by the reviewer. When the review result is incorrect marking, the marking result of the varicose part by the reviewer can be included.
