[0038] In addition, numerous specific details are provided in the following detailed description to better illustrate the present disclosure. Those skilled in the art will appreciate that the present disclosure can be practiced without certain specific details. In some instances, methods, means, components, and circuits well known to those skilled in the art are not described in detail in order to highlight the main points of the present disclosure.

[0039] Figure 2 A flowchart of a three-dimensional data display method according to an embodiment of the present disclosure is shown. The three-dimensional data display method can be executed by a terminal device, which can be a user equipment (UE), a mobile device, a user terminal, a terminal, a cellular phone, a cordless phone, a personal digital assistant (PDA), a handheld device, a computing device, a vehicle-mounted device, a wearable device, or other electronic device. The method can be implemented by a processor of the electronic device calling computer-readable instructions stored in a memory. Figure 2 As shown, the three-dimensional data display method includes:

[0040] In step S11 , three-dimensional scanning data of a human body part is acquired.

[0041] In one possible implementation, the three-dimensional scanning data may be three-dimensional data obtained by scanning a human body part using a CT device. The CT device may transmit the scanned three-dimensional scanning data directly to the above-mentioned electronic device, or may also transmit it to a back-end server, which in turn sends the data to an electronic device that needs to view a slice image of a human body part, etc. This is not limited to the embodiments of the present disclosure.

[0042] The three-dimensional scanning data includes slice data of a human body part in three dimensions and slice position information corresponding to the three-dimensional slice data of the human body part. The human body part may include, for example, the abdomen, chest, head, etc., which is not limited in the embodiments of the present disclosure; the slice data can be understood as the three-dimensional data required to render a slice image of the human body part. The slice data can be three-dimensional data in a preset data format (such as vis3D format) to facilitate electronic devices to render the slice image. The slice position information includes the slice positions of all slice data within the human body part.

[0043] Among them, the three dimensions defined by the three-dimensional coordinate system can include: X-axis dimension, Y-axis dimension and Z-axis dimension. It should be understood that the dimensions and slice positions of the slice data of each dimension can be based on the three-dimensional coordinate system defined by the CT device itself. Of course, it can also be projected into other three-dimensional coordinate systems (such as the three-dimensional coordinate system constructed when displaying the three-dimensional slice model) according to actual needs, so as to render the slice image in the display interface of the electronic device. This is not limited to this embodiment of the present disclosure.

[0044] In step S12 , slice data at the target slice position is determined according to the target slice position and slice position information respectively specified in three dimensions.

[0045] The target slice position can be understood as the slice position of the human body part where the user desires to display the slice image. In one possible implementation, the user can pre-specify the target slice position in the 3D coordinate system of the 3D slice model. For example, the user can set the coordinate position on each of the three coordinate axes of the 3D coordinate system, and use the set coordinate position as the target slice position.

[0046] In one possible implementation, in order to enable users to more conveniently view slice images at different target slice positions, a position adjustment control for adjusting the target slice position can be provided in the display interface. Users can use the position adjustment control to specify different target slice positions in different dimensions, thereby making it easier for users to view slice images at different target slice positions in different dimensions. Figure 3 A schematic diagram of a position adjustment control according to an embodiment of the present disclosure is shown. Figure 3 As shown, the user can specify the target slice position in three dimensions by adjusting the position of the "hollow circle" in each dimension on the line segment.

[0047] As mentioned above, the slice position information includes the slice positions of all slice data within the human body part. Then, based on the target slice positions and slice position information specified in three dimensions, the slice data at the target slice positions specified in three dimensions can be obtained, which is convenient for displaying the three-dimensional slice model of the human body part using the target slice positions specified in three dimensions.

[0048] In step S13, a three-dimensional slice model of the human body part is displayed according to the slice data at the target slice position. The three-dimensional slice model includes a slice image of the human body part at the target slice position rendered according to the slice data.

[0049] As described above, the slice data can be understood as the three-dimensional data required for rendering the slice image. Displaying a three-dimensional slice model of a human body part based on the slice data at the target slice position can be understood as rendering a slice image of the human body part at the target slice position on the display interface of an electronic device based on the slice data at the three target slice positions in three dimensions. It should be understood that those skilled in the art can use rendering technologies known in the art, such as the open source three.js technology, to render the slice image based on the slice data, and this is not limited to the embodiments of the present disclosure. Figure 4 A schematic diagram of a three-dimensional slice model according to an embodiment of the present disclosure is shown as follows: Figure 4 As shown, the three-dimensional slice model includes three slice images in three dimensions.

[0050] It should be understood that at least one three-dimensional scanning data of a human body part can be obtained through the above-mentioned step S11, such as three-dimensional scanning data of the same human body part of the same person at different times, or three-dimensional scanning data of the same human body part of different people. In this way, according to steps S12-S13, at least one three-dimensional slice model can be displayed in the display interface, which can facilitate the user to compare different three-dimensional slice models of the human body part at the same time.

[0051] In an embodiment of the present disclosure, by specifying the target slice position and slice position information in three dimensions, the slice data at the target slice position is determined, and a three-dimensional slice model of the human body part is displayed based on the slice data at the target slice position. The slice images at the three target slice positions specified by the user in three dimensions can be displayed simultaneously in the three-dimensional slice model, so that the user can view the slice images at different target slice positions more conveniently and intuitively.

[0052] As described above, the user can use the position adjustment control to specify different target slice positions in different dimensions, so that the user can view the slice images at different target slice positions in different dimensions. In one possible implementation, the slice data at the target slice position is determined based on the target slice positions and slice position information specified in three dimensions, including: in response to receiving a slice position adjustment instruction for the target dimension, determining the slice data at the target slice position under the target dimension indicated by the slice position adjustment instruction.

[0053] Among them, the target dimension can be understood as the dimension of the target slice position adjusted by the user. The target dimension can be any dimension of the three dimensions. For example, the user uses the above-mentioned position adjustment control to adjust the target slice position in the X-axis dimension, then the X-axis dimension can be the target dimension, and the operation of moving the "hollow circle" corresponding to the X-axis dimension in the above-mentioned position adjustment control can be understood as issuing a slice position adjustment instruction on the X-axis dimension. The position of the "hollow circle" on the line segment corresponds to the target slice position indicated by the slice position adjustment instruction in the X-axis dimension.

[0054] Among them, the slice position adjustment instruction can indicate the target slice position under the target dimension, that is, obtain the target slice position specified under the target dimension. According to the target slice position under the target dimension indicated by the slice position adjustment instruction and the above-mentioned slice position information, the slice data at the target slice position under the target dimension indicated by the slice position adjustment instruction can be determined.

[0055] It should be understood that the above-mentioned method of issuing slice position adjustment instructions using the position adjustment control is an implementation method provided by the embodiment of the present disclosure. In fact, those skilled in the art can design and implement various implementation methods of slice position adjustment instructions. For example, they can also directly set the coordinate position, etc., and the embodiment of the present disclosure does not limit this.

[0056] After determining the slice data at the target slice position within the target dimension indicated by the slice position adjustment instruction, in one possible implementation, displaying a three-dimensional slice model of the human body part based on the slice data at the target slice position includes rendering a slice image of the human body part at the target slice position within the target dimension based on the slice data at the target slice position within the target dimension indicated by the slice position adjustment instruction. In this manner, slice images at different target slice positions within different dimensions can be conveniently displayed.

[0057] As described above, those skilled in the art can adopt rendering techniques known in the art to render slice images based on slice data; the target dimension can be any of the three dimensions. It should be understood that when the three-dimensional slice model is displayed in the display interface for the first time, the three-dimensional slice image can be rendered according to the preset default slice positions in the three dimensions. When the user adjusts the target slice position in the target dimension, the slice image in the target dimension can be re-rendered in the three-dimensional slice model, and the slice images in other dimensions do not need to be re-rendered.

[0058] Figure 5 A schematic diagram of a three-dimensional slice model according to an embodiment of the present disclosure is shown as follows: Figure 5 and Figure 4 The slice diagrams at different target slice positions in three dimensions are shown in FIG. It should be understood that the slice diagrams can be obtained by Figure 5 Adjust to Figure 4 , or it can be Figure 4 Adjust to Figure 5 , this disclosure does not limit the embodiments thereof.

[0059] In the embodiment of the present disclosure, the user can adjust the target slice position to display slice images at different target slice positions in three dimensions in the three-dimensional slice model, allowing the user to more conveniently view slice images in different dimensions at the same time.

[0060] Considering that displaying three-dimensional slice images in the form of a three-dimensional slice model may still not intuitively reflect the relative positions of the slice images in each dimension relative to the human body part, in one possible implementation, the three-dimensional scan data also includes organ contour information and organ position information of at least one organ in the human body part, and the method further includes:

[0061] Based on the organ contour information and organ position information of at least one organ, a 3D image block corresponding to the at least one organ is rendered in the 3D slice model. Each 3D image block has a similar outline to the respective organ, and the display position of each 3D image block in the 3D slice model corresponds to the actual position of the respective organ within the human body. This method allows users to intuitively view the relative position of the slice images at different target slice positions relative to the human body part, and also facilitates the user to understand the slice content displayed by the slice images at different target slice positions.

[0062] The organ contour information may represent the outer contour of an organ within a human body part, and the organ position information may represent the actual position of the organ within the human body part. It should be understood that the user may pre-set the organ type (e.g., the liver or pancreas within the human abdomen) for which the 3D image blocks are to be displayed in the 3D slice model. The organ contour information and organ position information may be information extracted from the 3D scan data based on the user-set organ type, respectively, and this is not limited in the present embodiment.

[0063] It should be understood that after the organ contour information and organ position information of at least one organ are known, the rendering technology known in the art can be used to render the three-dimensional blocks corresponding to at least one organ in the three-dimensional slice model. The three-dimensional blocks are fixed relative to the slice images in the three-dimensional slice model. The slice images of different target slice positions can be displayed in the three-dimensional slice model, which makes it easy for users to intuitively view the relative positions of the slice images at different target slice positions relative to the organs in the human body.

[0064] Considering that users may need to hide certain displayed 3D tiles and / or display certain hidden 3D tiles, in one possible implementation, the method further includes: in response to receiving a hide instruction for a displayed 3D tile, hiding the 3D tile indicated by the hide instruction in the 3D slice model; and / or, in response to receiving a show instruction for a hidden 3D tile, rendering the 3D tile indicated by the show instruction in the 3D slice model. In this way, users can easily randomly display or hide 3D tiles of organs.

[0065] Among them, the hiding instruction can indicate the three-dimensional block to be hidden, and when the hiding instruction is received, the three-dimensional block indicated by the hiding instruction can be hidden; the display instruction can indicate the three-dimensional block to be displayed, and when the display instruction is received, the three-dimensional block indicated by the display instruction can be redisplayed.

[0066] It should be understood that those skilled in the art can design and develop triggering methods for hiding instructions and display instructions according to actual needs. For example, by providing a hiding button and / or a display button in the display interface, it is convenient for users to use the hiding button and / or the display button to issue hiding instructions and / or display instructions. This is not limited to the embodiments of the present disclosure.

[0067] In one possible implementation, to facilitate differentiation between 3D image blocks of different organs, the 3D image blocks of different organs may use different colors and / or different transparencies. That is, the 3D image blocks corresponding to different organs within a human body region may have different display effects, where the display effects include at least one of color and transparency. The method further includes:

[0068] In response to receiving a color adjustment instruction for a 3D tile, the color of the 3D tile indicated by the color adjustment instruction is converted to the target color indicated by the color adjustment instruction; and / or in response to receiving a transparency adjustment instruction for the 3D tile, the transparency of the 3D tile indicated by the transparency adjustment instruction is converted to the target transparency indicated by the transparency adjustment instruction. In this way, users can easily customize the display effect of the 3D tile.

[0069] It should be understood that those skilled in the art can design and develop triggering methods for color adjustment instructions and transparency adjustment instructions according to actual needs. For example, an input box control can be provided after the user selects any three-dimensional block to receive the color value of the target color, the numerical value of the target transparency, etc. entered by the user through the input box control. This is not limited to the embodiments of the present disclosure.

[0070] Considering that the 3D slice model can display slice images in three dimensions simultaneously, users may need to only view slice images in a certain dimension. In one possible implementation, the 3D slice model has at least one viewing angle mode among a 3D perspective, a horizontal perspective, a vertical perspective, and a vertical perspective. The 3D perspective is used to display slice images in three dimensions simultaneously, the horizontal perspective is used to display horizontal slice images in the X-axis dimension, the vertical perspective is used to display vertical slice images in the Y-axis dimension, and the vertical perspective is used to display vertical slice images in the Z-axis dimension.

[0071] The 3D slice model is currently displayed in any viewing mode. In one possible implementation, the method further includes: in response to receiving a viewing angle switching instruction for the 3D slice model, controlling the 3D slice model to transform to a target viewing angle indicated by the viewing angle switching instruction. In this manner, it is convenient for a user to view slice images in different viewing angles.

[0072] The target perspective mode can be understood as a perspective mode indicated by the perspective switching instruction, which is different from the currently displayed perspective mode. It should be understood that those skilled in the art can design and develop a triggering method for the perspective switching instruction according to actual needs. For example, a perspective switching button can be provided in the display interface to facilitate the user to issue the perspective switching instruction through the perspective switching button, and this embodiment of the present disclosure is not limited to this.

[0073] Figure 6 A schematic diagram of a three-dimensional slice model according to an embodiment of the present disclosure is shown as follows: Figure 6 What is shown is a three-dimensional slice model under a vertical cutting perspective, which can display a vertical slice image on the Z axis. It should be understood that Figure 6 The three-dimensional slice model shown may also be a transverse perspective or a longitudinal perspective, which may be specifically determined according to the directions of the three coordinate axes in the three-dimensional coordinate system corresponding to the three-dimensional slice model, and this embodiment of the present disclosure does not limit this.

[0074] Among them, each perspective model can be preset to have a default posture. When the three-dimensional slice model switches from the current perspective mode to the target perspective mode, the current posture of the three-dimensional slice model is adjusted to the default posture corresponding to the target perspective mode, thereby controlling the three-dimensional slice model to transform into the target perspective mode indicated by the perspective switching instruction.

[0075] Considering that, in addition to the default poses for the four viewing modes described above, users may also need to view the 3D slice model in a custom pose. In one possible implementation, the method further includes: in response to receiving a pose adjustment instruction for the 3D slice model, transforming the 3D slice model to a target pose indicated by the pose adjustment instruction. This method facilitates the user's ability to adjust the 3D slice model to a custom target pose, allowing the user to view the 3D slice model in different poses.

[0076] Considering that users may also need to adjust the brightness and darkness contrast of different slice tissues in the slice image to highlight certain slice tissues, in one possible implementation, the method further includes: in response to receiving a brightness and darkness adjustment instruction for the slice image in the three-dimensional slice model, adjusting the brightness and darkness contrast of the different slice tissues in the slice image according to at least one of brightness and contrast indicated by the brightness and darkness adjustment instruction. In this way, users can easily customize the brightness and darkness contrast of different slice tissues in the slice image.

[0077] Among them, adjusting the light and dark contrast effects of different slice tissues in the slice image according to at least one of the brightness and contrast indicated by the light and dark adjustment instruction can be understood as re-rendering each slice image in the three-dimensional slice model according to at least one of the brightness and contrast indicated by the light and dark adjustment instruction, so that the light and dark contrast effects of different slice tissues in each re-rendered slice image match the brightness and / or contrast indicated by the light and dark adjustment instruction.

[0078] It should be understood that those skilled in the art can design and develop a triggering method for brightness adjustment instructions according to actual needs. For example, a brightness adjustment control can be provided in the display interface in the manner of the above-mentioned position adjustment control to facilitate users to issue brightness adjustment instructions through the brightness adjustment control. This is not limited to the embodiments of the present disclosure.

[0081] It should be understood that the above Figure 8 The control panel shown is an implementation method provided by the embodiment of the present disclosure. Those skilled in the art can customize the design of the control panel and the functional controls contained in the control panel according to actual needs. For example, a control for modifying the name of a three-dimensional block can also be designed, and this embodiment of the present disclosure does not limit this.

[0082] Considering that the 3D data visualization method in related technologies usually downloads the 3D data to a local computer and loads the 3D data using locally installed 3D software, this method is not convenient for viewing 3D slice models. The process of opening 3D slice models is relatively complicated and resource-intensive. The disclosed embodiment provides a method for viewing 3D slice models through a front-end browser. That is, 3D scan data can be loaded from a back-end server and the 3D slice model can be rendered through the front-end browser. In this way, the 3D slice model can be viewed online through the browser without the need for local installation of 3D software, which improves the convenience of viewing 3D slice models.

[0083] In a possible implementation, the three-dimensional data display method is applied to a front-end browser. In step S11, three-dimensional scanning data of a human body part is obtained, including:

[0084] Obtaining original three-dimensional scanning data in an original data format sent by a back-end server; converting the original three-dimensional scanning data into three-dimensional scanning data in a preset data format; and extracting at least one of the following information from the three-dimensional scanning data in the preset data format: slice data of a human body part in three dimensions, slice position information of the slice data in three dimensions, and organ contour information and organ position information of at least one organ in the human body part.

[0085] In one possible implementation, the original data format may adopt the Protobuf format (a data description language that can serialize structured data); wherein, the user can use the Protobuf technology to customize the data format, and the data format constructed using the Protobuf technology can be called the Protobuf format, so as to facilitate data interaction between the front-end browser and the back-end database.

[0086] It is known that when using Protobuf to customize the data format, a Protobuf definition file proto file is usually generated. The proto file contains the interaction data agreed upon by the front-end and back-end for data interaction and the parsing method of the interaction data. Generally, the front-end browser can pre-acquire the Protobuf definition file proto file. After the front-end browser receives the .proto file, it can, for example, use the local open source library grpc-tools and @grpc / grpc-js to convert the .proto file into a specific data access class file (such as a .js file), and add the data access class file to the local program. In this way, the method in the data access class file is used to parse the interaction data in the Protobuf format (such as the original three-dimensional scanning data with the original data format mentioned above). For example, the deserialization binary method in the data access class file is used to deserialize the original three-dimensional scanning data into three-dimensional scanning data with a preset data format, and then the object data acquisition method in the data access class file is used to extract at least one of the above information from the three-dimensional scanning data.

[0087] As described above, the preset data format can be a data format that can be recognized by the browser when rendering the slice image. The preset data format can be, for example, the Vis3D format, which is not limited to this embodiment of the present disclosure. That is, the slice data extracted from the three-dimensional scanning data has the above-mentioned Vis3D format, which is convenient for rendering the slice image based on the slice data.

[0088] As mentioned above, the three-dimensional scanning data can be the data obtained by the CT device scanning the human body part. In order to facilitate the online viewing of the three-dimensional slice model of the human body part through the browser, the CT device can upload the three-dimensional scanning data obtained by the scan to the back-end server. This makes it convenient to obtain the three-dimensional scanning data online from the back-end server through the front-end browser, and display the three-dimensional slice model based on the three-dimensional scanning data.

[0089] In the disclosed embodiment, online visualization of three-dimensional scanning data is realized, and Vis3D format files can be viewed directly in the browser; it supports uploading three-dimensional scanning data to the back-end server, and after uploading, the three-dimensional slice model can be viewed directly online in the browser, which improves the convenience of users viewing the three-dimensional slice model.

[0090] According to the embodiments of the present disclosure, online viewing of three-dimensional scanning data can be realized. Compared with the related art of downloading the three-dimensional scanning data to the local and viewing it using three-dimensional software, the environmental configuration cost required for viewing the three-dimensional scanning data is reduced, and at least two three-dimensional slice models can be rendered simultaneously on a display interface for users to compare and view.

[0091] According to the embodiments of the present disclosure, it can also be applied to a network model training system, which can view the training effect of the network model during network model training. The network model can be used to generate a three-dimensional slice model, thereby improving the development efficiency of the network model.
