[0029] Example 1

[0030] Figure 1 A flowchart of a cloud rendering method of an aircraft component is provided for the embodiments of the present application. The embodiments can be applicable to the cloud rendering of aircraft component images. The method can be executed by a cloud rendering device of an aircraft component. The device can be implemented in the form of hardware and / or software and configured in various computers or servers.

[0031] As shown in Figure 1 , it includes:

[0032] Step 110, obtaining a rendering request of a client, the rendering request including an interactive operation for a to-be-rendered aircraft component.

[0033] The rendering request is a control request of a user for the to-be-rendered aircraft component, which can represent the interactive operation of the user on the to-be-rendered aircraft component. The rendering request can be generated based on the interactive operation input by the input device of the client. The interactive operation is, for example, mouse clicking, mouse moving, scroll wheel scrolling, or keyboard input. The interactive operation is used to control the to-be-rendered aircraft component to deform or displace, such as magnification, rotation, reduction, and displacement of the to-be-rendered aircraft component.

[0034] For example, the rendering request of the client can be obtained through the web browser of the client.

[0035] Specifically, the user can interact with the to-be-rendered aircraft component on the client, the client generates a corresponding rendering request, and then sends the rendering request to the cloud. The cloud performs rendering operation according to the rendering request, and then returns the rendered image to the client.

[0036] Step 120, determining a to-be-rendered aircraft component and corresponding control information according to the rendering request.

[0037] The to-be-rendered aircraft component is the target aircraft component to be rendered by the user. The control information can be an interactive operation or a control command for the to-be-rendered aircraft component, such as magnification, rotation, reduction, and displacement. The control information also includes operation time and operation action information of various interactive operations.

[0038] Specifically, the cloud can determine the to-be-rendered aircraft and the control information for the to-be-rendered aircraft component by analyzing the rendering request. Different control information will have different image rendering results, such as magnification action rendering or rotation action rendering of the to-be-rendered aircraft component.

[0039] Step 130, determining a target rendering model from candidate rendering models of the to-be-rendered aircraft component according to the control information, wherein the candidate rendering models represent at least two groups of rendering data of the to-be-rendered aircraft component with different rendering data amounts.

[0040] The candidate rendering model includes at least two groups of rendering data required for rendering the aircraft components, the data amount of different groups of rendering data is different, and the rendering effect of the aircraft components corresponding to different rendering data is different, such as different picture quality and picture resolution.

[0041] Specifically, because the rendering quality required by different aircraft components, different rendering requirements and different interactive operations is different, at least two groups of rendering data amount models can be preset, and then different rendering models with different rendering data amount are selected to achieve the purpose of reducing the calculation amount.

[0042] Optionally, the candidate rendering model includes a first rendering model and a second rendering model; and the generation method of the candidate rendering model includes:

[0043] obtaining a first data format file and a second data format file of the aircraft component, wherein the first data format file is a physical attribute file of the aircraft component, and the second data format file is a space structure file of the aircraft component;

[0044] determining a mapping relationship of the first data format file and the second data format file;

[0045] updating the corresponding second data format file by using the first data format file according to the mapping relationship, to generate a second data format update file;

[0046] generating a second rendering model according to the second data format update file, performing discretization processing on the second rendering model, and generating a first rendering model.

[0047] The physical attribute file of the aircraft component can include the part composition of the aircraft component, the weight, material and version of each part, and the space structure file of the aircraft component includes the mathematical expression of the space coordinates of each aircraft component and part; the mapping relationship can be established by the ID, name or unique identifier of the aircraft component, which is not limited here; the discretization can be realized by image discretization algorithm, such as Fourier transform.

[0048] Specifically, different data format files contain different aircraft component attribute contents, and the content contained in the extended file can improve the accuracy of rendering. Therefore, the first data format file can be used to update the corresponding second data format file to generate a second data format update file to supplement the second data format file. The second data format update file contains all the contents of the first data format file and the second data format file. Further, the second rendering model can be generated according to the second data format update file for the rendering work of the aircraft component to be rendered. Further, the second rendering model can be discretized to generate the first rendering model, so that two rendering models with different rendering data amounts can be obtained, and different rendering models can be used according to the rendering requirements to improve the rendering efficiency. For example, when the aircraft component is scaled down, the required rendering picture quality requirement is low, and therefore the first rendering model with low rendering data amount can be used. When the aircraft component is scaled up, a more accurate rendering image is required, and therefore the second rendering model can be used for rendering operation to improve the accuracy of the rendering image.

[0049] For example, the physical attribute file of the aircraft component can be an MBD data file, which can specifically include an MBD definition structure, MBD elements, and MBD attribute metadata. For example, the MBD definition structure includes all sub-components of the aircraft component, the MBD elements include specifications, starting points, and ending points of each sub-component, and the MBD attribute metadata includes the weight and material of the component.

[0050] For example, the spatial three-dimensional geometric structure file of the aircraft component can be a STEP (Standard for the Exchange of Product Data) file. STEP is an international standard file format used for exchanging product data between different CAD systems. The STEP file contains the mathematical expression of each aircraft component. The STEP format can ensure that design details and manufacturing specifications are correctly understood and used at every stage of the supply chain. For example, an aircraft manufacturer can use a STEP file to share component designs with suppliers to ensure that components can be accurately manufactured and meet design specifications.

[0051] Optionally, the target rendering model is determined according to a preset operation model corresponding table corresponding to the interaction operation represented by the control information, wherein the preset operation model corresponding table includes a corresponding relationship between the interaction operation and the rendering model category.

[0052] Specifically, the corresponding relationship is that different interaction operations correspond to different rendering model categories.

[0053] Exemplarily, the corresponding relationship can be that, if the interaction operation represents a zoom-in operation, the picture quality requirement of the rendered image is high, and therefore, the second rendering model with a larger amount of rendering data can be selected; if the interaction operation represents a rotation or a translation, the picture quality requirement of the rendered image is low, and therefore, the first rendering model with a smaller amount of data can be selected.

[0054] Optionally, the interaction operation includes a mouse interaction operation, and the determining of the aircraft part to be rendered and the corresponding control information according to the rendering request includes:

[0055] parsing the rendering request to determine the mouse click point and the control information;

[0056] determining a mouse selection ray pointing to the three-dimensional view of the aircraft part according to the coordinates of the mouse click point and a preset direction;

[0057] determining the first subpart intersected by the mouse selection ray and the three-dimensional view of the aircraft part as the aircraft part to be rendered.

[0058] wherein the mouse click point is a click operation of a user on the aircraft part to be rendered on the client side; the mouse selection ray is a virtual ray, because the aircraft part is a three-dimensional view in space, but the operation screen is a two-dimensional view, therefore, when the user clicks on the operation screen, a plurality of aircraft parts of a uniform height are clicked, and therefore, a ray, i.e., the mouse selection ray, is needed to be determined from the coordinates of the mouse click point, the intersection point of the mouse selection ray and the three-dimensional view of the aircraft part is determined, and then the aircraft part to be rendered is determined; the preset direction can be perpendicular to the screen direction, or other preset angles, which are not limited herein.

[0059] Specifically, when the server receives the rendering request of the user on the aircraft part to be rendered, the mouse click point and the control information can be determined by parsing the rendering request, and then the mouse selection ray can be constructed according to the coordinates of the mouse click point and the preset direction, and then the first subpart intersected by the mouse selection ray and the three-dimensional view of the aircraft part is determined as the aircraft part to be rendered.

[0060] Exemplarily, the coordinates of the mouse click point are (x0, y0, 0), and the preset angle is 90 degrees, and the equation of the mouse selection ray is wherein t is a real number, and further, the first subpart intersected by the mouse selection ray and the three-dimensional view of the aircraft part is determined as the aircraft part to be rendered.

[0061] In step 140, the aircraft part to be rendered is rendered based on the target rendering model, a rendered video frame is generated, and the rendered video frame is sent to the client side.

[0062] Specifically, a rendering server can be used to render the target rendering model to generate a rendered video frame, and then the rendered video frame is sent to the client to complete the rendering task.

[0063] The embodiment of the application provides a cloud rendering method for an aircraft component, which comprises the following steps: obtaining a rendering request of a client, wherein the rendering request comprises an interactive operation for an aircraft component to be rendered; determining the aircraft component to be rendered and corresponding control information according to the rendering request; determining a target rendering model from candidate rendering models of the aircraft component to be rendered according to the control information, wherein the candidate rendering models represent at least two groups of rendering data of the aircraft component to be rendered, and the rendering data has different data amounts; and rendering the aircraft component to be rendered based on the target rendering model, generating a rendered video frame, and sending the rendered video frame to the client. Specifically, the aircraft component to be rendered and the corresponding control information can be determined by analyzing the rendering request, and then the target rendering model can be determined through the interactive operation corresponding to the control information. Since different interactive operations correspond to different rendering models, and the rendering data of different rendering models has different data amounts, the method of the embodiment of the application can determine different rendering models according to the rendering request, so as to reduce the rendering data amount and the rendering time, and improve the rendering efficiency. Furthermore, the mouse click point can be determined by analyzing the rendering request, and then the mouse selection ray can be determined according to the mouse click point, and finally the aircraft component to be rendered can be determined. This method can accurately and quickly determine the aircraft component to be rendered by the user in the cloud, so as to improve the rendering efficiency.

[0064] Embodiment two

[0065] Figure 2 A flowchart of a cloud rendering method for an aircraft component is provided for the embodiment two of the application. The method is based on the above-mentioned embodiment, and further limits the specific method for sending the rendered video frame to the client, as shown in Figure 2 , which comprises the following steps:

[0066] Step 210: obtaining a rendering request of a client, wherein the rendering request comprises an interactive operation for an aircraft component to be rendered.

[0067] Step 220: determining the aircraft component to be rendered and corresponding control information according to the rendering request.

[0068] Step 230: determining a target rendering model from candidate rendering models of the aircraft component to be rendered according to the control information, wherein the candidate rendering models represent at least two groups of rendering data of the aircraft component to be rendered, and the rendering data has different data amounts.

[0069] Step 240: rendering the aircraft component to be rendered based on the target rendering model, generating a rendered video frame.

[0070] Optionally, before rendering by the target rendering model, further comprising:

[0071] determining load information of each rendering server, and determining the target rendering server according to the load information;

[0072] the rendering of the aircraft component to be rendered based on the target rendering model comprises:

[0073] sending the target rendering model to the target rendering server, and controlling the target rendering server to render the aircraft component to be rendered.

[0074] The rendering server is configured to generate a rendered video frame based on the target rendering model, and the rendering server comprises a rendering graphics card and a CPU. The load information comprises residual computing resources of the rendering graphics card and the CPU in each rendering server.

[0075] Specifically, the rendering server with the most residual computing resources can be determined as the target rendering server according to the load information, and then the target rendering server is used to render the aircraft component to be rendered, so as to reduce the rendering time and balance the use of resources.

[0076] Step 250: determining an interaction time corresponding to the rendered video frame according to the control information.

[0077] The interaction time is used to represent an interaction process of the interaction operation, and the interaction time comprises an interaction start and end time and an interaction intermediate time. The interaction start and end time is a time when the interaction operation starts and ends, and the interaction intermediate time is each time between the interaction start and end time.

[0078] Step 260: determining a category of the rendered video frame according to the interaction time, wherein the category of the rendered video frame comprises an intermediate process frame or a static frame, and the compressed quality of the rendered video frame of different categories is different.

[0079] The frame corresponding to the interaction start and end time is a static frame, and the frame corresponding to the interaction intermediate time is an intermediate process frame.

[0080] Specifically, the control information is analyzed. If it is determined that the interaction time corresponding to the rendered video frame is the start time or the end time of the interaction operation, the rendered video frame is determined as a static frame. If it is determined that the interaction time corresponding to the rendered video frame is the intermediate time of the interaction operation, the rendered video frame is determined as an intermediate process frame.

[0081] Specifically, since the rendered video is a continuous video image, when the client performs rotation, translation or scaling on the aircraft component, only at the beginning and end of the interactive operation, the user needs to see a clear and complete image, and the image in the middle process can be a blurred image, therefore, the interactive time corresponding to the rendered video frame can be determined by analyzing the control information, and then the category of the rendered video frame is determined according to the interactive time corresponding to the rendered video frame, and then the static frame corresponding to the start and end time of the interaction can be set to have a higher compression quality, and the intermediate process frame corresponding to the intermediate time of the interaction can be set to have a lower compression quality, so as to improve the transmission efficiency.

[0082] Step 270, determining the compression quality of the rendered video frame according to the category of the rendered video frame.

[0083] Optionally, if the category of the rendered video frame is an intermediate process frame, the compression quality of the rendered video frame is determined as a first compression quality, otherwise, as a second compression quality, wherein the first compression quality is less than the second compression quality.

[0084] Step 280, compressing the rendered video frame according to the compression quality, and sending the compressed rendered video frame to the client.

[0085] Wherein, the range of compression quality is 0-100%, and the image quality of 100% compression quality is the highest, and 0 is full loss compression.

[0086] Specifically, the operation time in the interactive operation process can be determined by analyzing the control information, and then the time of initiating the interactive operation and the time of ending the interactive operation are determined as the start and end time of the interaction, and the time between the start and end time of the interaction is determined as the intermediate time of the interaction, and then the static frame representing the start and end time of the interaction uses the second compression quality with higher compression quality, and the intermediate process frame representing the intermediate process of the interactive operation uses the first compression quality with lower compression quality. In this way, the amount of resources required for transmission can be reduced, and the transmission efficiency can be improved.

[0087] For example, when the aircraft component is rotated, the aircraft component needs to be clicked and the mouse needs to be pressed to rotate, and finally the mouse is released to end the rotation, and then the time of clicking and releasing can be determined as the start and end time, and the rendered video frame corresponding to the time is a static frame, and the time between the start and end time corresponds to the rendered video frame of the intermediate process frame.

[0088] The embodiment of the application provides a cloud rendering method of an aircraft component, by analyzing the control information of the aircraft component to be rendered, whether the current rendered video frame is the start and end time can be determined, and then the rendered video frame is determined as a static frame, and the second compression quality is used for compression, otherwise, the first compression quality is used for compression, in this way, the compression speed of the rendered video frame can be improved, and the amount of data required for transmission can be saved.
