[0053] The following is combined with Figure 1 This application is described in further detail.

[0054] The first aspect of the present application provides a method for quickly constructing an interactive panoramic virtual aircraft cockpit, comprising the following steps:

[0055] Step 1: Obtain a lightweight three-dimensional design model of the cockpit according to the aircraft data structure;

[0056] Step 2: Perform data cleaning and format conversion on the lightweight 3D design model of the cockpit;

[0060] Step 6: Design interactive hotspots and interactive interfaces for the cockpit panorama;

[0061] Step 7: Generate an interactive panoramic virtual aircraft cockpit based on the cockpit panoramic image, interactive hotspots and interactive interface.

[0062] In a preferred embodiment of the present application, in step 1, first, a lightweight three-dimensional design model of a cockpit is obtained according to an aircraft data structure, specifically including:

[0063] According to the aircraft data structure, the cockpit 3D design data is filtered out from the product database by aircraft model, aircraft section, and top-level drawing number;

[0064] Convert cockpit 3D design data into cockpit lightweight 3D design model.

[0065] Obtaining complete and correct cockpit 3D design data is a prerequisite for subsequent verification and review work. Through menu-based hierarchical data screening, including aircraft model screening, aircraft section (cockpit) screening and specific top-level drawing number screening, the 3D design data of the finished product, structure, system, interior, etc. of the aircraft cockpit is obtained from the product database. At the same time, in order to ensure the efficiency and fluency of subsequent work, the data storage end background automatically converts the cockpit 3D design data into a lightweight cockpit 3D design model on a regular basis, and then provides users with a fast download service for the latest 3D design model data.

[0066] In a preferred embodiment of the present application, in step 2, data cleaning and format conversion are performed on the lightweight three-dimensional design model of the cockpit, including:

[0067] Clean up all blocked and invisible cockpit lightweight 3D design models;

[0068] Batch convert cockpit lightweight 3D design models into a format compatible with virtual reality software.

[0069] All the blocked and invisible cockpit lightweight 3D design models can be cleaned manually to ensure the original design structure tree; OpenGL layer can also be used to quickly capture the visual model, automatically clean all the blocked and invisible cockpit lightweight 3D design models, and quickly obtain the available cockpit lightweight 3D design models, but the original design structure tree will be lost. By batch converting the cockpit lightweight 3D design model data into a format that can be used by virtual reality software, preparation is made for building a 3D virtual cockpit in step three.

[0070] In a preferred embodiment of the present application, in step 3, based on the lightweight 3D design model of the cockpit, a 3D virtual cockpit is quickly constructed and rendered using a virtual reality environment, including:

The entire cockpit environment that can reflect real lighting is quickly generated using real-time lighting rendering technology. Using virtual reality display systems and equipment, such as immersive CAVE systems and head-mounted display devices, users are placed in the virtual environment of the cockpit to conduct preliminary verification of cockpit layout, material, color matching and other schemes.

[0079] According to the three-dimensional virtual cockpit and the panoramic browsing route, a cockpit panorama of rectangular spherical projection with real-time lighting rendering is generated by cameras at all panoramic viewpoints.

[0080] Among them, high-resolution cockpit panoramas in the form of cross or rectangular spherical projections with real-time lighting rendering are quickly generated by cameras at all panoramic viewpoints. For the panorama of the cross projection, the six faces of the cube it wraps are included: front, back, left, right, top, and bottom. In the actual generation, the corresponding suffix needs to be added to distinguish. The rendering resolution of each face can be set to 4000 pixels × 4000 pixels or above, and the plane is stitched into a high-resolution cross-projected panorama that meets the subsequent detailed scaling verification. For the panorama of the rectangular spherical projection, the aspect ratio must be 2:1, and the rendering resolution can be set to 8000 pixels × 4000 pixels or above.

[0081] In a preferred embodiment of the present application, in step 6, designing interactive hotspots and interactive interfaces for the cockpit panoramic view includes:

[0082] Perform skin editing in the cockpit panorama, design interactive hotspots for switching cockpit panoramas with different panoramic viewpoints and for triggering information, and design an interactive interface with page zoom, full screen, and VR status functions.

[0083] Among them, by editing the skin in the panoramic design environment and saving the designed interactive hotspots and interactive interfaces as configuration files, quick and convenient reuse can be achieved between different cockpit projects.

[0084] In a preferred embodiment of the present application, after step seven of generating the interactive panoramic virtual aircraft cockpit, step eight is also included, packaging the generated interactive panoramic virtual aircraft cockpit into an HTML web page format and arranging it on a server or a user terminal, thereby achieving rapid response of the interactive panoramic virtual aircraft cockpit.

You can also use virtual reality peripherals, such as head-mounted display devices, for immersive interactive browsing.

It can be deployed on a server or directly opened locally on any user terminal. It is basically not limited by software and hardware configurations, and can respond quickly and run smoothly. It solves the problems of slow response, excessive data volume, and high hardware configuration requirements when the three-dimensional design data of the aircraft cockpit is verified, displayed, and reviewed in real time.
