Description

Technical Field

[0001] The present invention relates to the technical field of mixed reality for the design of photovoltaic power stations, and particularly to a method for producing panoramic animations in the pre-construction stage of rooftop photovoltaic power stations. Background Art

[0002] The panoramic animation in the pre-construction stage of a photovoltaic power station based on a digital twin model management platform is a new type of digital design integration and display mode. By using the technology of video plus real-scene twin, users can interact with virtual objects in the real environment to achieve a more realistic display effect. Customers can more intuitively and accurately understand the project plan, the photovoltaic roof structure, and the pre-construction effect through the animation display, improving the communication efficiency between technicians and customers, thereby promoting the project progress, reducing the time costs of customers, companies, and designers, and maximizing the interests of the three parties.

[0003] Currently, the existing photovoltaic engineering project displays still mainly use two-dimensional floor plans and renderings for reporting, supplemented by three-dimensional models and animations. However, the traditional photovoltaic project display mainly uses two-dimensional renderings, with insufficient display of project details, and the model rendering effect is not realistic enough. It cannot combine virtual photovoltaic components with the actual environment, resulting in poor visualization effects. Secondly, traditional photovoltaic designs cannot display project details, structures, and effects from multiple dimensions. Customers' understanding of project designs is not direct, clear, and accurate enough. Moreover, the flat display is more boring and has less sense of participation than the animation display, which will affect the interactivity between customers and projects. In addition, photovoltaic engineering projects involve a lot of professional field knowledge and terms, which are difficult for customers to understand. The traditional flat display form will greatly increase the communication difficulty and understanding error, and seriously prolong the project cycle, resulting in low communication efficiency. Summary of the Invention

[0004] Aiming at the above three problems, the purpose of the present invention is to propose a method for producing panoramic animations in the pre-construction stage of rooftop photovoltaic power stations. By using technical methods such as drone data acquisition technology, three-dimensional reconstruction means, 3D visualization software, and related management platforms, the problems of poor visualization effects and low communication efficiency existing in traditional photovoltaic engineering projects are solved.

[0005] It is achieved through the following technical solutions: A method for producing a panoramic animation in the pre-construction stage of a rooftop photovoltaic power station, the method comprising the following steps: S1. Use an RTK drone to capture multiple image data of the surrounding environment of the rooftop, and perform quality screening on the multiple image data through aerial triangulation technology. Import the multiple image data that meet the quality requirements into 3D reconstruction software, construct a 3D reconstruction model of the rooftop, and export it in the form of an OSGB file; S2. Open 3D modeling software, import the OSGB file of the 3D reconstruction model of the rooftop into a newly created script file. After adjusting the X, Y, and Z axes of the 3D reconstruction model of the rooftop, export the FBX format file of the 3D reconstruction model of the rooftop; S3. Select the required scene range for constructing a photovoltaic power station on the rooftop through a map service website, and export the corresponding OSM data file of the selected range. Then, perform format conversion on it through 3D modeling software to obtain and export the FBX format file of the 3D map model of the rooftop; S4. Import the FBX format files of the 3D reconstruction model of the rooftop and the 3D map model into 3D visualization software respectively, and enter the animation production interface of the 3D visualization software. Select key frames from the imported FBX format files to produce an animation of the surrounding environment of the rooftop, then export the produced animation video, upload the animation video through a relevant management platform, and share and display the rooftop photovoltaic power station project through a relevant design platform.

[0006] The method of the present invention can visually display the real effect after the pre-construction of the photovoltaic power station, can restore the photovoltaic power station project and the plan in a 1:1 manner, make the plan display more intuitive, and make project communication more efficient, solving the problems of poor visualization effect and low communication efficiency existing in traditional photovoltaic engineering projects.

[0007] Preferably, in step S1, when performing quality screening on multiple image data through aerial triangulation technology, if the proportion of the number of images that meet the quality requirements in the screened images < 95%, it indicates that the shooting quality does not meet the requirements of 3D reconstruction; if the proportion of the number of images that meet the quality requirements in the screened images ≥ 95%, it indicates that the shooting quality meets the requirements of 3D reconstruction. Screening the image data through aerial triangulation technology can obtain more accurate information about the surrounding environment of the rooftop, provide reliable image data for subsequent construction of the 3D reconstruction model of the rooftop, and significantly improve the geometric accuracy of the constructed model.

[0008] Preferably, in step S2, when adjusting the X, Y, and Z axes of the 3D reconstruction model of the rooftop, the X axis is used to adjust the left and right movement and rotation of the model; the Y axis is used to adjust the up and down movement and rotation of the model; the Z axis is used to adjust the front and back movement and depth of the model. By adjusting the X, Y, and Z axes of the 3D reconstruction model of the rooftop, the model can better fit the scene of the real rooftop photovoltaic power station, providing a more realistic display effect for customers.

[0009] Preferably, in step S4, when making the animation, the opening of the animation adopts a growth animation. Subsequently, the bird's-eye view circles around the rooftop photovoltaic power station once, then pans from the close-up view to show the detailed effect of the photovoltaic panels, and finally restores the scene of the rooftop photovoltaic power station in rainy and snowy weather. By demonstrating the effect after the pre-construction of the rooftop photovoltaic power station through animation production, the scheme can be demonstrated more intuitively, and the communication efficiency of the photovoltaic power station project can be further improved.

[0010] Preferably, in step S4, after selecting the key frames from the FBX format file, it is necessary to adjust the material parameters and animation parameters of the selected frames. By adjusting the material parameters and animation parameters of the selected frames, the overall effect of the animation production can be made closer to the real effect display, thereby improving the completion efficiency of the photovoltaic power station project.

[0011] Preferably, in step S4, when uploading the animation video through the management platform, the specific operation is as follows: Open the video management in the management platform, click on adding new video storage management, upload the animation video to be uploaded, and then click confirm. By uploading the animation video to the management platform, the animation video can be stored and managed for subsequent viewing and demonstration.

By sharing and demonstrating the designed rooftop photovoltaic power station project, the communication efficiency among project-related personnel can be improved, and the understanding and expectation deviation can be reduced.

Brief Description of the Drawings

[0015] Next, the technical solutions in the embodiments of the present invention will be described in detail with reference to the accompanying drawings in the embodiments of the present invention.

[0016] As Figure 1 shown, it is a flowchart of a method for producing a panoramic animation in the pre-construction stage of a rooftop photovoltaic power station. First, use an RTK drone to capture multiple image data of the surrounding environment of the rooftop, construct a 3D reconstruction model of the rooftop and export it in the form of an OSGB file; then, after adjusting the X, Y, and Z axes of the 3D reconstruction model of the rooftop through 3D modeling software, export the FBX format file of the 3D reconstruction model of the rooftop; secondly, select the required scene range for constructing a photovoltaic power station on the rooftop through a map service website and perform format conversion on it through 3D modeling software to obtain the FBX format file of the 3D map model; finally, perform animation production of the surrounding environment of the rooftop through 3D visualization software and share and display it; thereby realizing the visual display of the real effect after the pre-construction of the rooftop photovoltaic power station and improving the completion efficiency of the rooftop photovoltaic power station project.

[0017] The method specifically includes the following steps: S1. Use an RTK drone to capture multiple image data of the surrounding environment of the rooftop, and perform quality screening on the multiple image data through aerial triangulation technology. Import the multiple image data that meet the quality requirements into 3D reconstruction software, construct a 3D reconstruction model of the rooftop and export it in the form of an OSGB file; where OSGB stands for Open Scene Graph Binary, which is a binary file format mainly used for storing and loading 3D models. By using compression algorithms and data structure optimization, it can efficiently store and load the 3D reconstruction model of the rooftop and its related materials, textures, and geometric data.

[0018] In this embodiment, in step S1, when performing quality screening on multiple image data through aerial triangulation technology, first set the aerial triangulation parameters to perform aerial triangulation processing on the multiple image data and generate a quality report, and then judge whether each image meets the 3D reconstruction requirements through the quality report; if the proportion of the number of images that meet the quality requirements in the selected images < 95%, it means that the shooting quality does not meet the 3D reconstruction requirements and data needs to be re-collected; if the proportion of the number of images that meet the quality requirements in the selected images ≥ 95%, it means that the shooting quality meets the 3D reconstruction requirements; screening the image data through aerial triangulation technology can obtain more accurate information about the surrounding environment of the rooftop, provide reliable image data for the subsequent construction of the 3D reconstruction model of the rooftop, and significantly improve the geometric accuracy of the constructed model.

[0019] S2. Open the 3D modeling software. First, import the OSGB file of the roof 3D reconstruction model into the newly created script file. Then, adjust the center of the roof 3D reconstruction model to the coordinate axis. After adjusting the X, Y, and Z axes of the roof 3D reconstruction model, export the FBX format file of the roof 3D reconstruction model. Here, FBX stands for Flexible Body Exchange, which is a 3D general model file format. The FBX format file is based on a binary storage format, capable of efficiently storing a large amount of complex data and can be quickly imported and exported between different 3D software, greatly improving the efficiency and flexibility of the panoramic animation production process in the pre-construction stage of the rooftop photovoltaic power station.

[0020] Among them, when adjusting the X, Y, and Z axes of the roof 3D reconstruction model, the X axis is used to adjust the left-right movement and rotation of the model; the Y axis is used to adjust the up-down movement and rotation of the model; the Z axis is used to adjust the front-back movement and depth of the model. By adjusting the X, Y, and Z axes of the roof 3D reconstruction model, the model can better fit the actual rooftop photovoltaic power station scenario, providing a more realistic display effect for customers and further improving the completion efficiency of the photovoltaic power station project.

[0021] S3. Select the required scene range for building a photovoltaic power station on the roof through the map service website and export the corresponding OSM data file of the selected range. Then, by installing relevant plugins in the 3D modeling software, the format can be converted to obtain and export the FBX format file of the rooftop 3D map model. Here, OSM stands for OpenStreetMap, and the OSM data file is the map data file on the OpenStreetMap map service website, which contains geographical information, roads, buildings, rivers, and other various geographical element information around the rooftop photovoltaic power station project, so as to obtain the corresponding real-scene 3D map model and provide a more realistic scene effect for the subsequent panoramic animation production in the pre-construction stage of the rooftop photovoltaic power station.

[0022] S4. Import the FBX format files of the roof 3D reconstruction model and the 3D map model into the 3D visualization software respectively, and enter the animation production interface of the 3D visualization software. By selecting key frames from the imported FBX format files, produce the animation of the surrounding environment of the roof, then export the produced animation video, upload the animation video through the relevant management platform, and share and display the rooftop photovoltaic power station project through the relevant design platform.

[0023] Among them, when making the animation, the opening of the animation adopts a growth animation. Subsequently, the bird's-eye view circles around the rooftop photovoltaic power station once, and then the details of the photovoltaic panels are translated and shown from the close-up view. Finally, the scene of the rooftop photovoltaic power station in rainy and snowy weather is restored. By showing the effect after the pre-construction of the rooftop photovoltaic power station through animation production, the scheme display can be made more intuitive, and the communication efficiency of the photovoltaic power station project can be further improved.

[0024] In this embodiment, in step S4, after selecting the key frames from the FBX format files of the rooftop three-dimensional reconstruction model and the three-dimensional map model, it is necessary to adjust the material parameters and animation parameters of the selected frames. Specifically, for the adjustment of the material parameters, the focus is on adjusting the glossiness and material texture maps of the photovoltaic panels and components, etc., so that the overall effect is closer to the real effect display; for the adjustment of the animation effect parameters, it focuses on aspects such as lighting, sky / weather, etc. The solar height and brightness, sky state, cloud speed, position, height, and precipitation, etc. can be adjusted to simulate the real effect of the rooftop photovoltaic power station in different weather environments. By adjusting the material parameters and animation parameters of the selected frames, the overall effect of the animation production can be made closer to the real effect display, thereby improving the completion efficiency of the photovoltaic power station project.

[0025] In this embodiment, in step S4, when uploading the animation video through the management platform, the specific operation is as follows: Open the video management in the management platform and click on the new video storage management; in the new video storage management interface, first fill in the name of the animation video, then upload the animation video to be uploaded, select the video category for the animation video, and finally click confirm to successfully upload the animation video; by uploading the animation video to the management platform, the animation video can be stored and managed for subsequent viewing and display.

[0026] In this embodiment, in step S4, when sharing and displaying the rooftop photovoltaic power station project through the design platform, the specific operation is as follows: Open the sharing management interface in the resource management of the design platform, select the sharing address of the project to be shared, copy the sharing address and share it with relevant personnel; relevant personnel open the sharing address, enter the mobile phone number and the corresponding extraction code, and the sharing interface of the relevant project will be displayed. The sharing interface includes the three-dimensional reconstruction model in the pre-construction stage of the rooftop photovoltaic power station project and the animation video located in the upper right corner of the display interface; by sharing and displaying the designed rooftop photovoltaic power station project, the communication efficiency among project-related personnel can be improved, and the understanding and expectation deviation can be reduced.

[0027] In summary, the present invention uses technical methods such as drone data collection technology, three-dimensional reconstruction means, 3D visualization software, and related management platforms to produce an animation video of the real effect after the pre-construction of the rooftop photovoltaic power station for visual display. It can restore the rooftop photovoltaic power station project and plan in a 1:1 manner, serving as a pre-display of the project effect, making the plan display more intuitive and project communication more efficient. It solves the problems of poor visualization effect and low communication efficiency existing in traditional photovoltaic engineering projects, and has significant progressiveness.

[0028] The above embodiments are only for illustrating the technical idea of the present invention and cannot be used to limit the protection scope of the present invention. Any changes made on the basis of the technical solution according to the technical idea proposed by the present invention fall within the protection scope of the present invention.
