[0050] It should be noted that the logic and / or steps represented in the flowchart or described in other ways herein, for example, can be considered as a sequenced list of executable instructions for implementing logical functions, and can be specifically implemented in any computer-readable medium for use by an instruction execution system, device or equipment (such as a computer-based system, a system including a processor, or other system that can fetch instructions from an instruction execution system, device or equipment and execute instructions), or used in combination with these instruction execution systems, devices or equipment.

[0051] The flow chart provided by the present embodiment is not intended to indicate that the operation of the method will be performed in any particular order, or that all operations of the method are included in all every case. In addition, the method may include additional operations. Within the scope of the technical thinking provided by the present embodiment method, additional changes may be made to the above method.

[0052] like Figure 1 As shown, in one embodiment, the design method of a photovoltaic power station generally includes:

[0053] Step S101, obtaining address information of the photovoltaic power station installation area. Specifically, the address information is information used to determine the geographical location of the installation area, such as geographical coordinate information (latitude and longitude) or administrative area address (administrative division, road house number) of the installation area.

[0054] Step S102, check whether the pre-associated third-party software has a 3D model of the installation area. If so, execute step S103, if not, execute step S104. Specifically, in the prior art, some open source map software has pre-built 3D models of some areas for users to directly retrieve or can share 3D models built by other users, such as Sencheng City Software, AutoNavi Map Open Platform, etc. Therefore, by pre-associating with a third-party software, after obtaining the address information of the installation area, check whether the corresponding 3D model can be directly obtained from the pre-associated third-party software.

[0055] Step S103, obtaining a three-dimensional model. If the pre-associated third-party software already has a three-dimensional model of the installation area, the three-dimensional model can be directly obtained.

[0056] Step S104: Control the drone to take aerial photos of the installation area to obtain a survey image.

[0057] Step S105: generating a three-dimensional model according to the survey image.

[0058] If the pre-associated third-party software does not have a 3D model of the installed area, the 3D model is built by itself using drone aerial images.

[0059] Reference Figure 2 As shown, in one embodiment, the survey image includes a first aerial image, and step S104 includes:

[0060] Step S201, generating an aerial photography area covering the installation area on the plane map according to the address information. Specifically, the aerial photography area covering the installation area is displayed on the plane map. For example, if the photovoltaic power station needs to be built on the roof of a building, the aerial photography area is a graphic covering the building on the plane map.

[0061] It should be noted that the aerial photography area may be generated by receiving the frame selection information of the user, or may be automatically generated according to the range of the installation area on the plane map.

[0062] Step S202, generating a first aerial photography plan according to the aerial photography area. Specifically, the aerial photography plan includes flight parameters and shooting parameters of the drone, such as flight route, flight speed, shooting interval, shooting angle, and other parameters. The flight route of the first aerial photography plan has route portions located inside and outside the aerial photography area, and at each shooting point located outside the installation area, at least three images of the upper, middle, and lower angles are shot in the direction in which the lens faces the installation area.

[0063] Specifically, the flight route is generally a tortuous route generated based on the aerial photography area, such as Figure 3 As shown in , the quadrilateral area is a schematic diagram of the aerial photography area, and the lines are schematic diagrams of the aerial photography route. Because it is generated according to the aerial photography area, the first aerial photography plan is to shoot above the installation area. If it is a building roof, the aerial photography is performed above the building roof. In addition, during the drone aerial photography process, at each shooting point outside the installation area, that is, in terms of plane, the drone shooting point is outside the plane graphic range of the installation area, at least three photos are taken in the direction of the lens facing the installation area, one camera is tilted upward to shoot, one camera is shot horizontally, and one camera is tilted downward to shoot.

[0064] Step S203, control the drone to perform aerial photography according to the first aerial photography scheme to obtain a first aerial image. After the first aerial photography scheme is generated, the drone can be controlled to perform photography according to the first aerial photography scheme to obtain a plurality of first aerial images.

[0065] Specifically, by configuring the first aerial photography scheme to capture images at at least three angles, namely, upper, middle and lower, at each shooting point outside the installation area in the direction in which the lens is facing the installation area, the installation area observed from the top and the environmental conditions in the longitudinal direction around the building can be obtained based on the first aerial image, thereby facilitating better generation of a three-dimensional model of the installation area using survey images.

[0066] Continue to refer to Figure 2 As shown, further, the survey image also includes a second aerial image, and step S104 further includes:

[0067] Step S204, generating a second aerial photography plan based on the first aerial image, wherein the flight route of the second aerial photography plan surrounds the installation area, and the flight altitude is lower than the flight altitude of the first aerial photography plan, and at each shooting point, at least three angles of images are shot in the direction of the lens toward the installation area, and three angles of images are shot in the direction of the lens away from the installation area.

[0068] The second aerial photography route surrounds the installation area and is lower than the flight altitude of the first aerial photography solution. If the installation area is a building roof, the flight route of the second aerial photography solution flies around the building and the flight altitude is lower than the roof. In addition, at each shooting point, at least three angles of images are taken in the direction of the lens facing the installation area, and three angles of images are taken in the direction of the lens facing away from the installation area. In this way, it can be more clearly determined whether there are objects around the installation area that are higher than the building, so as to better perform subsequent shadow analysis.

[0069] Because the second aerial photography plan revolves around the installation area, after understanding the general situation of the installation area and the surrounding environment based on the first aerial photography image, it can be determined whether there are obstacles such as special-shaped protruding structures around the building that hinder flight, thereby better determining the route of the second aerial photography plan.

[0070] Step S205: Control the drone to perform aerial photography according to the second aerial photography scheme to obtain a second aerial image. The first aerial image and the second aerial image are used as survey images.

[0071] like Figure 4 As shown, step S105 may include:

[0072] Step S301, discretize the survey image using set grid points to generate point cloud data of the installation area. One discretization method is: discretize using three-dimensional space grid points, and then sample a point in each grid point. Each small grid contains several points, and the point closest to the center point of the grid is taken as the discrete sampling point.

[0073] Step S302, using the point cloud data to construct a surface to obtain a surface model; the data captured by the drone can be processed to obtain sufficient point cloud data. Through surface construction, a surface model in the form of a point cloud can be obtained.

[0074] Step S303, perform object recognition on the survey image to determine the object boundary. The object recognition results include: installation objects (installation roofs, installation walls, vacant ground, etc.), basic objects of installation objects (installed building objects, walls, supports, etc.), surrounding environment objects, etc.

[0075] Step S304: compare the object boundary with the surface model and perform contour segmentation on the surface model.

[0076] Step S305, visualize the surface model after contour segmentation to obtain a three-dimensional model. The specific visualization process may include: performing object entity processing on the surface model after contour segmentation to obtain contour surfaces of multiple objects; collecting color and pattern features of multiple objects in the survey image; performing appearance processing on the contour surfaces of multiple objects according to the color and pattern features to obtain a three-dimensional model of the installation area.

[0077] The final three-dimensional model of the installation area is similar to the actual visual state of the installation area, which is convenient for the construction owner of the photovoltaic system to intuitively understand the situation of the installation area. After obtaining the three-dimensional model of the installation area, it also includes: performing data statistics on the three-dimensional model to obtain data information of the three-dimensional model; assigning attribute information to multiple objects of the three-dimensional model. The data information of the three-dimensional model includes: coordinates, elevation data, area, length, height, slope, direction, etc., which can be read from the three-dimensional model. Object attribute information includes: project name, object type, etc.

[0078] Step S106, designing a photovoltaic power station in the three-dimensional model. After the three-dimensional model is directly acquired or generated, the photovoltaic power station is designed in the three-dimensional model to obtain a three-dimensional layout plan of the photovoltaic power station.

[0079] In the solution of this embodiment, after obtaining the address information of the photovoltaic power station installation area, first check whether the pre-associated third-party software already has a three-dimensional model of the installation area. If the pre-associated third-party software already has a three-dimensional model of the installation area, directly obtain the three-dimensional model, thereby effectively reducing the construction work of the three-dimensional model and helping to improve the design efficiency of the photovoltaic power station. If the pre-associated third-party software does not have a three-dimensional model of the installation area, control the drone to take aerial photos of the installation area to obtain a survey image, and generate a three-dimensional model based on the survey image, which can also improve the design efficiency of the photovoltaic power station to a certain extent.

[0080] In addition, by generating a first aerial photography plan based on the aerial photography area, the first aerial photography plan includes taking images of the upper, middle and lower angles at least in the direction of the lens toward the installation area at each shooting point outside the installation area, controlling the drone to perform aerial photography according to the first aerial photography plan, and after obtaining the first aerial image, generating a second aerial photography plan according to the first aerial image, the drone flight route of the second aerial photography plan surrounds the installation area, and the flight altitude is lower than the flight altitude of the first aerial photography plan, and at each shooting point, at least takes images of the upper, middle and lower angles in the direction of the lens toward the installation area and takes images of the upper, middle and lower angles in the direction of the lens back to the installation area, controlling the drone to perform aerial photography according to the second aerial photography plan to obtain the second aerial image, and generating a three-dimensional model according to the first aerial image and the second aerial image, the first aerial image can be used to understand the installation area observed from the top and the longitudinal environment around the building, and the second aerial image can be used to more clearly judge whether there are objects around the installation area that are higher than the building, thereby helping to better generate a three-dimensional model of the installation area using survey images. Because the second aerial photography plan revolves around the installation area, after understanding the general situation of the installation area and the surrounding environment based on the first aerial photography image, it can be determined whether there are obstacles such as special-shaped protruding structures around the building that hinder flight, thereby better determining the route of the second aerial photography plan.

[0081] like Figure 5 As shown, in one embodiment, the step of obtaining the address information of the photovoltaic power station installation area includes: obtaining the preset type of the photovoltaic power station installation area; selecting a project template of the corresponding type from a preset template library according to the preset type, the preset template library stores multiple types of project templates, and the project template includes installation area data to be filled and photovoltaic equipment data to be selected; after obtaining the three-dimensional model, the installation area data in the project template is filled according to the three-dimensional model; the step of designing a photovoltaic power station in the three-dimensional model includes: obtaining the selected photovoltaic equipment data; and designing the layout of the photovoltaic power station in the three-dimensional model according to the selected photovoltaic equipment data.

[0082] Reference Figure 5As shown, in this embodiment, the design method of the photovoltaic power station generally includes:

[0083] Step S401, obtaining a preset type of the photovoltaic power station installation area. Specifically, the photovoltaic power station installation area may include a factory building, ground, roof, single-family roof and other types.

[0084] Step S402: selecting a project template of a corresponding type from a preset template library according to a preset type. The preset template library stores multiple types of project templates. The project template includes installation area data to be filled and photovoltaic equipment data to be selected.

[0085] Specifically, the installation area data of each type of project template is set according to the construction scenario of this type, wherein different types of project templates may have the same type of installation area data, such as geographical location, power generation demand, construction area, and climate conditions, etc. At the same time, different types of project templates also have installation area data specific to this type, such as the roof slope of the factory type, the roof type (tile type or steel sheet type) of the single-family type, and so on.

[0086] In addition, photovoltaic equipment data of different types of project templates include a variety of photovoltaic equipment data, such as photovoltaic panel type, photovoltaic panel power generation, photovoltaic panel installation method, inverter type, junction box type, etc., wherein each type of photovoltaic equipment data includes multiple parameters to be selected, such as photovoltaic panel types include monocrystalline silicon and polycrystalline silicon, photovoltaic panel installation methods include following the slope or using a mounting bracket, and when using a mounting bracket, it also includes a variety of data of the mounting bracket, and each data includes multiple parameters to be selected, such as the mounting bracket material: steel or aluminum alloy, etc., assembly method: fixed or tracking, etc.

[0087] It should be noted that the photovoltaic equipment data of different types of project templates can be different. For example, the rooftop type installation method can only have one option of mounting brackets, while the single-family type can have two options: following the slope and mounting brackets. Or, the various parameters to be selected for the photovoltaic panel power generation of the factory type are higher than those of the single-family type. Of course, the photovoltaic equipment data of different types of project templates can also be the same, but some parameters of some types will not be selected.

[0088] Step S403, obtaining address information of the photovoltaic power station installation area. Specifically, the address information is also one of the data of the project template, and is filled into the project template after being obtained.

[0089] Step S404, checking whether the pre-associated third-party software already has a three-dimensional model of the installation area, if so, executing step S405, if not, executing step S406.

[0090] Step S405, obtaining a three-dimensional model.

[0091] Step S406: Control the drone to take aerial photos of the installation area to obtain a survey image.

[0092] Step S407: Generate a three-dimensional model based on the survey image.

[0093] Step S408, fill the installation area data in the project template according to the three-dimensional model. Specifically, fill the data that needs to be measured in the installation area data, such as the construction area or slope, etc., and some installation area data such as geographical location, power generation requirements, etc. can be filled by receiving user input information after the project is generated.

[0094] Step S409, obtaining the selected photovoltaic equipment data. After the installation area data is determined, the selected parameters in each photovoltaic equipment data of the project template are obtained. The system may automatically select according to the selection history of the same type of templates, for example, selecting the photovoltaic equipment data with the highest selection rate in the same type of project templates, or it may receive the user's selection signal for determination.

[0095] Step S410, designing the layout of the photovoltaic power station in the three-dimensional model according to the selected photovoltaic equipment data. After the installation area data and the photovoltaic equipment data are determined, the layout of the photovoltaic power station can be designed in the three-dimensional model.

[0096] In the scheme of this embodiment, by obtaining the preset type of the photovoltaic power station installation area, selecting the corresponding type of project template from the preset template library according to the preset type, the project template includes the installation area data to be filled and the photovoltaic equipment data to be selected, obtaining the three-dimensional model of the installation area, filling the installation area data in the project template according to the three-dimensional model, obtaining the selected photovoltaic equipment data, and designing the layout of the photovoltaic power station in the three-dimensional model according to the selected photovoltaic equipment data. In this way, the user only needs to enter the preset type of the installation area, and the system can use the project template to automatically generate a project with all the required data, and then automatically fill in the data according to the data displayed in the project, reducing the workload of the subsequent user to manually extract the required data, helping to improve the efficiency of photovoltaic power station design, and realizing an efficient and accurate design process, making the construction planning of photovoltaic power stations more convenient and scientific.

[0097] In particular, for designers with less experience, it helps save time for exploration and adjustment in the early stages of design, allowing designers to focus more on higher-level strategic planning and innovation, while the complexity and accuracy of the design itself are automatically guaranteed by the system, achieving efficient and high-quality design goals and providing strong support for the rapid deployment and optimized operation of photovoltaic power stations.

[0098] It should be noted that, in some other embodiments, after completing the design of the project template and generating a project file that meets the preset target requirements, the project file includes a three-dimensional layout model of the photovoltaic power station and related installation area data and photovoltaic equipment data, which can be in the form of a compressed package file, storing the final project file and the vector composed of the installation area data therein, and establishing an index relationship between the vector and the project file.

[0099] In this way, the step of obtaining the selected photovoltaic equipment data may include searching for the most similar historical project template in the same type of historical project template using the vector formed by the filled installation area data. After the installation area data are determined, the vector formed by the installation area data can be used to search for the most similar historical project template of the same type. Then, the photovoltaic equipment data of the most similar historical project template is read, and the same photovoltaic equipment data in the current project template is selected.

[0100] By vectorizing the data, other data similar to one data can be well found. Therefore, this embodiment uses the vector composed of the filled installation area data to find the most similar historical project template in the same type of historical project template, reads the photovoltaic equipment data of the most similar historical project template, selects the same photovoltaic equipment data in the current project template, and can find the historical project template that is most similar to the design target of the project template currently being designed from the historical project template. Then, the photovoltaic equipment data of the project template currently being designed and the most similar historical project template are substantially the same, so by selecting the same photovoltaic equipment data in the current project template as the most similar historical project template, a relatively accurate preliminary photovoltaic equipment data set can be quickly obtained, which helps to further improve design efficiency.

[0101] like Figure 6 As shown, in one embodiment, the steps of designing a photovoltaic power station in a three-dimensional model include:

[0102] Step S501, designing the layout of photovoltaic panels in the three-dimensional model to obtain a preliminary layout plan. Specifically, designing the layout of photovoltaic panels according to relevant data of the photovoltaic panels, such as area, inclination, etc.

[0103] Step S502, preliminary indicators verification is performed on the preliminary layout plan, and the preliminary indicators verification includes shadow analysis and power generation verification. Specifically, after the preliminary layout plan is completed, the laying conditions and specification parameters of the photovoltaic panels have been determined, so shadow analysis and corresponding power generation verification can be easily performed.

[0104] Step S503, determine whether the preliminary index verification meets the preset target requirements, if yes, execute step S504, if not, return to execute step S501, and re-obtain a new preliminary layout plan. That is, determine whether the indicators of the preliminary layout plan meet the various design index requirements of the photovoltaic power station to be built, if not, re-layout the photovoltaic panels.

[0105] Step S504, electrical connection design is performed based on the preliminary layout plan to obtain a plan to be used. If the preliminary indicators of the preliminary layout plan meet the preset target requirements, electrical connection design is performed, that is, the layout and connection of the distribution device and cables are performed.

[0106] In this embodiment, after the photovoltaic panel layout design is performed, a preliminary layout plan is obtained to perform preliminary indicator verification. When the preliminary indicator verification meets the preset target requirements, the electrical connection design is performed on the basis of the preliminary layout plan. If the preliminary indicator verification does not meet the design requirements, the photovoltaic panel layout design is performed again. In other words, the photovoltaic power station is designed in sections. After the first section of the photovoltaic panel layout design, if the preliminary indicator verification does not meet the target requirements, the electrical connection design of the second section will not be performed. Compared with the calculation of various indicators after the photovoltaic power station is fully designed, the sectioned design of this application can timely verify some indicators that can be clearly determined after the photovoltaic panel layout design is completed. If the requirements are not met, the photovoltaic panels only need to be redesigned and laid out, which helps to improve design efficiency and save system operation resources.

[0107] It should be noted that, under the scheme of adopting the project template, the photovoltaic panel layout design is carried out in the three-dimensional model, that is, the photovoltaic panel layout design is carried out according to the data related to the photovoltaic panels in the selected photovoltaic equipment data. If the preliminary indicator verification does not meet the requirements, the data related to the photovoltaic panels in the photovoltaic equipment data is re-selected.

[0108] In addition, when adopting the project template, the preliminary indicator verification can also include preliminary cost verification. Referring to the above, after finding the most similar historical project template, obtain the vector consisting of the first layout information of the preliminary layout plan, take the vector modulus as the first modulus, and the first layout information includes the total area of ​​photovoltaic panels, the inclination angle of photovoltaic panels, and the number of photovoltaic panels of the preliminary layout plan. Obtain the vector consisting of the second layout information of the most similar historical project template, take the vector modulus as the second modulus, and the second layout information includes the total area of ​​photovoltaic panels, the inclination angle of photovoltaic panels, and the number of photovoltaic panels of the most similar historical project template. Determine whether the product of the cost of the most similar historical project template and the ratio of the first modulus to the second modulus meets the preset target cost, that is, whether it is less than or equal to the preset target cost. If so, it is determined that the preliminary cost verification meets the requirements. If not, it is determined that the preliminary cost verification does not meet the requirements.
