The data processing method of the embodiment of the application can be executed by the determining system of the missed-beat region of the photovoltaic power station of the embodiment of the application, and the determining system of the missed-beat region of the photovoltaic power station of the embodiment of the application can be configured in the server of the embodiment of the application to execute the missed-beat region determining method. The server in the embodiment of the application can be any server capable of interacting with the client of the unmanned aerial vehicle and processing related data, for example, the server can be a server in a ground station of a photovoltaic power station.
The image data of the photovoltaic power station comprises a shot photo image of the photovoltaic power station or collected point cloud data and the like.
In this application embodiment, communication connection is established with unmanned aerial vehicle to the server, and unmanned aerial vehicle's flight control module is patrolled and examined the route after receiving the initial of server generation, patrols and examines the route according to the initial and flies, gathers photovoltaic power plant's image data at the flight in-process. When image data are collected specifically, images of the photovoltaic power station can be shot through camera equipment such as a visible light camera and an infrared camera which are carried on the unmanned aerial vehicle in advance, and point cloud data of the photovoltaic power station can also be collected through a laser radar of the unmanned aerial vehicle. Furthermore, the server receives the image data of the photovoltaic power station uploaded by the unmanned aerial vehicle according to communication connection
It should be further explained that, in an embodiment of the present application, a plurality of types of camera devices can be set on the unmanned aerial vehicle in advance, the photovoltaic power station is shot from different angles through the plurality of camera devices, a plurality of image data are acquired, and the point cloud data of the photovoltaic power station is collected by combining the laser radar. Therefore, the image data of the photovoltaic power station can be acquired in a plurality of modes, and the corresponding image acquisition mode is selected according to actual factors such as weather conditions, so that the method and the device are suitable for image acquisition requirements in different application scenes.
And S102, obtaining a CAD drawing of the photovoltaic power station.
The CAD electronic drawing paper can be a CAD electronic drawing paper which is designed by designers of the photovoltaic power station and used for construction, the CAD electronic drawing paper can be files in multiple formats such as DWG (drawing weight generation), and the CAD electronic drawing paper comprises various devices in the photovoltaic power station, for example, various photovoltaic group strings installed in the photovoltaic power station. It should be noted that the photovoltaic string included in the CAD electronic drawing is a standard string, that is, a string actually existing in the photovoltaic power station.
The photovoltaic group string is a unit which is formed by connecting a plurality of photovoltaic components in series and has a voltage output function, and comprises components, a strip-shaped foundation, a cylindrical foundation, photovoltaic components and a support thereof.
Specifically, the pre-stored CAD drawing of the photovoltaic power station can be directly called from the database of the server.
And S103, comparing the image data of the photovoltaic power station with the CAD drawing of the photovoltaic power station, and determining a missed shot region of the photovoltaic power station.
Specifically, the photovoltaic string can be used as a comparison object, and the photovoltaic power station image is compared with the CAD electronic drawing to generate a missed shot region of the photovoltaic power station. And if the comparison shows that the photovoltaic group strings of the CAD electronic image at a certain specific position are absent in the image data of the photovoltaic power station acquired by the unmanned aerial vehicle, determining that the missed shot region exists in the photovoltaic power station image acquired according to the initial routing inspection path. And further, determining specific coordinates of a missed shot region in the photovoltaic power station according to the specific position lacking the photovoltaic string.
In order to more clearly illustrate a specific implementation manner of determining a missed shot region of a photovoltaic power station by comparison, an embodiment of the present invention further provides an exemplary description of a method for determining a missed shot region based on comparison, and fig. 2 is a flowchart of a specific method for determining a missed shot region based on comparison of image data of a photovoltaic power station and a CAD drawing, which is provided by the embodiment of the present invention, and as shown in fig. 2, the method includes the following steps:
step S201, determining the group string collected in the current inspection from the image data of the photovoltaic power station.
Specifically, the photovoltaic group string may be determined from the acquired image data of the photovoltaic power station by using an image segmentation technique. The image of the photovoltaic power station is divided into a plurality of non-overlapping sub-regions through image segmentation, so that the features in the same sub-region have certain similarity, and the features of different sub-regions are obviously different. Then, the area where the photovoltaic group string is located is divided, and interference images except the photovoltaic group string in the image of the photovoltaic power station are screened out, for example, background images of the group string and other surrounding equipment are screened out, so that the subsequent comparison with the standard group string in the CAD electronic drawing is more direct. In particular, the segmentation may be performed by a segmentation method such as edge detection.
And S202, analyzing the CAD electronic drawing of the photovoltaic power station to obtain a standard group string in the CAD electronic drawing.
Specifically, the CAD electronic drawing is analyzed, and the standard group string drawn in the drawing is determined according to the drawing rule of the CAD drawing. It should be noted that, because the CAD file is structured electronic data, the standard group string can be directly and quickly obtained from the electronic data by analyzing the CAD file, and compared with an image recognition technology, the standard group string can be more conveniently obtained.
In an embodiment of the present application, parsing a CAD electronic drawing of a photovoltaic power station to obtain a standard string in the CAD electronic drawing includes: converting the CAD drawing of the photovoltaic power station into a file in a DXF format under the condition that the CAD drawing of the photovoltaic power station is in a DWG format; the data for the standard group string is obtained based on the file in the DXF format.
Specifically, if the obtained CAD electronic drawing of the photovoltaic power station is a dwg format file, the dwg format file is converted into a dxf file, and then the dxf file is analyzed. The dxf file is in a CAD data file format used for CAD data exchange between AutoCAD and other software, is in an open-source CAD data file format, and has better readability compared with a proprietary file format dwg, so that the dxf file can be analyzed more quickly to obtain data inside the file.
And step S203, comparing the group strings acquired by the current inspection with the standard group strings in the CAD electronic drawing to generate a missed shot region of the photovoltaic power station.
Specifically, the group strings acquired by the current patrol, which are determined by image segmentation, are compared with the standard group strings in the CAD electronic drawing, and if one or more of the standard group strings in the CAD electronic drawing are absent in the group strings acquired by the current patrol, a missed shot region is determined. And then, determining specific coordinates of the missed shot region in the photovoltaic power station according to the position coordinates of the missing photovoltaic group strings, wherein the position coordinates of the missing photovoltaic group strings can be determined according to the information in the CAD drawing because the data information of the standard group strings in the CAD electronic drawing is determined.
For example, if photovoltaic string strings of the CAD electronic image at a specific position is absent, the coordinate of the photovoltaic string is taken as the center coordinate of the missed shot region, the corresponding range is taken as the missed shot region by taking the center coordinate as the center, and if photovoltaic string strings of the CAD electronic image at a plurality of specific positions is absent, the missed shot region is determined by integrating the coordinates of the plurality of photovoltaic string, and the missed shot region is determined to cover the plurality of absent photovoltaic string.
It should be noted that, in an embodiment of the present application, other files including the standard string may also be obtained and compared with the acquired image data of the photovoltaic power station, for example, an acceptance file generated by the photovoltaic power station in a system acceptance link is obtained, a photovoltaic string actually installed and recorded in the acceptance file is obtained, and then compared with the string acquired by the current inspection. As described above, since the CAD file can obtain the standard string from the electronic data more directly and quickly than other types of files, the CAD drawing of the photovoltaic power station is preferably used for comparison in the embodiment of the present application, however, in practical applications, the corresponding file including the standard string may be selected according to practical conditions for comparison, so as to ensure the performability and applicability of the determination method for the missed shot region of the photovoltaic power station in the present application.
And step S104, updating the initial routing inspection path according to the missed-beat region of the photovoltaic power station.
Specifically, the initial routing inspection path is updated according to the missed-shot region of the photovoltaic power station, namely, a new routing inspection path is generated according to the missed-shot region, and the newly generated routing inspection path is ensured to cover the position of the missed-shot photovoltaic string. And then, the unmanned aerial vehicle can be controlled to patrol the photovoltaic power station again according to the new patrol path.
In order to more clearly illustrate a specific implementation manner of updating the initial routing inspection path according to the missed-shot region of the photovoltaic power station, a specific updating method of the initial routing inspection path is further provided in an embodiment of the present application for exemplary illustration, and fig. 3 is a flowchart of the specific updating method of the initial routing inspection path provided in the embodiment of the present application, and as shown in fig. 3, the method includes the following steps:
and S301, performing filling processing on the string graph in the photovoltaic power station model according to the missed string in the missed shot region.
The photovoltaic power station model can be a digital model which is established in the server and used for carrying out operation and maintenance processing such as routing inspection on the photovoltaic power station, actual information of the photovoltaic power station can be represented through the photovoltaic power station model, for example, a group string in the photovoltaic power station model represents a group string actually installed in the photovoltaic power station, and relevant parameter generation instructions in the photovoltaic power station model can be used for carrying out processing such as routing inspection on the photovoltaic power station.
Specifically, through comparison, if the string at the specific position of the CAD electronic drawing is determined not to appear in the photovoltaic image, the area where the string at the specific position is determined to be a missed shot area, and the string graph in the photovoltaic power station model is supplemented according to the string in the missed shot area, wherein the photovoltaic string is supplemented at the corresponding position in the string graph according to the position of the missed shot string, so that the string graph corresponds to the actual standard string.
And step S302, regenerating the routing inspection path of the photovoltaic power station according to the supplemented string diagram.
Specifically, the routing inspection path of the photovoltaic power station is re-planned according to the supplemented string diagram, and the fact that the new routing inspection path of the photovoltaic power station covers the area where all photovoltaic strings are located is guaranteed.
Because this application is mended to the group cluster picture in the power station model, then according to the group cluster picture regeneration photovoltaic power station of mending after the whole route of patrolling and examining, unmanned aerial vehicle patrols and examines the route according to the photovoltaic power station of mending after the whole and gathers the image again and can not take place to leak and clap, has consequently realized that photovoltaic power station patrols and examines the effect of not omitting comprehensively.
In order to further improve the rationality that the route was formulated patrolled and examined, reduce the invalid flight of unmanned aerial vehicle, in this application embodiment, after the route is patrolled and examined to the beginning according to photovoltaic power plant's missed measure district and is updated, still include: and determining an invalid shooting area and an inefficient shooting area according to the image data of the photovoltaic power station, and adjusting the updated initial routing inspection path according to the invalid shooting area and the inefficient shooting area.
Specifically, each piece of image data acquired by the unmanned aerial vehicle is sequentially analyzed, an image in which a photovoltaic group string is not shot, only partial components in the photovoltaic group string are shot, and only a small number of images of the photovoltaic group string are shot in all images of the photovoltaic power station are determined, and an invalid shooting area and an inefficient shooting area in an initial routing inspection path are determined according to the images. Furthermore, after the initial routing inspection path is updated according to the missed shooting area of the photovoltaic power station, the newly generated routing inspection path can be adjusted according to the invalid shooting area and the inefficient shooting area, invalid flight of the unmanned aerial vehicle is reduced, and the unmanned aerial vehicle can shoot more complete and richer images under the condition of flying a shorter distance. Thereby reduce the cost that unmanned aerial vehicle patrolled and examined, improve validity and the economic nature of unmanned aerial vehicle flight.
It should be noted that, because this application is after going on updating the initial route of patrolling and examining according to the missed measure district of photovoltaic power plant, again according to invalid shooting region and the regional regulation of low efficiency shooting, avoid adjusting the region of group cluster of shooing of failing of confirming in the adjustment process to on the basis of guaranteeing that the route of patrolling and examining of photovoltaic power plant after the completion reacquires the image and can not take place to miss the shoot, the rethread adjustment improves the validity that unmanned aerial vehicle flies.
To sum up, according to the intelligent surveying method for the photovoltaic power station infrastructure progress, the point cloud image of the photovoltaic power station is obtained through the laser radar of the unmanned aerial vehicle, the point cloud image of the photovoltaic string is screened out from the point cloud image of the photovoltaic power station, the CAD drawing of the photovoltaic power station is obtained, and finally the infrastructure progress of the photovoltaic power station is generated based on the point cloud image of the photovoltaic string and the CAD drawing of the photovoltaic power station. Therefore, according to the method, construction progress surveying is conducted by comparing construction drawings without walking to the real ground by a constructor, and the infrastructure progress of the photovoltaic power station can be obtained only by controlling the unmanned aerial vehicle to fly above the photovoltaic power station under construction to collect point cloud images and then comparing the point cloud images with the CAD drawings, so that convenience and intelligence of the photovoltaic power station infrastructure surveying are improved, labor cost is reduced, and efficiency of the photovoltaic power station infrastructure surveying is improved.
