Description

Technical Field

[0001] This invention belongs to the field of photovoltaic power generation technology, and relates to a method and related device for identifying and calculating the installation of column foundations for photovoltaic power plants. Background Technology

[0002] Photovoltaic power plants are typically built in open-air environments, facing the elements such as wind, rain, and snow. As a crucial structure supporting the photovoltaic (PV) brackets and modules, the accuracy of the column foundation's installation and identification directly impacts the overall structural safety of the PV power plant. If the column foundation's installation position is off, or if the installation quality is substandard, the stability of the PV brackets and modules may be affected, consequently impacting the safe operation of the entire PV power plant. The power generation efficiency of a PV power plant is closely related to the light-receiving area and angle of the PV modules. If the column foundation's installation position is off, the light-receiving area of ​​the PV modules may decrease, or the angle may deviate from the optimal value, thus reducing the power generation efficiency of the PV power plant. Therefore, accurate column foundation installation identification ensures that the PV modules receive sunlight at the optimal angle and position, thereby improving the power generation efficiency of the PV power plant.

[0003] However, in current practice, the crucial step of identifying the column foundations for photovoltaic power plants largely relies on manual measurement. While manual measurement offers some flexibility, its accuracy is often difficult to guarantee. Specifically, manual measurement can be affected by various factors, such as the skill level of the measurement personnel, the precision of the measuring tools, and environmental conditions. These factors can all lead to deviations in the measurement results, thus affecting the accuracy of the photovoltaic power plant's column foundation installation. Summary of the Invention

[0004] The purpose of this invention is to provide a method and related device for identifying and calculating the installation progress and location of column foundations in photovoltaic power plants, so as to solve the technical problem that the existing technology mostly uses manual measurement to identify the installation progress and location of column foundations, which is prone to deviation and inaccurate measurement.

[0005] To achieve the above objectives, the present invention employs the following technical solution:

[0006] In a first aspect, the present invention provides a method for identifying and calculating the installation of column foundations for photovoltaic power plants, comprising the following steps:

[0007] Acquire image data of photovoltaic power plants;

[0008] The image data is overlaid and segmented to detect columnar bases in the image;

[0009] Calculate the geographic coordinates of the cylindrical bases in the image;

[0010] Based on the geographical coordinates of the column foundations, the column foundations in the image are matched with those in the design drawings, and the installation status of the column foundations is statistically analyzed.

[0011] Furthermore, in the step of acquiring image data of the photovoltaic power station, the image data is all orthophoto data. The data source is satellite imagery, aerial imagery, or UAV imagery.

[0012] Furthermore, the step of overlapping and segmenting the image data to detect columnar bases in the image specifically includes:

[0013] Overlapping and cropping the image data of photovoltaic power stations yields several sets of smaller images;

[0014] Traverse all small images, detect the bounding boxes of the column bases on the small images, and then perform deduplication and image fusion on the detected column bases to obtain the complete image of the column bases.

[0015] Furthermore, the step of calculating the geographic coordinates of the cylindrical base in the image specifically includes:

[0016] The image data of the cylindrical base image is matched with the actual geographical location to establish a mapping relationship between the image coordinate system and the geographic coordinate system;

[0017] Based on the mapping relationship and the position information of the column foundation in the image, the precise position of the column foundation in the geographic coordinate system is calculated.

[0018] Furthermore, the design drawings are in the following formats: dwg, stl, stp, ipt, prt, iges, or obj.

[0019] Furthermore, the column foundation installation details include: column foundation installation location, column foundation installation progress, and column foundation installation deviation.

[0020] Furthermore, the formula for calculating the installation deviation of the column foundation is as follows:

[0021] Δx=x1–x2

[0022] Δy=y1–y2

[0023]

[0024] In the formula, Δx is the deviation of the column foundation centerline in the x-axis direction; x1 is the actual position of the column foundation in the x-axis direction; x2 is the designed position of the column foundation in the x-axis direction; Δy is the deviation of the column foundation centerline in the y-axis direction; y1 is the actual position of the column foundation centerline in the y-axis direction; y2 is the designed position of the column foundation centerline in the y-axis direction; and ΔD is the overall positional deviation of the column centerline.

[0025] Secondly, the present invention provides a photovoltaic power station column foundation installation identification and calculation system, comprising:

[0026] The data acquisition module is used to acquire image data from the photovoltaic power station;

[0027] The image detection module is used to perform overlapping and segmentation on the image data to detect columnar bases in the image;

[0028] The coordinate calculation module is used to calculate the geographic coordinates of the cylindrical bases in the image;

[0029] The matching and statistics module matches the column foundations in the image with the column foundations in the design drawings based on the geographical coordinates of the column foundations, and counts the installation status of the column foundations.

[0030] Thirdly, the present invention provides a computer device including a memory, a processor, and a computer program stored in the memory and executable on the processor, wherein the processor executes the computer program to implement the steps of the method described above.

[0031] Fourthly, the present invention provides a computer-readable storage medium storing a computer program that, when executed by a processor, implements the steps of the method described above.

[0032] Compared with the prior art, the present invention has the following beneficial effects:

[0033] This invention discloses a method and related device for identifying and calculating column foundations in photovoltaic power plants. By acquiring image data of the photovoltaic power plant and overlapping and segmenting it, the method can more accurately detect column foundations in the image. By traversing all smaller images, detecting the bounding boxes (bboxes) of the column foundations on the smaller images, and performing deduplication and image fusion, a more complete and accurate image of the column foundations can be obtained. This step significantly improves the recognition accuracy of column foundations, and the automated processing also improves work efficiency. The core innovation of this method is to match the image data of the column foundations with the actual geographical location and establish a mapping relationship between the image coordinate system and the geographic coordinate system. This step allows us to accurately calculate the position of the column foundation in the geographic coordinate system based on its location in the image. This is of great significance for the operation and maintenance management, fault diagnosis, and subsequent expansion of photovoltaic power plants. Compared with traditional manual measurement methods, this method achieves automated identification and calculation, greatly reducing manual intervention. This not only improves work efficiency but also reduces errors and costs caused by human factors. At the same time, this method also reduces the reliance on professional surveyors, making the construction and operation and maintenance of photovoltaic power plants more convenient and economical. Accurate identification of column foundation installations is crucial for the safety and stability of photovoltaic power plants. This method, by precisely calculating the position of the column foundation in the geographic coordinate system, can promptly identify and resolve issues such as installation deviations. This helps ensure the structural safety of photovoltaic power plants and improves their power generation efficiency and operational stability. Attached Figure Description

[0040] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0041] Therefore, the following detailed description of the embodiments of the invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the invention without inventive effort are within the scope of protection of the invention.

[0042] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0043] In the description of the embodiments of the present invention, it should be noted that if terms such as "upper," "lower," "horizontal," or "inner" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product of the invention is in use, they are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention. Furthermore, terms such as "first" and "second" are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0044] Furthermore, the use of the term "horizontal" does not imply that the component must be absolutely horizontal, but rather that it can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal than "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0045] In the description of the embodiments of the present invention, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in the present invention according to the specific circumstances.

[0046] The present invention will now be described in further detail with reference to the accompanying drawings:

[0047] See Figure 1 This invention discloses a method for identifying and calculating the installation of column foundations in photovoltaic power plants, comprising the following steps:

[0048] Step 1: Acquire image data of the photovoltaic power station;

[0049] In this step, all image data are orthophotos; the data sources are satellite imagery, aerial imagery, or UAV imagery. This step is fundamental to the entire recognition and calculation method. First, professional image acquisition equipment (such as high-definition cameras, high-resolution cameras mounted on UAVs, etc.) is used to capture images of the photovoltaic power station from all angles. This ensures that the acquired image data is clear and complete, fully covering all areas of the photovoltaic power station, especially the area where the column foundations are located. Simultaneously, considering the potential impact of factors such as lighting conditions and weather on image quality, image acquisition must be conducted at appropriate times to ensure the accuracy of subsequent processing.

[0050] Step 2, see Figure 3 The image data is overlapped and segmented to detect columnar bases in the image;

[0051] Step 201: Overlap and cut the image data of the photovoltaic power station to obtain several sets of small images;

[0052] Step 202: Traverse all small images, detect the bounding boxes of the column bases on the small images, and then perform deduplication and image fusion on the detected column bases to obtain the complete column base image;

[0053] After acquiring the image data of the photovoltaic power station, the next step is to perform overlapping and segmentation processing on these images. The purpose of overlapping and segmentation is to divide the large area of ​​image data into multiple smaller blocks to facilitate subsequent cylindrical foundation detection. Simultaneously, overlapping and segmentation can also improve the accuracy and robustness of the detection to a certain extent, because even if a portion of the image fails to detect the cylindrical foundation due to factors such as lighting or occlusion, it can be supplemented and corrected by the overlapping portion of adjacent images. During the overlapping and segmentation process, it is necessary to set the segmentation parameters appropriately, such as the size of the segmented blocks and the degree of overlap, to ensure that the segmented image blocks meet the detection requirements without causing excessive computational burden.

[0054] Step 3: Calculate the geographic coordinates of the cylindrical base in the image;

[0055] Step 301: Match the image data of the cylindrical base image with the actual geographical location to establish a mapping relationship between the image coordinate system and the geographic coordinate system;

[0056] Step 302: Calculate the precise location of the column base in the geographic coordinate system based on the mapping relationship and the position information of the column base in the image.

[0057] It's important to note that this step typically relies on advanced computer vision algorithms and deep learning techniques. A well-trained model can automatically identify cylindrical bases in an image and extract corresponding feature information, such as shape, size, and location. To improve detection accuracy, multiple algorithms and techniques can be combined for fusion processing, such as edge detection, shape matching, and color analysis. Simultaneously, the detection results need to be validated and filtered to eliminate false positives and false negatives.

[0058] Step 4, see Figure 4 Based on the geographical coordinates of the column foundations, the column foundations in the image are matched with those in the design drawings, and the installation status of the column foundations is statistically analyzed.

[0059] In this step, the design drawings are in DWG, STL, STP, IPT, PRT, IGES, or OBJ format. The column foundation installation details include: column foundation installation location, column foundation installation progress, and column foundation installation deviation. The formula for calculating the column foundation installation deviation is:

[0060] Δx=x1–x2

[0061] Δy=y1–y2

[0062]

[0063] In the formula, Δx is the deviation of the column foundation centerline in the x-axis direction; x1 is the actual position of the column foundation in the x-axis direction; x2 is the designed position of the column foundation in the x-axis direction; Δy is the deviation of the column foundation centerline in the y-axis direction; y1 is the actual position of the column foundation centerline in the y-axis direction; y2 is the designed position of the column foundation centerline in the y-axis direction; and ΔD is the overall positional deviation of the column centerline.

[0064] See Figure 2 This invention discloses a photovoltaic power station column foundation installation identification and calculation system, including a data acquisition module, an image detection module, a coordinate calculation module, and a matching statistics module.

[0065] It should be noted that the data acquisition module is used to acquire image data of the photovoltaic power station; the image detection module is used to overlap and cut the image data to detect the column foundations in the image; the coordinate calculation module is used to calculate the geographical coordinates of the column foundations in the image; and the matching and statistics module matches the column foundations in the image with the column foundations in the design drawings based on the geographical coordinates of the column foundations to count the installation status of the column foundations.
