Description

Technical Field

[0001] The present invention relates to the field of surveying and mapping technology, and in particular to a system for surveying and mapping environmental and water conservation information of power transmission and transformation lines based on resolution optimization. Background Art

[0002] Transmission and transformation projects are extensive, multi-faceted, and complex, with complex topography at construction sites. Key construction processes include house demolition, tree felling, road construction, land leveling, foundation pit excavation, material transportation, foundation pouring, tower assembly, ground conductor deployment, and commissioning. Construction projects span long distances and a significant timeframe, with numerous surface disturbance points, are prone to environmental and water conservation issues, generating significant public attention. Some construction sites are located in plateaus, mountainous areas, and deserts, characterized by rugged terrain or sparse populations, making transportation difficult. Traditional manual inspections present challenges for environmental and water conservation oversight. Currently, my country only includes environmental assessment and final acceptance in its environmental regulations. The impact of transmission and transformation projects on the ecological environment often begins with project planning and site selection, with significant impacts during the construction phase. By the time a project is finalized and accepted, much ecological damage and environmental pollution has already occurred. This is particularly true for scenic spots, ecological wetlands, and the habitats of rare plants and animals, which are already irreversible. Environmental protection supervision during the construction phase is impacted by factors such as the vast scope of the projects, the complex environment, a small number of supervisors, and a lack of standardized management methods. Furthermore, existing water conservation monitoring is conducted on a quarterly basis. Due to insufficient frequency, problems are often not identified promptly, often remaining undetected until the acceptance stage, hindering acceptance. During and after construction, it is difficult to monitor the impacts of local vegetation damage, soil and rock accumulation, river pollution, and soil erosion. It is also difficult to monitor whether environmental restoration and soil and water conservation measures are being implemented as required, whether demolished housing sites have been restored, and whether new construction is occurring. The need for new monitoring methods to ensure sustained and effective oversight of construction sites has become a pressing issue.

[0003] Traditional environmental protection supervision relies on manual methods such as inspections and field visits, making it difficult to conduct timely, full-line environmental and water conservation monitoring. The recent development of high-resolution remote sensing technology has made it possible to conduct high-frequency, rapid, and cost-effective environmental and water conservation monitoring of the entire power grid, laying a strong foundation for the development of intelligent identification technology for environmental and water conservation targets.

[0004] Therefore, it is necessary to provide a power transmission and transformation line environmental and water conservation information mapping system based on resolution optimization. Summary of the Invention

By using high-resolution satellites in combination with unmanned aerial vehicles (UAVs), remote sensing images of the environmental protection of power transmission and transformation lines are captured to obtain basic information, and ground measurement equipment is used to optimize some content of the basic information. Finally, based on the optimized basic information, the environmental protection information of power transmission and transformation lines is drawn, which can improve the drawing quality of the environmental protection information of power transmission and transformation lines and provide data support for the whole-process control of environmental protection in power transmission and transformation projects.

[0061] The preferred embodiments of the present invention are described below with reference to the drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0062] The present invention provides a water and soil conservation information surveying and mapping system for power transmission and transformation lines optimized based on resolution, as Figure 1 shown, including:

[0063] A basic information acquisition module, configured to use high-resolution satellites in combination with unmanned aerial vehicles to capture remote sensing images of the water and soil conservation of power transmission and transformation lines and obtain basic information;

[0064] An information optimization module, configured to use ground measurement equipment to optimize some contents of the basic information and obtain optimized basic information;

[0065] A surveying and mapping implementation module, configured to draw the water and soil conservation information of the power transmission and transformation lines based on the optimized basic information.

[0066] The working principle of the above technical solution is as follows: To implement a water and soil conservation information mapping system for transmission and transformation lines based on resolution optimization, the present invention proposes a basic information acquisition module. Through the collaborative operation of high-resolution satellites and unmanned aerial vehicles (UAVs), detailed remote sensing images of the environment around the transmission and transformation lines can be captured. These images not only contain the location information of the line itself but also cover important environmental factors such as the terrain, landform, vegetation cover, and water body distribution around the line, providing rich basic data for subsequent water and soil conservation work. An information optimization module is proposed. This module uses ground measurement equipment, such as total stations and GPS positioning systems, to conduct on-site measurement and verification of key parts of the basic information. The advantage of this is that it can make up for the information loss or errors that may be caused by factors such as weather and light in remote sensing images, ensuring the accuracy and integrity of the basic information. A mapping implementation module is proposed. Based on the optimized basic information, advanced mapping technologies and algorithms are used to accurately draw the water and soil conservation information of the transmission and transformation lines. The mapping results not only show the specific route and location of the line but also clearly mark information such as the surrounding environmental protection areas, potential soil erosion risk points, and recommended water and soil conservation measures, providing strong support for relevant departments to formulate scientific and reasonable environmental protection plans.

[0067] The beneficial effects of the above technical solution are as follows: By adopting the solution provided in this embodiment and using the combination of high-resolution satellites and UAVs, the efficiency and accuracy of information acquisition are greatly improved, enabling the mapping work to more comprehensively and meticulously reflect the true situation of the transmission and transformation lines and their surrounding environment. The implementation of the information optimization module effectively reduces the errors that may be caused by the limitations of remote sensing technology itself, enhancing the reliability and practicality of the basic data. The application of the mapping implementation module not only achieves the accurate drawing of water and soil conservation information but also provides scientific and intuitive decision-making basis for relevant departments, contributing to the precise implementation and efficient management of environmental protection work.

[0068] In one embodiment, as Figure 2 shown, the basic information acquisition module includes a first information acquisition unit, a second information acquisition unit, and an information aggregation unit;

[0069] The first information acquisition unit is used to collect remote sensing images of the water and soil conservation of the transmission and transformation lines by using high-resolution satellites to obtain the first information;

[0070] The second information acquisition unit is used to collect information on the area to be confirmed in the first information by using a high-definition camera carried by a UAV to obtain the second information;

[0071] The information aggregation unit is used to aggregate the first information and the second information to obtain the basic information.

[0072] The working principle of the above technical solution is as follows: First, the first information acquisition unit can capture detailed remote sensing images of the power transmission and transformation lines and their surrounding environments through high-resolution satellites. These images contain key information such as the location and orientation of the lines, as well as the surrounding topography, landforms, and vegetation coverage, constituting the first information for a preliminary understanding of the environmental protection situation of the power transmission and transformation lines. Subsequently, the second information acquisition unit uses a high-definition camera carried by a drone to collect more detailed and in-depth information for areas that may be uncertain or require further confirmation in the first information. The high mobility of the drone and the high resolution of the high-definition camera enable this step to accurately capture ground details, such as soil erosion conditions and vegetation growth status in specific areas, thereby generating the second information. Finally, the information aggregation unit integrates the first information and the second information, and through comparison, verification, and supplementation, forms comprehensive, accurate, and detailed basic information.

[0073] The beneficial effects of the above technical solution are as follows: By adopting the solution provided in this embodiment, this workflow not only makes full use of the respective advantages of high-resolution satellites and drones, but also through the integrated processing of the information aggregation unit, ensures the accuracy and integrity of the basic information, providing a solid foundation for subsequent information optimization and mapping implementation.

[0074] In one embodiment, as Figure 3 shown, using a high-resolution satellite, collect remote sensing images of the environmental protection of power transmission and transformation lines to obtain the first information, including:

[0075] Configure a receiving device for accessing the high-resolution satellite and set the working parameters of the receiving device;

[0076] Based on the working parameters, use the receiving device to collect remote sensing images of the environmental protection of power transmission and transformation lines to obtain the first information.

[0077] The working principle of the above technical solution is as follows: With its broad vision and precise imaging ability, the high-resolution satellite can capture the macroscopic scenes of the power transmission and transformation lines and their surrounding environments. When configuring the receiving device, it is necessary to ensure stable communication with the satellite, and the setting of the working parameters needs to be comprehensively considered according to factors such as the satellite's orbit, imaging time, and required image resolution. Once the receiving device is correctly configured and started, it will screen out the remote sensing images related to the environmental protection of the power transmission and transformation lines from the data received from the satellite according to the preset working parameters. After preliminary processing of these image data, the first information containing key information such as the location and orientation of the lines and the surrounding topography can be formed. This process depends not only on the imaging quality of the high-resolution satellite, but also on the precise configuration of the receiving device and the scientific setting of the working parameters to ensure the accuracy and integrity of the first information.

[0078] The beneficial effects of the above technical solution are as follows: By adopting the solution provided in this embodiment, by configuring a receiving device for accessing high-resolution satellites and setting the working parameters of the receiving device, the acquisition of the first information can be effectively and accurately achieved.

[0079] In one embodiment, a high-definition camera is carried by a drone to collect information on the area to be confirmed in the first information, and the second information is obtained, including:

[0080] Carry a high-definition camera on the drone;

[0081] Control the drone and use the high-definition camera to collect information on the area to be confirmed in the first information to obtain the second information.

[0082] The working principle of the above technical solution is as follows: The high-definition camera has the ability of high-resolution imaging and can capture fine ground features when flying at low altitude; through the flexible control of the drone platform, the high-definition camera can accurately collect information on the area to be confirmed marked in the first information; in this process, the drone follows the preset flight path and altitude to ensure that the high-definition camera shoots the area to be confirmed at the best angle and distance, so as to obtain the second information containing richer details; these information not only cover the natural environment features such as the topography and vegetation coverage of the area to be confirmed, but may also contain traces of human activities, such as buildings, roads, etc., providing an important basis for the subsequent environmental protection information mapping around the power transmission and transformation lines.

[0083] The beneficial effects of the above technical solution are as follows: By adopting the solution provided in this embodiment, the information collection by the high-definition camera carried by the drone not only greatly improves the efficiency of data collection, but also significantly enhances the accuracy and comprehensiveness of the data; compared with the traditional manual mapping method, the solution of the high-definition camera carried by the drone can cover a wider area, while reducing the dependence on human and material resources and lowering the mapping cost; in addition, the combined use of the drone and the high-definition camera also makes it possible to conduct mapping in complex or inaccessible terrains, further expanding the application scope of the environmental protection information mapping around the power transmission and transformation lines.

[0084] In one embodiment, control the drone and use the high-definition camera to collect information on the area to be confirmed in the first information to obtain the second information, including: determining the area to be confirmed, specifically:

[0085] Extract several target images from the remote sensing image and obtain the resolutions of the several target images;

[0086] Match and analyze the resolutions of the several target images with the standard resolutions in the set target image standard resolution database to obtain the first target images corresponding to the several resolutions with inconsistent matches;

[0087] Determine the area corresponding to the first target image as the area to be analyzed and confirmed;

[0088] Query the monitoring level of the area to be analyzed and confirmed in the set area monitoring level database. If the monitoring level is greater than the set monitoring level threshold, determine the area to be analyzed and confirmed as the area to be confirmed; where the monitoring level is determined by the monitoring rating of the importance of the power transmission and transformation line environmental protection for the area.

[0089] The working principle of the above technical solution is as follows: In order to determine the area to be confirmed, the present invention uses remote sensing image technology to first screen out target images that may have doubts or need further confirmation; these target images may have insufficient resolution or other factors, resulting in unclear or inaccurate information presentation; in order to improve the efficiency and accuracy of subsequent information mapping, the system will carefully analyze the resolution of these target images; the specific method is to compare the resolution of the target images with the preset standard resolution database to find those target images that deviate from the standard, that is, the first target images. The areas corresponding to these images are likely to be key areas that need further analysis and confirmation; then, the system will conduct a more in-depth exploration of the area to be analyzed and confirmed; using the area monitoring level database, the system can query the monitoring level of each area to be analyzed; the monitoring level is evaluated according to the importance of the power transmission and transformation line environmental protection of the area. The higher the level, the higher the requirements for the accuracy and integrity of the environmental protection information in this area; when the monitoring level of a certain area to be analyzed exceeds the preset monitoring level threshold, this area is officially determined as the area to be confirmed and becomes the focus of subsequent UAV information collection; the design of this work process aims to ensure that the information collection is more targeted, and at the same time, it can reasonably allocate resources and improve the overall mapping efficiency.

[0090] The beneficial effects of the above technical solution are as follows: By adopting the solution provided in this embodiment, through the preliminary screening of remote sensing image technology, it is possible to quickly locate the target images that may have problems, avoiding the cumbersome steps of a large number of manual reviews in traditional methods; at the same time, through the careful analysis of the resolution of the target images, the system can accurately identify the key areas that need further analysis and confirmation, which not only improves the pertinence of information mapping but also effectively avoids waste of resources; in addition, using the area monitoring level database, the system can evaluate the monitoring level according to the importance of the environmental protection of the area, thus ensuring the priority of information collection and the rationality of resource allocation.

[0091] In one embodiment, use ground measurement equipment to optimize some content of the basic information to obtain the optimized basic information, including:

[0092] Determine the part of the basic information to be optimized;

[0093] Using ground measurement equipment, conduct on-site information verification or supplementary information collection for the area corresponding to some content, and obtain supplementary information and verified accurate information;

[0094] According to the supplementary information and verified accurate information, combined with the basic information, obtain the optimized basic information.

[0095] The working principle of the above technical solution is as follows: In order to implement the technical solution of using ground measurement equipment to optimize some content of the basic information and obtain the optimized basic information, the present invention will intelligently judge which basic information content needs to be further optimized based on the information provided by the previous remote sensing image analysis and the regional monitoring level database; this process is based on big data analysis and comprehensively considers various factors, such as the importance of regional environmental protection and historical problem records, to ensure the accuracy and efficiency of optimization; subsequently, ground measurement equipment will be dispatched to the designated area to be optimized, and these equipment may include high-precision GPS locators, environmental sensors, high-definition cameras carried by drones, etc., which can verify the accuracy of the basic information on-site and collect missing or ambiguous supplementary information. For example, for some details that are difficult to identify in remote sensing images, ground measurement equipment can take high-definition photos at close range to obtain more accurate data; after obtaining the supplementary information and verified accurate information, the system will compare and integrate this information with the original basic information. Through advanced algorithms, the system can intelligently identify and eliminate incorrect information, retain and optimize accurate information, and supplement new valid information at the same time, and finally generate the optimized basic information; this process not only improves the accuracy and integrity of the information, but also provides more reliable data support for subsequent analysis and decision-making.

[0096] The beneficial effects of the above technical solution are as follows: By adopting the solution provided in this embodiment, through the intelligent judgment of the previous remote sensing image analysis and the regional monitoring level database, it is possible to targetedly optimize the basic information of key areas, avoiding the waste of resources caused by comprehensive mapping; secondly, the precise collection and verification of ground measurement equipment ensure the accuracy and integrity of the information, especially for the details that are difficult to identify in remote sensing images, providing more reliable supplementary information; furthermore, through the intelligent identification and optimization of algorithms, the accuracy and effectiveness of the information are further improved, providing a solid data basis for subsequent analysis and decision-making; finally, the entire technical solution realizes the full automation from information acquisition to optimization processing, greatly improving the work efficiency and reducing the labor cost.

[0097] In one embodiment, determining the part of the basic information to be optimized includes:

[0098] Obtain the first remote sensing image in the basic information whose image resolution is less than the set resolution threshold;

[0099] Using the set resolution conversion model, convert the first remote sensing image according to one or more set resolutions to obtain a second remote sensing image with the converted resolution;

[0100] Using the set YOLO object detection model, perform object detection on the second remote sensing image to obtain a number of object detection points; cluster the object detection points to obtain a number of clusters;

[0101] Statistically calculate the number and area of the clusters;

[0102] Set the first weight value for the number and the second weight value for the area;

[0103] Perform a summation calculation on the product of the number and the first weight value and the product of the area and the second weight value to obtain an effect evaluation value for evaluating the object detection effect of the second remote sensing image;

[0104] If the effect evaluation value is less than the set effect evaluation threshold, then use the corresponding second remote sensing image as a part of the content to be optimized in the basic information.

[0105] The working principle of the above technical solution is: In order to determine the part of the content to be optimized in the basic information, the present invention first screens out the remote sensing images with relatively low image resolution in the basic information by setting a resolution threshold. These images may not accurately reflect the information of the power transmission line and its surrounding environment due to insufficient resolution, so they need to be optimized; then, using the resolution conversion model, convert these low-resolution remote sensing images into images with higher resolution, thereby enhancing the image details and improving the accuracy of information extraction; subsequently, use the YOLO object detection model to perform object detection on the converted remote sensing image. This model can efficiently and accurately identify key objects in the image, such as power transmission lines, water bodies, vegetation, etc., and generate object detection points; by performing clustering analysis on these object detection points, similar object points can be further grouped into a set to form clusters, so as to more intuitively display the object distribution in the image; after obtaining the clusters, by statistically calculating the number and area of the clusters, the number and scale of the objects in the image can be quantitatively analyzed, providing a basis for subsequent optimization work; at the same time, according to actual needs, set the first weight value and the second weight value for the number and the area respectively to reflect their importance in the evaluation of the object detection effect; finally, by performing a summation calculation on the product of the number and the first weight value and the product of the area and the second weight value, an effect evaluation value is obtained. If this value is less than the set effect evaluation threshold, it means that the corresponding second remote sensing image has deficiencies in object detection and needs to be further optimized as a part of the content to be optimized in the basic information.

[0106] The beneficial effects of the above technical solution are as follows: By adopting the solution provided in this embodiment, through the resolution conversion model in combination with the YOLO object detection model and the clustering algorithm, the second remote sensing image is analyzed, ensuring that the mapping system can effectively identify and optimize the problem of insufficient image resolution, thereby improving the accuracy and efficiency of the mapping of the environmental protection information of the power transmission and transformation lines.

[0107] In one embodiment, using ground measurement equipment, on-site information verification or supplementary information collection is carried out on the area corresponding to some content to obtain supplementary information and verified accurate information, including:

[0108] Using ground measurement equipment, on-site information verification is carried out on the area corresponding to some content to determine whether the second remote sensing image corresponding to some content is available. If it is available, corresponding annotation is carried out to obtain verified accurate information; if it is not available, based on the second remote sensing image, a judgment on the missing image content or the need for supplementary shooting is made to obtain a judgment result;

[0109] According to the judgment result, supplementary image acquisition is implemented to obtain supplementary information;

[0110] Based on the second remote sensing image, a judgment on the missing image content or the need for supplementary shooting is made to obtain a judgment result, including:

[0111] Based on the set image feature database, the image features of the second remote sensing image are compared with the image feature data in the image feature database for similarity. If the similarity is less than the set similarity threshold, it is determined that supplementary shooting is required; if the similarity is greater than the set similarity threshold, the category attribute of the second remote control image is obtained; according to the category attribute, using the set category defect database, a matching judgment on the image content defect is implemented. If there is a matching situation, a judgment result of missing image content is obtained.

[0112] The working principle of the above technical solution is as follows: Through the combination of ground measurement equipment and remote sensing technology, refined mapping of the environmental protection and water conservation information of transmission and transformation lines is achieved. First, the ground measurement equipment conducts on-site verification of areas in the remote sensing image that may be in doubt or blurred, which ensures the accuracy of the data. If the verification result shows that the information of a certain part of the remote sensing image is available, the system will accurately mark it on the image, which not only improves the readability of the information but also provides strong support for subsequent analysis and decision-making. For the parts of the remote sensing image determined to be unavailable after verification, the system will further analyze the image content to determine whether key information is missing or additional shooting is required. This step relies on the image feature database. By comparing the similarity of the image features stored in the database, the system can intelligently identify the areas that need to be supplemented or corrected. If the similarity is lower than the set threshold, it indicates that there is a large difference between the current image and the standard image in the database, and further on-site shooting is required to supplement the information. In addition, it also has a matching judgment function for image content defects. For remote sensing images with a similarity higher than the threshold, the system will search for possible defect patterns in the category defect database according to their category attributes. Once a matching situation is found, the system will determine that the image content is missing or requires special attention, thus guiding subsequent information supplementation and correction work.

[0113] The beneficial effects of the above technical solution are as follows: By adopting the solution provided in this embodiment, through the collaborative action of ground measurement and remote sensing technology, comprehensive and accurate mapping of the environmental protection and water conservation information of transmission and transformation lines is achieved, providing solid data support for environmental protection and the safe operation of power facilities.

[0114] In one embodiment, it further includes a resolution optimization and adjustment module, and the resolution optimization and adjustment module is used for:

[0115] Configure an environmental sensor in the ground measurement equipment, and use the environmental sensor to collect the environmental data around the transmission and transformation line in real time; the environmental data includes the current light intensity L and the atmospheric turbulence coefficient r;

[0116] Construct an adaptive resolution adjustment formula, and dynamically adjust the flight height h of the unmanned aerial vehicle and the satellite focal length f through a non-linear mapping function to optimize and adjust the resolution of the images taken by the high-resolution satellite and the unmanned aerial vehicle. The resolution calculation formula is:

[0117]

[0118] In the above formula, R represents the resolution of the captured image, k1 and k2 represent calibration constants, f represents the focal length of the high-resolution satellite, the larger the focal length, the higher the image resolution, h represents the flight altitude of the drone, and an increase in the flight altitude will reduce the ground resolution. r represents the atmospheric turbulence coefficient, which characterizes the intensity of air disturbance. The larger the atmospheric turbulence coefficient, the higher the degree of image blurring and the lower the resolution. L represents the current light intensity, and L0 represents the reference light intensity; h*(1 + k2*r) represents the negative impact of the flight altitude and atmospheric turbulence on the resolution, while k1*f is the positive impact of the focal length on the resolution. The calibration constants k1 and k2 are used to adjust the weights of these impacts; used to convert the light intensity ratio using the arctangent function into an angular value within a finite interval, which is used to adjust the sensitivity of the resolution and prevent numerical instability under extreme light conditions;

[0119] The peak signal-to-noise ratio is used to evaluate the quality of the captured images of the high-resolution satellite and the drone. If the quality is less than the set quality threshold, the re-shooting mechanism is dynamically triggered to control the high-resolution satellite and the drone to perform image re-capture; the basic formula for the peak signal-to-noise ratio is:

[0120]

[0121] where P represents the peak signal-to-noise ratio, MAX represents the maximum possible value of the image pixels, M*N represents the image resolution, H(i, j) represents the pixel value of the original image at the position (i, j); K(i, j) represents the pixel value of the reconstructed image at the position (i, j), represents the mean square of the pixel-by-pixel differences between the original image and the reconstructed image; log 10 represents the logarithmic transformation, which converts the linear scale of the mean square to the logarithmic scale in decibels, compressing the numerical range to facilitate the comparison of quality differences in different scenarios; the larger the value of P, the better the image quality.

[0122] The working principle of the above technical solution is as follows: During the monitoring of power transmission and transformation lines under mountainous conditions and adverse weather, the complex terrain leads to uneven illumination, and night weather and rainy conditions will affect the quality of shooting. Atmospheric turbulence will also significantly reduce the resolution. In order to capture the images of power transmission and transformation lines under adverse climate conditions more clearly and accurately, the present invention integrates environmental sensors in ground measurement equipment to be able to capture key environmental parameters around the power transmission and transformation lines in real time, such as illumination intensity and atmospheric turbulence coefficient. These environmental data are then input into the resolution optimization and adjustment module, which uses an adaptive resolution adjustment formula and combines a non-linear mapping function to finely and dynamically adjust the flight altitude of the unmanned aerial vehicle and the satellite focal length. This adjustment aims to minimize the adverse effects of environmental factors on the resolution of the captured images, and at the same time utilize the positive effect of the focal length to improve the image quality. During the adjustment process, the system comprehensively considers the reduction of ground resolution caused by the increase in flight altitude, the image blurring caused by atmospheric turbulence, and the influence of illumination intensity change on resolution sensitivity, adjusts the weights of these influencing factors through calibration constants, and converts the illumination intensity ratio using the arctangent function. The system ensures the accuracy and stability of the resolution adjustment, and can maintain the stability of the values even under extreme illumination conditions. After the shooting is completed, the peak signal-to-noise ratio is used as an evaluation index to evaluate the quality of the images captured by the high-resolution satellite and the unmanned aerial vehicle. If the image quality is lower than the preset quality threshold, the system will automatically trigger the reshooting mechanism to command the high-resolution satellite and the unmanned aerial vehicle to perform image reshooting to ensure the accuracy and reliability of the obtained environmental protection information related to water and soil. This workflow not only improves the mapping efficiency but also effectively guarantees the monitoring accuracy of the environment around the power transmission and transformation lines.

[0123] The beneficial effects of the above technical solution are as follows: By adopting the solution provided in this embodiment, through the analysis of the real-time environmental data around the power transmission and transformation lines and using the analysis results as feedback to optimize and adjust the shooting resolution of the high-resolution satellite and the unmanned aerial vehicle. The resolution calculation formula is modeled through multi-parameter coupling, which organically combines environmental interference (turbulence, illumination) with equipment performance (focal length, altitude) to achieve dynamic optimization of the resolution. And by evaluating the quality of the captured images, when the quality does not meet the expectations, controlling the high-resolution satellite and the unmanned aerial vehicle to perform reshooting can ensure the quality of the captured images to the greatest extent, providing essential conditions for improving the reliability and efficiency of the environmental protection monitoring of water and soil around the power transmission and transformation lines, and can significantly improve the image shooting quality of the power transmission and transformation lines in complex environments.
