[0002] Power grid construction projects are characterized by long engineering paths, complex terrain, complex meteorological conditions, and many ecologically sensitive areas. Due to earthwork excavation, vegetation disturbance, and improper disposal of abandoned soil, ecological damage and soil erosion are easily caused. Management and control mainly rely on manual on-site supervision, which is time-consuming, inefficient, and has a narrow coverage. It is difficult to discover and rectify existing problems in a timely manner, which not only affects the smooth progress of independent acceptance work. In the independent acceptance of power grid construction in recent years, construction units have arbitrarily expanded the scope of disturbance, arbitrarily dumped abandoned soil and slag, and failed to restore construction roads in a timely manner. These undesirable phenomena not only affect the progress of acceptance, but are also frequently required to be rectified by regulatory authorities.

[0021] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0022] like Figure 1 As shown, an environmental protection verification method for a power transmission project construction process provided by an embodiment of the present invention includes the following steps:

[0023] An initial pole tower image is collected by a camera device, wherein the initial pole tower image is a picture collected by the camera device when the pole tower construction of the power transmission project begins, and a plurality of initial infrastructure sensitive points, design construction road marks and design construction area marks are constructed based on the initial pole tower image to obtain an initial infrastructure pole tower image;

[0024] The pole tower image is collected by a camera device, wherein the pole tower image is a picture collected by the camera device when the construction of the same pole tower of the power transmission project is completed, and multiple actual infrastructure sensitive points, actual construction road marks and actual construction area marks are constructed based on the pole tower image to obtain an infrastructure pole tower image;

[0025] performing intersection calculations on the multiple actual infrastructure sensitive points and the actual construction road marks in the infrastructure tower image respectively to obtain multiple intersecting infrastructure sensitive points, comparing the multiple intersecting infrastructure sensitive points with the multiple initial infrastructure sensitive points in the initial infrastructure tower image to obtain multiple changing infrastructure sensitive points, performing ratio calculations on the designed construction road marks in the initial infrastructure tower image and the actual construction road marks in the infrastructure tower image to obtain a path change rate, performing area expansion statistics according to the designed construction area marks in the initial infrastructure tower image and the actual construction area marks in the infrastructure tower image to obtain the number of expanded towers;

[0026] An environmental protection verification report is generated based on the plurality of intersecting infrastructure sensitive points, the path change rate and the number of expanded towers.

[0027] It should be understood that images of poles and towers can be collected according to the construction cycle, and construction environmental protection inspections can be carried out in different construction cycles according to the method to achieve comprehensive supervision during the construction period. In the early stage of engineering construction, during the construction process, and at the completion stage, an environmental protection information platform is built to manage the data related to the poles and towers during the entire construction process, and the environmental protection work of the entire construction process of the transmission project is inspected in combination with this method.

[0028] In an embodiment of the present invention, in response to the supervision requirements for the implementation of environmental protection at the construction site, the construction specifications of the construction site are supervised based on the collected images, the infrastructure sensitive points, construction roads and construction areas before and after construction are combined with the tower construction site images, the disturbance area of ​​the tower area is analyzed, the path changes are analyzed, and the infrastructure sensitive points are counted, so as to provide support for the environmental protection acceptance of the project.

[0029] Preferably, the camera equipment is a drone. The shooting pixel of the digital camera carried by the drone is not less than 12 million, and it has GPS positioning and date and time display functions. The drone aerial photography is carried out in three stages: before construction, during construction (the line construction process is divided into foundation, tower assembly, and line stringing, and the converter construction station process is divided into four connections and one leveling, civil engineering, electrical, and debugging), and final acceptance. The drone aerial photography is panoramic, shooting the line project tower base and tower base construction area, the area within 50 meters outside the boundary of the abandoned soil and slag area, and the area within 50 meters outside the boundary of the converter station project. The implementation of various environmental protection measures at the construction site must cover the complete disturbance range of the site.

[0030] When photographing the tower base, take at least 1-2 vertical photos and 2-4 photos at different angles. The recommended angle is 45-60 degrees and the height is about 100m. The number of drone aerial images for each tower is not less than 5, and the number of images for each converter station is not less than 10. Multiple drone aerial images should form a continuous scene. After the aerial photography is completed, download the POS data and airborne GPS data in time, and copy the image data.

[0031] UAV aerial image data preprocessing includes conventional processing procedures such as image data preprocessing, relative orientation, absolute orientation, point cloud data extraction, orthophoto generation, etc. For the distortion-corrected UAV images, the Inpho software platform is used to perform engineering establishment, aerial triangulation, digital elevation model production, orthophoto production, etc. The specific operation process includes:

[0032] 1) Data preparation, using Pegasus UAV to complete POS differential: including the poor stability of the drone's flight attitude and the low initial POS accuracy. In order to reduce the workload of external control point deployment, try to set up base stations, and use differential POS with a small number of external control points to obtain high-precision three-dimensional aerial triangulation results. Use the built-in differential GPS module of the Pegasus UAV butler to complete POS differential, and complete the conversion from WGS84 to the target coordinate system through the seven parameters of the survey area. The differential POS position accuracy is at the centimeter level, and the seven-parameter conversion will also introduce centimeter-level conversion accuracy errors.

[0033] 2) Image distortion preprocessing: including the use of platform self-calibration or laboratory indoor calibration to solve image distortion parameters. Platform self-calibration: The platform self-calibration completes image distortion correction, and performs aerial triangle encryption and accuracy inspection respectively; the platform self-calibration in the test area does not meet the aerial triangle accuracy requirements in the relative orientation link. Therefore, the indoor calibration method is used to ensure the 1:2000 stereo mapping accuracy of the project.

[0034] Indoor calibration: Input the camera parameters obtained by Pegasus indoor calibration into the image distortion tool to correct image distortion. The platform performs aerial triangle encryption and accuracy inspection, and the aerial triangle results meet the experimental objectives.

[0035] 3) Project establishment and aerial triangle encryption: Including UASMaster, according to the distribution characteristics of the survey area, the project is reasonably established in sections (image size ≤ 20 million), click on the connection point matching, complete the relative orientation, and complete the overall project accuracy control through the edge connection in the later stage. Relative orientation is an important part of the entire aerial triangle. After the connection points are matched, the overall distribution is uniform; most single-chip connection points are more than 400, and the connection degree of each point is mostly higher than 5flods. From the perspective of global matching distribution, the connection points are evenly matched.

[0036] 4) Mosaic orthophoto: In the OrthoVista module, the corrected single slice is generated, and the DOM of each flight strip is output in sections to complete the orthophoto generation of the entire test area.

[0037] Preferably, the constructing a plurality of initial infrastructure sensitive points based on the initial tower image includes:

[0038] If there are sensitive buildings within the preset range of the pole tower, the positioning information of the sensitive buildings is obtained through a positioning device, and a plurality of initial infrastructure sensitive points are constructed on the initial pole tower image according to the positioning information.

[0039] It should be understood that this embodiment is also applicable to the step of constructing a plurality of actual infrastructure sensitive points based on the tower image.

[0040] In the embodiment of the present invention, the sensitive building positioning is combined with the tower image to analyze the special areas affected by the construction process.

[0041] Preferably, after the step of obtaining the initial infrastructure tower image, the method further comprises:

[0042] Import the satellite map, mark a plurality of initial infrastructure sensitive points, design and construction road marks and design and construction area marks in the satellite map, upload the image of the sensitive building to the satellite map, and obtain the sensitive point thematic map.

[0043] Specifically, with the satellite map as the base map, engineering lines, sensitive points, and monitoring points can be loaded, and the vertical distance from the monitoring point to the engineering line can be generated and the distance can be marked (such as 10 meters), and the on-site pictures of sensitive points can be loaded. If the monitoring point data is missing, the monitoring point can be manually drawn, and the vertical distance from the monitoring point to the engineering line can be automatically or manually drawn and marked. The selected sensitive point can be displayed in the sensitive point list through search; if the sensitive point has generated a thematic map, it can be displayed in the thematic map preview function area.

[0044] In the embodiment of the present invention, the infrastructure information of the tower is uploaded in the satellite map, and the thematic map of the corresponding area can be quickly searched according to the name of the sensitive point to manage the sensitive point.

[0045] Preferably, the step of respectively performing intersection calculation on the plurality of actual infrastructure sensitive points in the infrastructure tower image and the actual construction road marking to obtain a plurality of intersecting infrastructure sensitive points includes:

[0046] A first environmental buffer zone is generated with the actual construction road mark in the infrastructure tower image as the center and at a first preset distance, and a second environmental buffer zone is generated with the actual construction road mark as the center and at a second preset distance, and a difference set between the first environmental buffer zone and the second environmental buffer zone is calculated to obtain a third environmental buffer zone. Intersection calculation is performed on the sensitive areas corresponding to the multiple actual infrastructure sensitive points and the third environmental buffer zone to obtain multiple intersecting infrastructure sensitive points.

[0047] It should be understood that ecological and environmental sensitive targets include ecological sensitive areas (such as scenic spots, nature reserves, drinking water source protection areas, and world cultural and natural heritage sites) and residential sensitive points (such as electromagnetic environment and noise monitoring points). Figure 2 As shown, virtual road B and virtual road B' are 18 meters away from the actual construction road mark A (i.e., the first preset distance), and an 18-meter buffer zone (i.e., the first environmental buffer zone) is generated between the actual construction road mark A and virtual road B and virtual road B' respectively; virtual road C and virtual road C' are 61 meters away from the actual construction road mark A (i.e., the second preset distance), and a 61-meter buffer zone (i.e., the second environmental buffer zone) is generated between the actual construction road mark A and virtual road C and virtual road C' respectively; a 43-meter buffer zone (i.e., the third environmental buffer zone) is generated between virtual road B and virtual road C and between virtual road B' and virtual road C'. The number of sensitive points crossed is calculated by finding the intersection of the engineering path (1) and the sensitive area; for sensitive areas crossed multiple times by the line, only one is counted.

[0048] In the embodiment of the present invention, sensitive points in the vicinity of the pole tower are supervised according to a buffer zone with a preset distance from the pole tower.

[0049] Preferably, the calculating the ratio of the designed construction road mark in the initial infrastructure tower image to the actual construction road mark in the infrastructure tower image to obtain the path change rate includes:

[0050] A corresponding road buffer zone is generated according to a plurality of different preset distances with the actual construction road mark in the infrastructure tower image as the center, and the intersection distances of the designed construction road mark in the initial infrastructure tower image in the plurality of road buffer zones are calculated respectively to obtain a plurality of intersection lengths, and a ratio of the plurality of intersection lengths to the designed construction road mark length is calculated to obtain a path change rate.

[0051] It should be understood that Figure 3As shown in the figure, according to the selected provincial section, the design construction road mark D and the actual construction road mark E are divided, and the percentage of the length of road D that changes from 0 to 50 meters, 50 to 300 meters, 300 to 500 meters and above 500 meters in the total length of road D is calculated compared with road E. With the actual construction road mark E as the center, virtual road F and virtual road F' are set at a distance of 50 meters to generate a 50-meter buffer zone; virtual road G and virtual road G' are set at a distance of 300 meters to generate a 300-meter buffer zone; virtual road H and virtual road H' are set at a distance of 500 meters to generate a 500-meter buffer zone. The intersection of each buffer zone and road D is calculated to obtain the intersection length of road D, and the ratio of the intersection length to the total length of road D is calculated to obtain the path change rate; when the intersection length is greater than 500 meters, the total length of road D is subtracted from the sum of the intersection lengths of other intervals to obtain the far intersection length, and then the ratio of the far intersection length to the total length of road D is calculated to obtain the path change rate.

[0052] In the embodiment of the present invention, the change of the construction road during the construction process is analyzed, and the degree of path change is analyzed according to the change rate.

[0053] Preferably, the performing area expansion statistics according to the designed construction area mark in the initial infrastructure tower image and the actual construction area mark in the infrastructure tower image to obtain the number of expanded towers includes:

[0054] A ratio calculation is performed on the designed construction area mark in the initial infrastructure tower image and the actual construction area mark in the infrastructure tower image to obtain an area disturbance rate. When the area disturbance rate is greater than a preset threshold, the tower is determined to be an expanded tower, and the number of expanded towers is obtained.

[0055] In the embodiment of the present invention, the initially planned construction area and the completed construction area are calculated, and the number of poles and towers in the completed construction area is calculated.

[0056] Preferably, after the step of obtaining the infrastructure tower image, the method further comprises:

[0057] The infrastructure tower image is made into an orthophoto map by using POS technology, and the features of the orthophoto map are extracted by using the Haralick algorithm to obtain a texture feature map. The features of the orthophoto map are extracted by using the Hough transform algorithm to obtain a shape feature map. The Euclidean distance between the object corresponding to the shape feature map and the tower is calculated by using the Euclidean distance calculation expression to obtain the spatial distance.

[0058] Specifically, the interpretation marks of the orthophoto image of the infrastructure tower image are judged based on the texture features, shape features and other features of the image, including:

[0059] Gray-level co-occurrence matrix is ​​a method for extracting texture features proposed by Haralick. It reflects the spatial structural information of different gray-level pixels through the spatial correlation characteristics of gray-level, calculates the correlation of gray-levels of two pixels at a certain distance in the image, and obtains the gray-level status of two pixels at a certain distance on the image. Texture features are unique classification features in object-oriented classification methods. They are formed by the appearance of gray-levels at two pixel positions and mainly reflect the external characteristics of the internal parts of the objects in the image.

[0060] In object-oriented segmentation, objects have shape features relative to pixels. Shape features are more effective in extracting relatively regular and linear features, such as roads, rivers, houses, etc. The shape features of object-oriented classification mainly include the area, length, aspect ratio, rectangle fit, shape index, etc. of the object.

[0061] In some cases, other features are also used to classify images. For example, in areas with large differences in terrain height, the slope factor will have a greater impact on the distribution of features, which can be extracted using the hydrology module in the ARCGIS tool. Generally speaking, if there are more residential areas near the tower base, the altitude is also lower and the slope is gentler; retaining walls are generally distributed in areas with a certain slope. In addition, spatial relationship is also a very important feature in object-oriented, among which spatial distance is also a commonly used feature. For example, the distance between the loading yard and the tensioning yard and the tower base area is close.

[0062] In the embodiment of the present invention, feature extraction is performed on the infrastructure tower image to accurately interpret the image based on the obtained features.

[0063] Preferably, after the step of obtaining the infrastructure tower image, the method further comprises:

[0064] The texture feature map, the shape feature map and the spatial distance are interpreted according to the constructed environmental interpretation mark library to obtain an environmental interpretation mark, shape parameters are generated based on the shape feature map, and the shape parameters are compared with preset parameters to obtain an environmental verification result. The environmental verification result is added to the environmental verification report.

[0065] It should be understood that the shape parameters include the environmental protection feature area, the environmental protection feature length, and the environmental protection feature width, and the environmental protection interpretation mark is a mark in the environmental protection interpretation mark library.

[0066] Special measures are designed according to the topography of the tower location, mainly including slope protection, retaining walls, intercepting drainage ditches, vegetation restoration design in the tower base area, and vegetation restoration design for temporary occupied areas such as crossing sites, tensioning sites, and construction roads.

[0067] Preferably, after the step of obtaining the shape feature map, the method further comprises:

[0068] If the shape feature map is a road feature, it is determined whether the road feature is complete. If it is incomplete, it is determined to be a continued road, and a reshoot instruction is generated to collect a tower image of the complete road.

[0069] Three types of sign libraries were established, namely, interpretation signs for work measures, land disturbance interpretation sign library and problem feature interpretation sign library.

[0070] The measure interpretation symbol library includes: land reclamation, farmland restoration, grass grid sand barrier, gravel cover, drainage ditch, slope protection, retaining wall, limit, thatch, paving / isolation, temporary barrier, and vegetation restoration.

[0071] The land disturbance interpretation sign library includes: tower base area, vehicle road, cableway, human lift road, tensioning field, and cableway loading / unloading points.

[0072] The problem feature interpretation sign library includes: landslides and debris, gullies, ground subsidence, water accumulation, construction materials occupying vegetation / random stacking and storage, untreated surplus soil, substandard land reclamation, and failure to dismantle the cableway.

[0073] Specifically, the verification of the land disturbance area includes: summarizing the construction disturbance area of ​​the tower base area by section, summarizing the number of towers that have been started, the number of tower bases that exceed the standard, the design area, the construction disturbance area, and the measured disturbance rate. Specifically: the number of towers only includes the number of tower bases covered by this flight (i.e., the drone takes pictures of the tower construction process), the measured disturbance rate is equal to the construction disturbance area divided by the design area, and the number of tower bases that exceed the standard is the number of towers with a measured disturbance rate greater than 100%.

[0074] The verification of the newly added construction roads, manned roads and cableways includes: summarizing the newly added construction roads by section, divided into total area, total length, average width, corresponding number of poles and towers, and the number of poles and towers corresponding to the road continuation.

[0075] The verification of the implementation of environmental protection measures includes: statistics on the implementation of engineering measures and temporary measures respectively. The statistics are divided into the type of measures, the area of ​​measures and the length of measures. Specifically, the type of measures, the area of ​​measures and the length of measures are interpreted through aerial images; the length of limit measures is counted; the area of ​​​​thatching, paving, and woven bag blocking measures is counted; the length and width of retaining walls and intercepting drainage ditches are counted.

[0076] The verification of landslides, debris flow and gullies in hilly areas includes: based on aerial photography, separately counting the landslides, debris flow and gullies in the tower base area and construction roads, summarizing them by section, and listing the tower numbers corresponding to the problems one by one.

[0077] The verification of ecological sensitive points includes: combining the environmental impact assessment report and reviewing the situation of routes crossing ecologically sensitive areas based on aerial photography.

[0078] The verification of residential sensitive points includes: taking the pole tower path as the center line, making 7m and 50m outside the edge conductor, and 7m to 50m outside the edge conductor as the residential sensitive points. Verification is carried out in villages according to the original sensitive point data.

[0079] The inspection of vegetation restoration or recultivation includes: interpreting the implementation and effect of vegetation restoration and recultivation in aerial photography of the entire line, counting tower bases with obvious effects, and summarizing them by section to assist in environmental protection acceptance. It is summarized in three dimensions: the number of poles and towers, the number of poles and towers that have completed vegetation restoration or recultivation, and the proportion of restoration. Specifically, the vegetation restoration and recultivation situation is interpreted through aerial photography; vegetation restoration means that the vegetation restoration effect within the disturbance range is obvious, that is, it has been obviously greened; recultivated means that the recultivation effect within the disturbance range is obvious, that is, the crops have been obviously greened or there are obvious and neat traces of mechanized farming.

[0080] The verification of house demolition and site restoration includes: based on aerial images, statistics on house demolition within 7m outside the boundary line.

[0081] Line change verification includes: combining the tower coordinates and interpreting whether the tower is offset based on aerial photography. Rules for judging whether the tower is offset: if the original coordinate point is within the range of the four tower legs for the tower foundation that has been started, it is considered that there is no offset; if the original coordinate point is outside the range of the four tower legs for the tower foundation that has been started, it is considered that there is an offset. The offset coordinates need to be counted to form the lateral swing length.

[0082] In the embodiment of the present invention, a complete environmental protection interpretation symbol library is established based on standardized data to assist in the environmental protection house demolition and site restoration implementation judgment, the identification, analysis and judgment of environmental sensitivity changes, the environmental protection design measures in the tower base area and the implementation status, so as to realize multi-dimensional statistics and analysis according to whether it is implemented, the type of measures, and the section to which it belongs.
