[0029] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0030] It should be noted that the acquisition, storage, use, and processing of data in the technical solution of the present invention are in compliance with the relevant provisions of relevant laws and regulations.

[0031] The following describes, with reference to the accompanying drawings, a method, device, electronic device, and storage medium for determining the amount of reservoir sedimentation and effective storage capacity according to an embodiment of the present invention.

[0032] Figure 1 A schematic flow chart of a method for determining the amount of sediment deposition and effective storage capacity of a reservoir provided in an embodiment of the present invention.

[0033] like Figure 1 As shown, the method comprises the following steps:

[0034] Step 101, obtain a bird's-eye view of the entire reservoir, on which two reference positioning points around the reservoir area are marked, and calculate the scale between the bird's-eye view and the entire reservoir based on the horizontal distance between the two reference positioning points on the bird's-eye view and the measured horizontal distance between the two reference positioning points in the entire reservoir.

[0035] In some embodiments, a bird's-eye view of the entire reservoir at any water level can be obtained by synthesizing the camera shots at a high position of the reservoir or by taking drone shots. In order to avoid errors caused by the tilt of the camera shooting angle, the angle should be kept level each time the camera is shot.

[0036] In order to correctly convert the scale between the bird's-eye view and the entire reservoir, two fixed and easily identifiable points around the reservoir area should be selected on the bird's-eye view as reference points (e.g., points A and B). The positions of the reference points should be relatively fixed and the horizontal distance should be easy to obtain.

[0037] It is understandable that the two reference positioning points A and B may be fixed buildings or marked objects, but are not limited thereto, and this embodiment does not make any specific limitation thereto.

[0038] Step 102, obtaining a plurality of different water levels H1, H2, ..., H n The top view of the entire reservoir is obtained, the perimeter of the reservoir area in each top view is identified, and the total area S1, S2, ..., S of the reservoir area at different perimeters is calculated based on each perimeter and scale. n , where n is the dead water level of the reservoir.

[0039] In some embodiments, a plurality of different water levels H1, H2, ..., H n The top view of the entire reservoir is obtained, the perimeter of the reservoir area in each top view is identified, and the total area S1, S2, ..., S of the reservoir area at different perimeters is calculated based on each perimeter and scale. n One implementation method may be to obtain a plurality of different water levels H1, H2, ..., H n The whole reservoir is viewed from above, and the perimeter of the reservoir area in each view is identified by image recognition software; the reservoir area within the perimeter of each view is filled with white pixels, and the area of ​​each area filled with white pixels is calculated by image processing software; the product of the area of ​​each area filled with white pixels and the scale is used as the total area S1, S2, ..., S of the reservoir area at different perimeters. n , wherein the image processing software may include but is not limited to Photoshop.

[0040] Optionally, when the perimeter of the reservoir area in each overhead view is automatically identified by image recognition software, a manual conformity check may be performed to manually modify the incorrectly identified perimeter to ensure that the perimeter of the reservoir area is accurately obtained.

[0041] Furthermore, an embodiment of the present invention provides a schematic diagram of pixel filling in a top view of the entire reservoir, such as Figure 2 As shown, specifically, after the perimeter of the reservoir area in the overhead view is identified by image recognition software, the reservoir area (reservoir) within the corresponding perimeter of the overhead view is filled with white pixels, the land outside the reservoir area is filled with gray pixels, and two reference positioning points A and B are calibrated on the overhead view.

[0042] In addition, the embodiment of the present invention also provides a schematic diagram of pixel filling of multiple top views of the entire reservoir, such as Figure 3 As shown, the perimeter (shape) of the reservoir area in the top view under multiple different water levels is identified by image recognition software, and the reservoir area within the corresponding perimeter of each top view is filled with white pixels, and the land outside the reservoir area is filled with gray pixels. Points A and B are used as reference positioning points, and points A and B of each top view are overlapped to obtain the change of the perimeter under different water levels (the contour of the water surface corresponding to different water levels). Therefore, since the positions of the two reference positioning points A and B are always determined, the horizontal distance of the AB line is also fixed, which can be directly measured by measuring or consulting the online map and the distance measurement tool in the map. The scale between the top view and the entire reservoir can be determined by the horizontal distance of AB. At the same time, the area of ​​the area filled with white pixels in each top view is directly calculated by image processing software, and then multiplied by the scale to obtain the total area of ​​the reservoir area under different water levels.

[0043] Step 103: when the space of the reservoir area is composed of multiple barrel-shaped bodies, according to H1, H2, ..., H n and S1, S2, ..., S n , calculate the effective storage capacity of the reservoir between adjacent water levels, and add up the effective storage capacity of the reservoir between adjacent water levels to obtain the total effective storage capacity of the reservoir.

[0044] In some embodiments, when the space of the reservoir area is composed of multiple barrels, according to H1, H2, ..., H n and S1, S2, ..., S n , calculate the effective storage capacity of the reservoir between adjacent water levels, and add up the effective storage capacity of the reservoir between adjacent water levels to obtain the total effective storage capacity of the reservoir. One implementation method may be, when the space of the reservoir area is composed of multiple barrel-shaped bodies superimposed, according to H1, H2, ..., H n and S1, S2, ..., S n , calculate the effective storage capacity V1, V2, ..., V between adjacent water levels n-1 , where V1 = 1 / 2 * (H1-H2)*(S1+S2),...,V n-1 =1 / 2 * (H n-1 -H n )*(S n-1 +S n );The effective storage capacity of the reservoir between adjacent water levels V1, V2, ..., V n-1 Add them up to get the total effective storage capacity of the reservoir V = V1 + V2 + V n-1Therefore, the acquisition and processing of the reservoir's bird's-eye view, the selection of reference positioning points and the determination of the effective storage capacity are given, fully considering the operability and accuracy.

[0045] Among them, different water levels H1, H2, ..., H n The total area of ​​the reservoir area S1, S2, ..., S n The corresponding relationship is shown in Table 1.

[0046] Table 1 Correspondence between different water levels and the total area of ​​the reservoir area

[0047]

[0048]

[0049] Step 104, based on the first total area and the second total area of ​​the reservoir area at the same water level at two time points, calculate the decomposition position depth H of the sediment scouring section and the sedimentation section in the reservoir within the time interval of the two time points k , and based on the first time point H k The effective storage capacity of the reservoir below the depth V0 and the second time point H k The effective storage capacity V of the reservoir below the depth is used to calculate the amount of silt deposited in the reservoir during the time interval.

[0050] In some embodiments, siltation mainly occurs at the bottom of the reservoir and below a certain depth, and the water surface area of ​​the reservoir decreases. Scour is likely to occur above a certain depth, that is, the water surface area increases, such as Figure 4 As shown, Figure 4 An embodiment of the present invention provides a schematic diagram of siltation and scouring at the bottom of a reservoir. Specifically, the daily highest water level of the reservoir, the siltation section and the scouring section of the bottom of the reservoir, the dead water level position (the part below the dead water level position does not affect the effective storage capacity) and (the original bottom of the reservoir) are divided. After the siltation and scouring at the bottom of the reservoir, the bottom of the reservoir after siltation / scouring can be obtained.

[0051] In some embodiments, based on the first total area and the second total area of ​​the reservoir area at multiple same water levels at two time points, the decomposition position depth H of the sediment scouring section and the sedimentation section in the reservoir within the time interval of the two time points is calculated. k , and based on the first time point H k The effective storage capacity of the reservoir below the depth V0 and the second time point H k The effective storage capacity V of the reservoir below the depth, one implementation method for calculating the sediment deposition amount of the reservoir within the time interval can be to calculate the total area S1, S2, ..., S of the reservoir area at the same water level at two time points. n and the second total area S 01 , S 02, ..., S 0n , select S k ≈S 0k And S k-1 >S 0k-1 , S k+1 0k+1 The water level depth at the time of the two time points is used as the decomposition position depth H of the sediment scouring section and the sedimentation section in the reservoir during the time interval between the two time points. k , where k∈(1,2...,n); based on the first time point H k The effective storage capacity of the reservoir below the depth V0 and the second time point H k The effective storage capacity V of the reservoir below the depth is used to calculate the amount of sediment deposition in the reservoir within the time interval. Therefore, the method of determining the decomposition position depth of the sediment scouring section and the sediment deposition section is carried out through the change trend of the total area of ​​the reservoir area in the bird's-eye view, and the calculation formula of the sediment deposition amount is given. The method is simple and accurate.

[0052] Further, based on the first time point H k The effective storage capacity of the reservoir below the depth V0 and the second time point H k The effective storage capacity V of the reservoir below the depth, one implementation method for calculating the sediment deposition amount of the reservoir within the time interval can be, according to the first time point H k Depth below H k , H k+1 , ..., H n , and the corresponding S k , S k+1 , ..., S n , calculate the first time point H k The effective storage capacity of the reservoir below the depth V0; according to the second time point H k Depth below H k , H k+1 , ..., H n , and the corresponding S 0k , S 0k+1 , ..., S 0n , calculate the second time point H k The effective storage capacity V of the reservoir below the depth; the difference between V0 and V is taken as the sediment deposition amount V of the reservoir during the time interval between the two time points s , V s =V0-V.

[0053] Among them, multiple water levels H1, H2, ..., H n The first total area S1, S2, ..., S at the first time point n , the second total area S at the second time point 01 , S 02 , ..., S​0n The decomposition depth H of the sediment scouring section and sedimentation section in the reservoir k The judgment relationship table is shown in Table 2.

[0055]

[0056] The method for determining the amount of sediment accumulation and effective storage capacity of a reservoir in an embodiment of the present invention calculates the scale between the bird's-eye view of the entire reservoir and the entire reservoir; obtains a plurality of bird's-eye views of the entire reservoir at different water levels, and calculates the total area of ​​the reservoir area at different perimeters based on the perimeter and scale of the reservoir area in each bird's-eye view; in the case where the space of the reservoir area is superimposed by a plurality of barrel-shaped bodies, calculates the total effective storage capacity of the reservoir according to a plurality of different water levels and the total area of ​​the reservoir area; calculates the decomposition position depth of the sediment scouring section and the sedimentation section in the reservoir at two time points, and calculates the amount of sediment accumulation in the reservoir at the two time points according to the effective storage capacity of the reservoir below the decomposition position depth at the two time points. Thus, the effective storage capacity and the amount of sediment accumulation can be quickly and accurately calculated through the bird's-eye view of the entire reservoir and the change trend of the total area of ​​the reservoir area in the bird's-eye view, thereby improving the accuracy of the calculation of the amount of sediment accumulation and the effective storage capacity.

[0057] In summary, the present invention only requires conventional high-definition cameras, water level meters and general image analysis software (such as Photoshop), and does not require a large amount of human and material resources for secondary research and development. The cameras and water level meters involved are common devices with low costs, and a large number of cameras and water level meters have been installed in the reservoir area of ​​ordinary intelligent hydropower plants. The present invention can use existing devices to realize the analysis of reservoir silt accumulation and effective storage capacity without the need to purchase new devices. At the same time, the accuracy of silt accumulation and effective storage capacity is high and easy to operate: the reservoir area can be read directly from the picture with high accuracy. Only ordinary picture analysis software and simple conversion are required, and it is easy to operate.
