[0042] To make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be described in detail below. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other implementation methods obtained by ordinary technicians in this field without creative work belong to the scope of protection of the present invention.
[0043] Existing bare wire identification relies on manual labor. Only when the line is out of power can the inspectors climb the pole to count the number of aluminum wire strands on the outer layer of the bare wire, so as to determine the model of the bare wire. Manual climbing the pole to identify with the naked eye can only be performed after the power is cut off. It is not only inefficient and has potential safety hazards, but also causes large-scale power outages in the operating area, affecting production and life. Therefore, the present invention provides a method, system, equipment, medium and program product for identifying the number of aluminum wire strands of power transmission bare conductors. By segmenting the power transmission bare conductor images collected by drones and extracting the number of aluminum wire strands on the outer layer of the bare conductors, the number of aluminum wire strands of the power transmission bare conductors can be efficiently and safely identified. The technical solution of the present invention is described in detail below in conjunction with specific embodiments.
[0044] like Figure 1 As shown, an embodiment of the present invention provides a method for identifying the number of strands of bare aluminum wires of a power transmission conductor, comprising the following steps:
[0045] S1: Acquire the captured image of the bare power transmission wire and perform preprocessing.
[0046] In the specific implementation, the image of the bare power transmission wire is taken by a drone. It should be noted that when the image of the bare power transmission wire is taken by a drone, the drone and the bare wire are in a parallel position, and the bare wire needs to be in a horizontal or vertical direction in the image to facilitate the subsequent segmentation of the bare wire.
[0047] In this embodiment, the preprocessing process includes: extracting a bare wire area from the photographed transmission bare wire image, and intercepting a bare wire image of a preset size from the extracted bare wire area.
[0048] In one or more embodiments, the bare wire area in the photographed bare power transmission wire image is extracted by a watershed algorithm. The principle of the watershed algorithm is as follows:
[0049] The basic idea of the watershed algorithm is to regard the image as a topological landform in geodesy. The gray value of each pixel in the image represents the altitude of the point. Each local minimum and its affected area are called a catchment basin, and the boundary of the catchment basin forms a watershed. The concept and formation of a watershed can be explained by simulating the immersion process: when the water level rises to a certain height, the water will overflow the current valley. A dam can be built on the watershed to avoid the water from the two valleys from converging. In this way, the image is divided into two pixel sets, one is the flooded valley pixel set, and the other is the watershed line pixel set; finally, the lines formed by these dams partition the entire image, thus realizing the image segmentation.
[0050] Specifically in this embodiment, the process of extracting the bare wire area in the photographed transmission bare wire image by using the watershed algorithm is as follows:
[0051] S11: Compare the average grayscale value of the global pixels of the bare power transmission wire image with the minimum grayscale value h min The difference c is used as the threshold;
[0052] S12: Select the minimum gray value h in the image of bare power transmission wire min The pixels of are used as the starting points of the immersion process. These pixels represent the deepest places, and the simulated water expands outward from these points.
[0053] S13: Water level from h min Start to rise gradually and increase gradually until it reaches the maximum grayscale value h max ;Whenever the water level rises, the grayscale value of the pixels in the image of the bare power transmission wire is also taken into account, and as the water level gradually rises, different areas are gradually "flooded";
[0054] S14: If the gray value of a pixel is equal to h at the current water level min If the difference is less than the threshold c, the pixel is considered to belong to the same catchment basin and is classified as a "flooded" area; if the difference is greater than c, the pixel is considered to be located between different catchment basins and is marked as a "watershed boundary", that is, a bare wire boundary, thereby extracting and retaining the bare wire area.
[0055] It should be noted that if the bare wire in the image of the bare power transmission wire taken by the drone is not in a horizontal or vertical direction, the pre-processed image needs to be rotated so that the bare wire is in a horizontal or vertical direction.
[0056] S2: Input the preprocessed transmission bare wire image into the pre-trained bare wire segmentation model to obtain a binary mask image of the outer aluminum wire of the bare wire.
[0057] Specifically, the bare wire segmentation model is obtained by the following method:
[0058] S21: Collect images of bare power transmission wires using drones.
[0059] S22: Annotate the boundary of the outer aluminum wire of the bare wire in the transmission bare wire image, obtain the corresponding mask image, and then construct a sample data set. The process of annotating the boundary of the outer aluminum wire of the bare wire in the transmission bare wire image includes:
[0060] The watershed algorithm is used to segment the transmission bare wire image, and only the bare wire area is retained;
[0061] Cut out a bare wire image of a preset size from the bare wire area;
[0062] The boundaries of each aluminum wire on the outer layer of the bare wire in the intercepted bare wire image are manually marked.
[0063] S23: Perform data enhancement processing on the sample data set to expand the sample data set. Data enhancement processing includes cropping, rotation, color conversion, etc. The enhancement of the sample data set can make the trained model more robust.
[0064] S24: Train the semantic segmentation network based on the sample data set to obtain a bare wire segmentation model.
[0065] In this embodiment, the semantic segmentation network adopts a fully convolutional neural network. During the training process, the stochastic gradient descent method is used for optimization, and the loss function Loss used is:
[0066]
[0067] In the formula, This is the loss of the upsampling part, where M is the total number of upsampling layers, is the weight of the mth upsampling layer, is the loss value of the mth upsampling layer, and the loss of the mth upsampling layer It is calculated based on the difference between the output of layer m and the true label (Ground Truth, GT for short); This is the loss of the final fusion step, where is the weight of the fusion step, It is the loss value of the fusion step, which measures the difference between the probability map finally output by the model and the true label (Ground Truth, GT for short). The fusion step combines the high-level features extracted in the downsampling path with the features in the upsampling path to generate the final segmentation map.
[0068] S3: Perform skeleton extraction on the binary mask image of the outer aluminum wire of the bare conductor to obtain a skeleton image of the outer aluminum wire of the bare conductor.
[0069] In specific implementation, the skeleton extraction method includes but is not limited to the HilditchThin algorithm, the Rosenfeld algorithm, and the thinning algorithm in OpenCV_Contrib.
[0070] S4: Traverse the binary mask image of the outer aluminum wire of the bare conductor to find the vanishing point of the diagonal lines. Specifically include:
[0071] S41: Traverse the binary mask image of the outer aluminum wire of the bare conductor in the column / row direction of the bare conductor length to obtain the pixel point with a pixel value of 1 on the outermost side, and count the number of pixel points with a pixel value of 1 in a 3×3 area centered on the pixel point.
[0072] It should be noted that when the length direction of the bare wire is horizontal, it is traversed column by column from left to right or from right to left, and the pixel point with a pixel value of 1 at the top or at the bottom is selected as the center for pixel point statistics. When the length direction of the bare wire is vertical, it is traversed row by row from top to bottom or from bottom to top, and the pixel point with a pixel value of 1 at the leftmost or at the rightmost is selected as the center for pixel point statistics.
[0073] S42: If the number of pixel points with a pixel value of 1 is 3, it is considered that the point is not a twill vanishing point; if the number of pixel points with a pixel value of 1 is 4, the point is a twill vanishing point.
[0074] like Figure 2 As shown in (a), when the length direction of the bare wire is horizontal, the statistical result is 3. The three pixels are connected in a straight line, and there are no bifurcated pixels, indicating that this is not a twill vanishing point. It should be noted that the situation where there are only three pixels with a pixel value of 1 in the statistical area and they are not located on the same straight line does not exist in the actual process. Therefore, there will be no situation where the statistical result is 3 but there are bifurcated pixels.
[0075] like Figure 2As shown in (b), when the length direction of the bare wire is horizontal, the statistical result is 4, where 3 pixels are connected to form a straight line, and 1 pixel intersects the straight line, and there are bifurcated pixels, indicating that this is the diagonal vanishing point. It should be noted that the situation where there are only 4 pixels with a pixel value of 1 in the statistical area and no 3 pixels are located on the same straight line does not exist in the actual process.
[0076] S5: Draw a vertical line at the twill elimination point in the vertical direction of the length direction of the binary mask image of the outer aluminum wire of the bare conductor, count the number of skeleton lines n that the vertical line passes through, and determine whether the intersection of the vertical line and the other side of the binary mask image of the outer aluminum wire of the bare conductor is the twill vanishing point; if so, the number of strands of the outer aluminum wire of the bare conductor is 2n, if not, the number of strands of the outer aluminum wire of the bare conductor is 2n-1.
[0077] When the number of aluminum wire strands on the outer layer of the bare conductor is an even number, the vanishing points of the diagonal lines on both sides are symmetrical. Therefore, the number of aluminum wire strands on the outer layer of the bare conductor is twice the number of skeleton wires through which the vertical line passes. Figure 3 As shown in (a), the number of skeleton wires that the vertical line passes through is 3, and the actual number of strands of the outer layer of the bare conductor is 6. When the number of strands of the outer layer of the bare conductor is an odd number, the vanishing points of the diagonal lines on both sides are asymmetric. Therefore, the number of strands of the outer layer of the bare conductor is twice the number of skeleton wires that the vertical line passes through. Figure 3 As shown in (b), the number of skeleton wires that the vertical line passes through is 4, which is equivalent to the vertical line passing through 3.5 aluminum wires, and the actual number of aluminum wire strands on the outer layer of the bare conductor is 7.
[0078] The method for identifying the number of aluminum wire strands in a bare power transmission conductor proposed in the above embodiment can directly segment the bare power transmission conductor and identify the number of aluminum wire strands in the outer layer of the bare power transmission conductor using images of the bare power transmission conductor taken by a drone, thereby realizing uninterrupted and contactless bare wire model identification of the transmission line, reducing the risks brought by climbing and power outages, greatly saving manpower, and improving the efficiency of identifying the number of aluminum wire strands in the outer layer of the bare power conductor.

[0080] An image acquisition module is used to acquire the photographed image of the bare power transmission wire and perform preprocessing;

[0082] A skeleton extraction module is used to extract the skeleton of the binary mask image of the outer aluminum wire of the bare conductor to obtain a skeleton image of the outer aluminum wire of the bare conductor;
[0083] The module for extracting the vanishing point of the twill is used to traverse the binary mask image of the outer aluminum wire of the bare conductor to find the vanishing point of the twill;
