Description

[0002] At present, a camera is arranged on a tower of a power transmission channel to monitor the situation in the power transmission channel, so as to realize abnormal and hidden danger inspection of the power transmission channel. The field of view of a general camera is wide enough to cover the power transmission channel where the camera is located. Current hidden danger inspection generally alarms all hidden dangers appearing in the field of view of the power transmission channel camera. However, due to the wide field of view of the camera lens, some hidden dangers appear at a position far from the tower and the conductor. The alarm generated based on such hidden dangers is an invalid alarm. Moreover, the wide field of view of the camera lens covers multiple power transmission channels. When the same hidden danger is captured by different cameras, repeated alarms for the same hidden danger will occur. In order to improve the accuracy of the alarm information, an effective alarm conductor protection zone needs to be set to avoid repeated alarms and invalid alarms for hidden dangers appearing in the zone.

Obviously, the described embodiments are some but not all of the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art without creative work fall within the protection scope of the present application.

[0046] It should be noted that, in this document, the terms “comprising” and “including” or any other variant thereof are intended to cover non-exclusive inclusion, so that processes, methods, articles, or devices including a series of elements not only include those elements, but also include other elements not explicitly listed, or further include inherent elements of such processes, methods, articles, or devices. Without more limitations, the element defined by the statement “comprising a” does not exclude the presence of additional identical elements in the process, method, article, or device including the element.

[0047] Embodiment 1

[0048] Reference is made toFigure 1 As shown in the embodiments of the present application, a method for dividing a conductor protection area of a power transmission channel is provided, comprising:

[0049] A camera arranged on a tower is used to collect a power transmission channel image.

[0050] The power transmission channel image is segmented by a pre-trained conductor segmentation model to obtain a segmented conductor mask image; in the specific implementation process, a PointRend segmentation model is trained to obtain the conductor segmentation model.

[0051] The segmented conductor mask image contains line noise similar to the conductor, and the conductor needs to be selected from the conductor mask image; referring to Figure 2 As shown in the embodiments of the present application, the conductor is selected from the conductor mask image, comprising:

[0052] The conductor mask image is subjected to median filtering processing, and the median filtered conductor mask image is subjected to dilation processing; the dilated conductor mask image is subjected to connected component detection, and the connected components with an area smaller than a set area threshold are deleted, and the filtered connected components are selected as the conductor. The selection of the area threshold is based on the pixel of the power transmission channel image and the area occupied by the conductor in the power transmission channel image.

[0053] The left and right conductors of the camera are extracted from the selected conductor, wherein the x-axis coordinate of the lowermost point of the left conductor is greater than the x-axis coordinate of the uppermost point, and the x-axis coordinate of the lowermost point of the right conductor is smaller than the x-axis coordinate of the uppermost point; the non-left and right conductors are deleted; in the camera view arranged on the tower, the conductor monitored by the camera is consistent with the camera view direction, and the distance between the conductors consistent with the camera view direction is close at near distance and wide at far distance, therefore, the x-axis coordinate of the lowermost point of the left conductor of the camera is greater than the x-axis coordinate of the uppermost point, and the x-axis coordinate of the lowermost point of the right conductor of the camera is smaller than the x-axis coordinate of the uppermost point. The non-left and right conductors are deleted to avoid the influence of the power transmission channel image on the division of the conductor protection area.

[0054] A tower detection model is used to identify the tower in the power transmission channel, and the coordinates of the tower detection frame output by the tower detection model are saved; in the specific implementation process, the tower detection model uses a yolo model for identifying a set type of tower, and the tower categories include iron single and double towers and cement single and double towers.

[0055] According to the tower detection frame position, the conductors are filtered to obtain effective conductors, wherein the effective conductors meet at least one of the following conditions: the x-axis coordinate of the uppermost point of the left side conductor is less than the right side boundary of any tower detection frame; the x-axis coordinate of the uppermost point of the right side conductor is greater than the left side boundary of any tower detection frame; the extension line of the left and right side conductors intersects any tower detection frame; after the conductors on the left and right sides of the camera are screened out, the conductors are further screened according to the positional relationship between the conductors and the towers, so as to avoid the influence of the line type in the power transmission channel image that is not associated with the tower.

[0056] The main tower is selected. Generally, the power transmission channel image often contains multiple power transmission channels and multiple towers, and the image collected by the camera at the tower is only used for protection division of the power transmission channel where the tower is located. Therefore, the main tower is selected from the multiple towers to determine the position of the conductor and the tower related to the power transmission channel. Referring to FIGS. 1, 2 and 3, the process of selecting the main tower includes: counting the number of conductors intersecting each tower detection frame, taking the tower with the maximum number of conductors intersecting as the main tower, and if multiple towers have the maximum number of conductors intersecting and are equal, taking the tower with the maximum area of the tower detection frame as the main tower. Figure 3

[0057] The leftmost and rightmost two outermost conductors are selected from the effective conductors matched with the main tower, and the conductor protection area is obtained by projecting the area where the outermost conductors are located.

[0058] After the main tower is determined, it is detected whether the conductor intersects the area of the main tower detection frame after being enlarged by a first set multiple. If yes, the conductor matches the main tower.

[0059] The leftmost and rightmost two outermost conductors are selected from the effective conductors matched with the main tower, and the conductor protection area is obtained by projecting the area where the outermost conductors are located.

[0060] Referring to FIGS. 1, 2 and 3, the leftmost and rightmost two outermost conductors are selected from the effective conductors matched with the main tower, and the conductor protection area is obtained by projecting the area where the outermost conductors are located. Figure 4 Figure 5 The lowermost of the leftmost and rightmost conductors of the main tower is extended in a flush manner, so as to reach at least one tower detection frame boundary.

[0061] The lowermost of the leftmost and rightmost conductors of the main tower is extended in a flush manner, so as to reach at least one tower detection frame boundary.

[0062] ​​The leftmost conductor and the rightmost conductor lowest point is mapped to the tower bottom, the leftmost conductor and the rightmost conductor highest point is projected downward with the tower bottom as the axis of symmetry, and the leftmost conductor and the rightmost conductor lowest point and highest point mapping area is the conductor protection zone; if the conductor protection zone side exceeds the image boundary, the conductor protection zone side is shortened to the image lower boundary, and if it does not reach the image lower boundary, the conductor protection zone side is extended to the image lower boundary according to the slope of the mapped conductor protection zone side.

[0063] During the entire conductor protection zone division process, conductor detection and tower monitoring are the premise of conductor protection zone division. When the following exceptions occur, an exception is thrown and the conductor protection zone is not set:

[0064] The conductor segmentation model does not detect the conductor, and the tower detection model does not detect the tower, such as Figure 6 Conductor detection exception caused by filtering all conductors on one side of the camera, tower detection exception caused by filtering all towers, and conductor and tower mismatch caused by intersection of effective conductors and main towers.

[0065] When the following exceptions occur, an exception is thrown but the conductor protection zone is set:

[0066] The conductor is not in the expanded area after the tower detection box is enlarged by a first set multiple, but is in the expanded area after the tower detection box is enlarged by a second set multiple, an exemplary first set multiple is 1.5 times, and an exemplary second set multiple is 2 times. For example Figure 7 The conductor may be incomplete exception is thrown, but the conductor protection zone is still set.
