Problems solved by technology
The traditional manual inspection method not only takes a long time and is slow, but also the accuracy of the inspection, the timeliness of the safety hazard alarm, and the safety of the inspection personnel are difficult to guarantee.
In recent years, machine vision, or target detection solutions, are easily affected by weather or occlusions, making its accuracy and timeliness not guaranteed

Embodiment Construction
[0030] The present invention will be further described below in conjunction with specific examples.
[0031] Such as figure 1 As shown, the target tracking algorithm-based foreign object detection method for high-voltage transmission lines provided by this embodiment is as follows:
[0032] 1) Install cameras slightly lower than the high-voltage transmission line on the transmission towers at both ends of the high-voltage transmission line. Adjust the angle of the camera so that the camera can be aimed at the high-voltage power line with a bird's-eye view. At the same time, ensure that the background in the camera is as simple as possible, and there are no other objects at the edge. For the same high-voltage transmission line, cameras need to be installed on the transmission towers at both ends of the line, so that the same high-voltage transmission line can be captured by at least two cameras at the same time, and the target can be tracked and monitored from multiple angles...

The invention discloses a high-voltage power transmission line foreign matter detection method based on a target tracking algorithm. The method comprises the following steps: placing a camera device on a power transmission tower and transmitting data; collecting and marking foreign matters of the high-voltage transmission line; training a yolov5 model , and performing optimization; performing Hough straight line detection on the detection range to obtain an approximate range of the high-voltage transmission line; detecting the video stream, optimizing a detection result by using a soft-nm algorithm, and selecting a target to be tracked; based on a DeepSort target tracking algorithm, using Kalman filtering to predict the position of a tracking target; using a Hungary algorithm to solve the correlation degree of the prediction target and the detection target, and performing matching; according to an existing tracking target trajectory, obtaining whether the tracking target can reach a high-voltage transmission line area ; and according to the final position of the tracking target, determining whether the tracking target is an abnormal target influencing the high-voltage transmission line. According to the method, the foreign matters approaching and adhering to the power transmission line can be timely and accurately detected, and an alarm can be quickly given out.
Description
technical field [0001] The invention relates to the technical field of intelligent monitoring of power systems, in particular to a method for detecting foreign objects in high-voltage transmission lines based on a target tracking algorithm, which can be applied to monitor foreign objects approaching high-voltage transmission lines and issue an alarm in time. Background technique [0002] The power system occupies an increasingly important position in the current social life and development. The transmission line is responsible for connecting power plants, substations and users, and plays an irreplaceable role as a link. The guarantee of its safety and stability is very important. In order to reduce the energy loss in the transmission process, high-voltage transmission is often used. However, because most of the high-voltage transmission lines are located in mountains and hilly terrain, and the span is very large, it is very difficult to detect and maintain. It is even more...
