Abstract

The invention discloses a high-voltage line detection method combining deep semantic segmentation with Hough transform, and the method employs a deep learning semantic segmentation technology to makethreshold judgment of a target through combining with the Hough transform, achieves high-performance detection of a high-voltage line, can achieve further confirmation of a detection target through the threshold after the Hough transform, and improves detection accuracy. The false target of an original image is suppressed, and the dual effects of target detection and false alarm reduction are achieved. According to the technical scheme disclosed by the invention, an algorithm flow is concise, detection rate is higher than that of a traditional parameter adjustment method, the false alarm rateis further reduced through Hough transform, and the problem of excessive false alarms of the high-voltage line caused by semantic segmentation is avoided.

Description

technical field [0001] The invention relates to the technical field of radar detection, in particular to a high-voltage line detection method combining deep semantic segmentation and Hough transform. Background technique [0002] The biggest threat to helicopters flying at low altitudes is high-voltage power lines, with which many helicopters have been reported to have collided with high-voltage power lines. Because the helicopter is fast, heavy, and difficult to turn, the helicopter needs a long warning time and braking distance to avoid the high-voltage line. Relative to other objects, high-voltage lines are small and difficult to find from long distances with visual or optical devices. The existing technology mostly uses laser and infrared sensors to detect high-voltage lines, but the detection distance of these two methods is limited, and they are easily disturbed by the weather.

AI Technical Summary

Problems solved by technology

Compared with other objects, high-voltage lines are small in size, and it is difficult to find them from a long distance with vision or optical equipment

Existing technologies mostly use laser and infrared sensors to detect high-voltage lines, but the detection distance of these two methods is limited, and they are easily interfered by the weather

[0003] The echo of power lines such as high-voltage lines has Bragg scattering characteristics, and conventional constant false alarm detection technology cannot achieve good results in detecting high-voltage lines

Especially for the situation that needs to detect high-voltage lines at a longer distance, the detection ability of the existing technology will be greatly reduced, and too many false alarms will be generated
