Image processing-based high-tension line identification method

Abstract

The invention discloses an image processing-based high-tension line identification method, which connects a high-tension line in target echo points detected by radar in a mode of image processing, and belongs to the field of high-tension line identification and detection. The method comprises the following steps: taking a radar plot map as input; performing primary plot condensation; performing pro-domain analysis on condensed plots; grading each plot; judging high-tension line towers according to the grades; classifying the mutually adjacent high-tension line towers; searching a high-tension line tower chain; extending the high-tension line tower chain in a cranio-caudal direction in all plots, and performing inter-frame voting; and displaying an obtained power line distribution area. By using the method, the positions of the high-tension line towers are judged according to the distribution characteristics of the high-tension line towers; a continuous high-tension line is searched so that a high-tension line distribution area is determined; the method has low requirement on radar resolution and by using the method, a target can be detected at a long distance (beyond 1.5 km); and because only the plots are processed, the method has the characteristics of high efficiency, small computation amount, and positive and great practical value.

Description

technical field [0001] The high-voltage line identification method based on image processing, through image processing, extracts the echo point corresponding to the high-voltage iron tower from the target echo point detected by radar, and connects the high-voltage line, which belongs to the field of high-voltage line identification and detection. Background technique [0002] Aiming at the current problem that helicopters and other low-altitude aircraft are prone to crash accidents due to high-altitude power line collisions when flying at low altitudes, the invention proposes a method for long-distance detection and perception of high-voltage lines using the distribution characteristics of echo points of high-voltage line towers. [0003] The following articles and patent documents basically cover the main background technologies in this field. In order to explain the development process of the technology, let them be arranged in chronological order, and introduce the main c...

Problems solved by technology

[0012] Through the summary and comparison of the existing technologies for detecting high-voltage lines, it can be seen that the existing helicopter collision avoidance equipment is mainly divided into the following directions: using infrared imagers to detect targets, this type of equipment is too affected by the climate, and the operating distance is too large near; use the laser anti-collision radar to detect the target, but the better application condition of the laser anti-collision radar is at night, the sun rays are easy to interfere when working in the daytime, and the combat capability will be reduced under severe weather conditions; the use of millimeter-wave radar to detect The target, detection range and anti-jamming ability have all been improved, about 1.5-3km, and the technical requirements are relatively high
