Obstacle detection system to avoid airborne high-voltage line based on Infrared Technology can effectively guar-antee the safety of low-flying helicopters under low visibility conditions .It avoids low-flying helicopter hit power lines . Having analyzed the principle of infrared imaging ,the author has designed the infrared light path system and digital signal processing system and combined with the Hough transform algorithm to achieve a high-voltage lines detection and alarm . The experiment in the flight demonstration show that the system can effectively identify high-voltage lines within the range of 500 meters of diameter 30~50mm .and can avoid losses due to power lines for the helicopter .It confirmed the validity of the system .
