摘 要: | 基于红外技术的机载高压线避障系统能有效保证直升机在低能见度条件下的低空飞行安全,避免直升机低空飞行撞击高压线。在分析红外成像原理的基础上,设计了红外光路系统和数字信号处理系统,结合霍夫变换算法,实现了高压线辨识与报警。该系统在某型直升机上挂载飞行表明:系统能较好地辨识500m范围内直径30~50mm的高压线,有效避免因高压线造成的直升机损失。

Abstract: | 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 . |
