直升机防撞激光雷达综合信息处理系统

设计了一种新型直升机载防撞激光雷达综合信息处理系统。通过对直升机姿态信息的捕获和修正、目标提取与识别、数据三维空间转换等技术,设计并实现了直升机载激光雷达的改进综合信息处理及显示,并且采用扫描成像激光雷达的探测试验对以上技术进行了实际验证。试验结果表明：该系统有效减小了直升机机动飞行时激光雷达探测画面的畸变,在横滚角30°时仍可有效修正探测图像;另外,在600 m处完成了对电力线等不易观察高危目标的迅速提取;实现了探测画面的三维综合高效显示,综合处理时间〈10 ms。本文提出的新的直升机载激光雷达综合信息处理方式有效改良了人机界面。

Comprehensive information processing system of helicopter anticollision laser radar

This article introduces a new comprehensive information processing system for the helicopter anticollision laser radar.Based on the acquirement and correction of helicopter attitude,extraction and identification of a target,and the three-dimensional transformation of data,the processing and display abilities of the system for comprehensive information are improved.Detection experiments of the scan imaging laser radar are designed to verify the effects of these methods.The experimental results indicate that the distortion of detection image is reduced effectively when the helicopter flies for emergency.Even though the roll angle is up to 30°,the correction is still effective.The high-risk targets such as a power line are extracted quickly at the distance of 600 m.Furthermore,the three-dimensional high efficiency integrated display becomes true,and the time of comprehensive processing is less than 10 ms.The new methods of comprehensive information processing of the helicopter anticollision laser radar improves the man-machine interface greatly.
