Abstract

Abstract

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.
