Research on Augmented Reality Technology of Helicopter Aided Navigation Based on Lidar

Helicopters are widely used due to their excellent low-altitude flight characteristics and convenient take-off and landing advantages. However, the complex environment in low altitude has always been a high-risk scenario where helicopter accidents frequently occur. Lidar has become a key sensor for future helicopters to improve their survivability due to their three-dimensional sensing capabilities, full-time detection, and high accuracy. This article first introduces the laser radar-based helicopter-assisted navigation augmented reality processing framework, and then discusses the laser radar point cloud data processing method in detail. Finally, the point cloud data and the image are superimposed and fused to achieve the effect of augmented reality. The verification in the simulation environment shows that the augmented reality effect brought by the superposition and fusion of the processed point cloud data and the image can effectively improve the pilot's environmental perception ability.
