Design and research of intelligent vehicle strapdown line-of-sight stabilization platform system

Based on the features of environment perception system for intelligent vehicle, a strapdown line-of-sight stabilization platform system is designed, which used to isolate the line-of-sight of perception sensors mounted on the intelligent vehicle from the vehicle body angle movement. The mechanical structure, servomechanism and strapdown stabilization algorithm are elaborated in detail. To validate the stable tracking performance of platform system whether it could meet the operating requirements, a test for line-of-sight stable tracking of perception sensors was designed. And results indicated that vehicle-borne strapdown line-of-sight stabilization platform design satisfies application requirements of perception sensors mounted on the inner gimbal of platform on the intelligent vehicle.
