Abstract:This paper proposes an approach of target tracking of a ground target for UAVs using Optimal Two-Stage Cubature Kalman Filter and Improved Coordinated Lateral Guidance Law. Firstly, the Optimal Two-Stage Cubature Kalman Filter (OTSCKF) is proposed to estimate the target motion. The OTSCKF combines two-stage filtering technology with CKF to improve the estimation accuracy. Secondly, to keep a constant distance between the UAV and the target, a new guidance law based on the lateral turning equation is proposed a… Show more
“…However, because a UAV must fly at a high height in order to obtain a broad observation view, the objects that are photographed frequently have a small pixel size, and the categories that they fall into are subject to a great deal of ambiguity. Many advanced computer vision applications rely on visual image detection, including autonomous driving, face identification and recognition, and activity recognition [ 3 ]. Significant improvement has been made in recent years, but these algorithms prioritize detection in generic circumstances above those taken by drones.…”
