“…In this work, a dynamic monocular camera is employed to estimate the position and velocity of a moving target. Compared to the multi-camera system [20], using a monocular camera has the advantage of reducing power consumption and the quantity of image data. A You-Only-Look-Once (YOLO) deep neural network [21] is applied in this work for target detection, arXiv:1906.02573v1 [cs.SY] 6 Jun 2019 which relaxes the assumption of continuous availability of the feature point and minimizes the gap for applications, but it also introduces some challenges.…”

An image-based control strategy along with estimation of target motion is developed to track dynamic targets without motion constraints. To the best of our knowledge, this is the first work that utilizes a bounding box as image features for tracking control and estimation of dynamic target without motion constraint. The features generated from a You-Only-Look-Once (YOLO) deep neural network can relax the assumption of continuous availability of the feature points in most literature and minimize the gap for applications. The challenges are that the motion pattern of the target is unknown and modeling its dynamics is infeasible. To resolve these issues, the dynamics of the target is modeled by a constant-velocity model and is employed as a process model in the Unscented Kalman Filter (UKF), but process noise is uncertain and sensitive to system instability. To ensure convergence of the estimate error, the noise covariance matrix is estimated according to history data within a moving window. The estimated motion from the UKF is implemented as a feedforward term in the developed controller, so that tracking performance is enhanced. Simulations are demonstrated to verify the efficacy of the developed estimator and controller.
