摘要:

四旋翼的日益普及已经产生了一类主要由视觉驱动的车辆。研究了四旋翼飞行器感知时间最优路径参数化问题。虽然有许多不同的感知模式可供选择,但四旋翼系统的低重量和功率预算使相机成为机载导航和估计算法的理想选择。然而,这确实带来了一系列挑战。摄像机有限的视场会限制环境中显著区域的可见性,这就要求有必要联合考虑感知和规划。本文的主要贡献是一个有效的时间最优路径参数化算法的四旋翼有限的视野限制。我们在仿真研究中表明,一个国家的最先进的控制器可以跟踪计划的轨迹,我们验证了所提出的算法在实验中的四旋翼平台。

英文摘要:

The increasing popularity of quadrotors has given rise to a class of predominantly vision-driven vehicles. This paper addresses the problem of perception-aware time optimal path parametrization for quadrotors. Although many different choices of perceptual modalities are available, the low weight and power budgets of quadrotor systems makes a camera ideal for on-board navigation and estimation algorithms. However, this does come with a set of challenges. The limited field of view of the camera can restrict the visibility of salient regions in the environment, which dictates the necessity to consider perception and planning jointly. The main contribution of this paper is an efficient time optimal path parametrization algorithm for quadrotors with limited field of view constraints. We show in a simulation study that a state-of-the-art controller can track planned trajectories, and we validate the proposed algorithm on a quadrotor platform in experiments.
