摘要:

无人驾驶飞行器(UAV)是各种信息收集应用的首选平台。当与更高层级的信息性路径规划算法结合时,传感器规划可以提高这类任务的效率和成功率。本文旨在通过开发一种用于单轴云台的信息性非近视传感器规划框架,并与信息性路径规划器耦合,以最大化先验信息图上的信息增益,从而解决这些数据采集挑战。这是通过在规划时域内找到缩减的传感器扫描边界来实现的,从而使置信度较高的区域得到优先处理。这一新颖的传感器规划框架与预定义传感器扫描和无传感器规划基线进行了评估,并在两个仿真环境中进行了验证。在我们的结果中,我们观察到相对于无传感器规划和预定义传感器扫描基线,性能分别提高了21.88%和13.34%。

英文摘要:

Uncrewed Aerial Vehicles (UAVs) are a leading choice of platforms for a variety of information-gathering applications. Sensor planning can enhance the efficiency and success of these types of missions when coupled with a higher-level informative path-planning algorithm. This paper aims to address these data acquisition challenges by developing an informative non-myopic sensor planning framework for a single-axis gimbal coupled with an informative path planner to maximize information gain over a prior information map. This is done by finding reduced sensor sweep bounds over a planning horizon such that regions of higher confidence are prioritized. This novel sensor planning framework is evaluated against a predefined sensor sweep and no sensor planning baselines as well as validated in two simulation environments. In our results, we observe an improvement in the performance by 21.88% and 13.34% for the no sensor planning and predefined sensor sweep baselines respectively.
