论文摘要
在自主移动平台的各种和动态室内环境中导航仍然是一项复杂的任务。尤其是当条件恶化时,典型的传感器方式可能无法最佳地运行,随后为安全导航控制提供了INAPT输入。在这项研究中,我们提出了一种使用分层控制系统的移动平台进行动态室内环境导航的方法。这些传感器可以在雨,雾,灰尘或污垢等条件下运行。不同的控制层,例如避免碰撞和行为后的走廊,根据声流图像的融合中的声流队列被激活。这项工作的新颖性使这些传感器可以自由放置在移动平台上,并提供了基于移动平台周围分区系统设计最佳导航结果的框架。本文介绍的是使用的声流模型以及分层控制器的设计。在模拟中的验证之后,在真实的办公环境中使用具有一个,两个或三个声纳传感器的实际移动平台在真实的Office环境中进行了实现和验证,并通过2D导航实时实时。在模拟和实际实验中均已验证了多个传感器布局,以证明控制器和传感器融合的模块化方法最佳起作用。这项工作的结果显示了具有动态对象的室内环境的稳定且安全的导航。
Navigation in varied and dynamic indoor environments remains a complex task for autonomous mobile platforms. Especially when conditions worsen, typical sensor modalities may fail to operate optimally and subsequently provide inapt input for safe navigation control. In this study, we present an approach for the navigation of a dynamic indoor environment with a mobile platform with a single or several sonar sensors using a layered control system. These sensors can operate in conditions such as rain, fog, dust, or dirt. The different control layers, such as collision avoidance and corridor following behavior, are activated based on acoustic flow queues in the fusion of the sonar images. The novelty of this work is allowing these sensors to be freely positioned on the mobile platform and providing the framework for designing the optimal navigational outcome based on a zoning system around the mobile platform. Presented in this paper is the acoustic flow model used, as well as the design of the layered controller. Next to validation in simulation, an implementation is presented and validated in a real office environment using a real mobile platform with one, two, or three sonar sensors in real time with 2D navigation. Multiple sensor layouts were validated in both the simulation and real experiments to demonstrate that the modular approach for the controller and sensor fusion works optimally. The results of this work show stable and safe navigation of indoor environments with dynamic objects.
