This work develops a distributed message-passing approach to cooperative localization for autonomous mobile vehicles that communicate via mm-wave wireless connection in vehicle-to-vehicle networks. Vehicles in the network obtain the measurement information about the relative distance and the angle of arrival from the mm-wave connections made with each other. Some vehicles may obtain knowledge about their absolute position information of different quality, for example, via additional localization feature. The main objective is to estimate the locations of all vehicles using reciprocal exchanges of simple information called a message in a distributed and autonomous way. A simulation is developed to examine the performance of the localization and navigation of vehicles under various network configurations. The results show that it does provide better positioning results in most cases and there are also several cases where the use of the cooperative technique adapts to design parameters such as accuracies of measurement equipment, and initial position estimates, that can affect the localization performance.
这项工作开发了一种分布式消息传递方法,用于在车对车网络中通过毫米波无线连接进行通信的自主移动车辆的协同定位。网络中的车辆从相互建立的毫米波连接中获取有关相对距离和到达角度的测量信息。一些车辆可能通过额外的定位特征等方式获得不同质量的绝对位置信息。主要目标是以分布式和自主的方式,通过称为消息的简单信息的相互交换来估计所有车辆的位置。开发了一个模拟程序来检验在各种网络配置下车辆定位和导航的性能。结果表明,在大多数情况下它确实能提供更好的定位结果,并且在一些情况下,协作技术的使用也能适应诸如测量设备精度和初始位置估计等可能影响定位性能的设计参数。
