Requirement Evaluation of CAV Location Performance and Platform Development (RECAPD)

定位和感知是互联自动车辆(CAV)的两个重要组成部分。当驾驶环境因恶劣天气条件而改变时，使用激光雷达、相机和雷达的传感技术存在局限性。利用GNSS、航位推算的大众市场定位技术目前无法满足CAV定位的精度、可用性、稳健性等性能要求。RECAPD将专注于研发负担得起的新位置解决方案，通过使用定义的CAV位置参数作为主要指标来识别英国混合道路上的位置问题。一种能够提供高速率厘米定位精度的先进测量工具将被用来产生“地面真实”轨迹，以评估潜在CAV位置传感器的不同组合的性能。将开发一个新的CAV定位平台，该平台配备了最新的处理引擎，能够根据CAV环境在不同的定位方案之间进行智能切换。它将利用现有的国家地理空间基础设施、全球导航卫星系统载波信号、惯性数据、嵌入式低成本信标等，提供无处不在的定位解决方案。该财团还将与RECAPD最终用户合作，寻找其市场机会。

Location and sensing are two important components for Connected and Autonomous Vehicles (CAVs). Sensing techniques using LiDAR, camera, radar have limitations when driving environments change due to bad weather conditions. The mass-market location techniques utilising GNSS, dead reckoning are currently unable to meet the required CAV location performance such as accuracy, availability, robustness. RECAPD will focus on the R&D of affordable new location solutions through identification of location issues on a mix of UK roads using defined CAV location parameters as major indicators. An advanced survey vehicle capable of delivering high-rate centimetre positioning accuracy will be utilised to produce "ground truth" trajectories for assessing the performance of different combinations of potential CAV location sensors. A new CAV location platform that is empowered with the latest processing engine capable of smartly switching among different location solutions according to CAV environments will be developed. It will use the existing national geospatial infrastructure, GNSS carrier-phase signals, inertial data, embedded low-cost beacons (RFID), etc., for the provision of a ubiquitous location solution. The consortium will also work with RECAPD end users for its market opportunities.
