摘要:

移动和腿式机器人技术的不断成熟正在改变机器人部署和发现的环境。这一创新要求对同时定位与地图构建(SLAM)系统进行转型,以支持新一代服务和消费机器人。传统上强大的2D激光雷达系统不再占主导地位,而机器人正在部署在多层室内,室外非结构化和城市领域,具有越来越便宜的立体声和RGB-D相机。Visual SLAM(VSLAM)系统几十年来一直是研究的主题,少数公开可用的实现已经脱颖而出:ORB-SLAM 3,OpenVSLAM和RTABMap。本文提出了一个比较这3个现代的,功能丰富的,独特的强大的VSLAM技术,还没有对彼此进行基准测试,使用几个不同的数据集跨越多个域的服务机器人协商。ORB-SLAM 3和OpenVSLAM都没有与文献中的至少一个数据集进行比较,我们通过这个镜头提供了见解。该分析旨在寻找通用、功能完整和多域VSLAM选项,以支持广泛的机器人应用,从而集成到新的和改进的ROS 2 Nav 2系统中,作为传统2D激光雷达解决方案的合适替代方案。

英文摘要:

Advancing maturity in mobile and legged robotics technologies is changing the landscapes where robots are being deployed and found. This innovation calls for a transformation in simultaneous localization and mapping (SLAM) systems to support this new generation of service and consumer robots. No longer can traditionally robust 2D lidar systems dominate while robots are being deployed in multi-story indoor, outdoor unstructured, and urban domains with increasingly inexpensive stereo and RGB-D cameras. Visual SLAM (VSLAM) systems have been a topic of study for decades and a small number of openly available implementations have stood out: ORB-SLAM3, OpenVSLAM and RTABMap. This paper presents a comparison of these 3 modern, feature rich, and uniquely robust VSLAM techniques that have yet to be benchmarked against each other, using several different datasets spanning multiple domains negotiated by service robots. ORB-SLAM3 and OpenVSLAM each were not compared against at least one of these datasets previously in literature and we provide insight through this lens. This analysis is motivated to find general purpose, feature complete, and multi-domain VSLAM options to support a broad class of robot applications for integration into the new and improved ROS 2 Nav2 System as suitable alternatives to traditional 2D lidar solutions.
