摘要
机器人是新质生产力的革命性引擎,正在重塑人类的生活和工作。同步定位与建图技术(Simultaneous Localization And Mapping,SLAM)能够使机器人在未知环境中自主导航并构建周围环境的地图,是自主移动机器人实现智能化的基石。然而,SLAM算法复杂且运算量大,基于通用芯片方案实现存在延时长、功耗高的问题,不能满足自主移动机器人,尤其是小型、微型、纳型机器人的实时性、体积和功耗需求。因此,设计专用芯片加速计算密集的SLAM算法在近年来受到学术界和产业界的高度关注。本文首先从SLAM技术的基本概念和应用场景出发介绍了SLAM算法需要硬件加速的必要性,接着从算法和专用芯片设计两个角度出发梳理了SLAM技术的研究现状与发展趋势,接着重点讨论了SLAM专用芯片研究的技术挑战与解决方案,对未来发展给出了建议。
Robots represent a revolutionary engine of new productive forces,reshaping human life and work.Simultaneous Localization And Mapping(SLAM)technology enables robots to navigate autonomously in unknown environments and construct maps of their surroundings,serving as the cornerstone for the intelligence of autonomous mobile robots.However,given that SLAM algorithms are complex and computationally intensive,implementations based on general-purpose CPU chips suffer from long delays and high power consumption,which fails to meet the real-time and power consumption requirements of autonomous mobile robots,especially small,micro,and nano ones.Consequently,the design of specialized hardware accelerator chips to accelerate computation-intensive SLAM algorithms has received considerable attention from both the academic and industrial communities in recent years.This article starts with the basic concepts and application scenarios of SLAM technology,and highlights the necessity of hardware acceleration for SLAM algorithms.It then reviews the current research status and development trends from the perspectives of algorithms and dedicated chip design,and discusses the technical challenges and solutions related to SLAM dedicated chips,providing recommendions for future development.
