视觉SLAM机器人中光束法平差优化芯片研究综述
A survey of bundle adjustment optimization chips in visual SLAM robots
摘要
Abstract
In Visual Simultaneous Localization and Mapping(V-SLAM)systems,Bundle Adjustment(BA)plays a crucial role in opti-mizing camera parameters and the positions of 3D points.However,due to the high computational complexity and real-time require-ments of BA,traditional computing platforms struggle to meet efficiency demands.Recently,the introduction of dedicated hardware ac-celerators has provided new solutions for BA optimization.This paper reviews the current status of research and development trends in BA optimization-specific chips.It covers the application scenarios,definitions,and basic principles of BA algorithms;the acceleration of BA on Field-Programmable Gate Arrays(FPGA),Application-Specific Integrated Circuits(ASIC),and Graphics Processing Units(GPU),as well as the development trends of these accelerators.Furthermore,this paper discusses the technical challenges in imple-menting BA accelerators and anticipates future development directions.By summarizing current research advancements,this review aims to provide guidance and insights for future studies on BA optimization-specific chips.关键词
