摘要:

传感器融合算法的精度受到两类因素的限制:传感器固有噪声,或传感器时间同步的质量。固有传感器噪声仅取决于相应的传感器本身,而由同步质量或同步缺失所引起的误差,则取决于车辆和机器人系统的动力学特性以及时间同步误差的大小。为满足传感器融合需求,系统设计者不仅必须考虑使用何种传感器,还必须考虑如何对这些传感器进行同步。本文提出了 Syncline 模型,这是一个简单直观的可视化模型,用于说明时间同步如何影响不同移动机器人平台的传感器融合精度。该模型可作为一种简单工具,用于确定应当采用哪些同步机制。

英文摘要:

The accuracy of sensor fusion algorithms are limited by either the intrinsic sensor noise, or by the quality of time synchronization of the sensors. While the intrinsic sensor noise only depends on the respective sensors, the error induced by quality of, or lack of, synchronization depends on the dynamics of the vehicles and robotic system and the magnitude of time synchronization errors. To meet their sensor fusion requirements, system designers must consider both which sensor to use and also how to synchronize them. This paper presents the Syncline model, a simple visual model of how time synchronization affects the accuracy of sensor fusion for different mobile robot platform. The model can serve as a simple tool to determine which synchronization mechanisms should be used.
