在GNSS-IMU的系统里,GNSS往往提供一个低频的定位信息(1-20hz),而IMU会提供一个高频的加速度、角速度信息(200hz左右)。本文的开源代码地址:https://gitee.com/dawanzi98/gnss_imu_odom_at_imu_rate 首先,来回顾eskf的相关理论知识: 1 ESKF 理论回顾 网络上很多文章都对ESKF有深入的介绍,因此在这里,我们仅进行...

In view of this, GNSS and IMU fusion is used outdoors for Error-State Kalman Filter (ESKF) filtering for positioning. At the same time, this paper proposes a D-CEP algorithm to analyze the UWB ranging variance offline and improve the accuracy of UWB positioning data. In the mixed scene, ...
GNSS/INS松组合,曾广了陀螺仪加速度计的零偏、比例因子、交轴耦合误差,而且误差状态向量可以任意增减,最低9维,最高33维。如果你觉得好的话不妨点个赞吧。 最近更新: 10个月前 7 丸子/gnss_imu_odom_at_imu_rate 基于ESKF实现IMU频率的GNSS_IMU融合算法 最近更新: 1年多前 631 Generalized_Aviation/...
