R_nm_nm_1的计算问题 #29
Comments
我看了一下,第二个转置应该要去掉。 eskf-gps-imu-fusion/src/eskf.cpp Line 150 in da93afa
这个转置去掉: eskf-gps-imu-fusion/src/eskf.cpp Line 210 in da93afa
你看一下这样改之后,是不是就是对的了。这一块内容时间有点儿久了,公式我记得不是很清晰,得翻书重新推导验证一遍。 |
感觉你这样改是对的,w_in是时刻 m-1 -> m 地球转动引起的导航系转动角速度,而姿态更新公式如果写成: |
eskf.cpp(当前主分支150行),计算R_nm_nm_1时,用angle_axisd对应的旋转矩阵的transpose,210行在使用R_nm_nm_1时,又transpose了一下,这是误操作?还是姿态解算方程使然?
