dcm's Introduction

DCM

这个工程是基于starlino的DCM在matlab上的实现,为了更好在理解DCM算法的实现,感谢dcm_tutorial评论区83楼Leonardo Garberoglio的原有想法。

其中imh.h为原c语言实现,飞行数据来源为sd卡,通过MP地面站转换,如下。

log2matlab

##怎么运行

  1. 将DCM目录作为你的工作目录。
  2. 运行test_dcm命令即可。
  3. 通过修改ACC_WEIGHT加速度计的权重和MAG_WEIGHT磁力计的权重可以看到不同的姿态效果。

##效果分析 在MP地面站,可以对SD卡里在飞行数据进行图形分析,能看出飞控端DCM姿态解算的效果,如下:

sd_dcm 然后根据这个去对比matlab解算的姿态效果,初略的如下:

first_dcm

改进版,在matlab里加入了飞控端的姿态效果:

second_dcm
