几种slam算法的轨迹都与轨迹真值有个偏差,使用evo里面的轨迹处理工具,尝试矫正了一下,算出来的rmse偏差还是很大,想请问您是如何对齐轨迹与轨迹真值的呢?

Image这个图是fastlivo在eee03 使用evo_ape tum output_eee03.txt eee03_fastlivo2.txt -va --plot --plot_mode xyz --align_origin 对齐的结果,偏差还是很大。

你没考虑leica和imu之间的外参,我记得那个外参有几十cm,按照官方的评估方法来 https://ntu-aris.github.io/ntu_viral_dataset/evaluation_tutorial.html#evaluate_onem
