Issues in computing the length of the trajectory

[ZuoJiaxing]

The function to compute the length of the trajectory is wrong:

open_vins/ov_eval/src/utils/Loader.cpp

Line 256 in 4e0bd81

double Loader::get_total_length(const std::vector<Eigen::Matrix<double,7,1>> &poses) {

The norm of the quaternion should be one, so this should be fine if as is.
It should probably be changed to explicitly norm just the position component for clarity.
Is this the issue that you are referring to?

The norm of the difference of two quaternions is not still restrained to be one. Fixed in the latest commit. Reopen if this was not the issue. We would appreciate it if you provide more details of the error in the future, thanks!
