Trajectory create from IMU data only

[higash1]

I'm trying to get the initial poses with the correct poses and create trajectory from the velocity and angular velocity information.

I don't know the car's own velocity and angular velocity in dataformat.txt.

And, I thought the car's own velocities were vf,vl and vu but the vf in them was negative even in the picture that should be moving forward.

thank you for this work of yours
