static_imu_calib dataset link in imu_intrinsics.md is invalid

[JafarAbdi]

I'm trying to run the example in https://github.com/urbste/OpenImuCameraCalibrator/blob/master/docs/imu_intrinsics.md, but looks like the link for the static_imu_calib dataset is no longer valid.

Hey, you are right I removed it by accident. I would upload a new one but I currently do not have access to my camera. Do you need guidance how to record one on your own?

Thanks for your response!

That would be amazing, thanks!

So in general the procedure and method is described in this paper.

Check Figure 1 of the paper!

You just start recording a video (best to use lowest resolution and FPS setting as the video is not needed).

1. Start recoding and place the camera on the floor
2. Let it stand still for 10 seconds (initial bias estimation)
3. Turn it around to a different side
4. Let it stand still for 4-5 seconds

Repeat 3 and 4 for 10-15 times in different angles and directions. You might also use the corner from floor to wall to make it stand in different inclination angles.

@urbste static_multipose_imu_calibration.py is still referencing javascript implementation for telemetry extraction in master branch where it has been replaced by your py_gpmf python package.
