Alignment for Non-Constant Time Shift Between 1D Data Sets?

Hi, r/robotics,

I’m facing a problem related to camera calibration because I have two pose sets with a varied time difference.

I’m trying to find an open source package for attacking this problem by brute force solution, so I can find corresponding points in two 1D data sets (derived from raw pose sets) first and solve for AXXB equation after.

I haven’t had any luck to find one so can someone please give me a recommendation?

I’ve tried using correlation it worked but not precise enough as the time difference between two sets is not a constant and varied over time slightly.

Sorry if here is not the right subreddit.
