I have meet some problems while attempting to using my own vdieo to preview the results

I cant analysis how do this happend ，I thought it may reason about the videos，but i have try the sample videos and still get the same results.. @...@

It happend when i enter

from Pose2Sim import Pose2Sim Pose2Sim.triangulation()

[ESJIAN]

logs.txt Calib_scene.txt

here are relative files

Hello, I came across your post and I'm replying because this is an issue I've experienced as well. Sometimes, I faced this issue due to following

1. Not match between calibration result and pose data.
2. Calibration result is too bad.
3. Pose data(json) is incorrect.

And I saw your logs.txt and I think this issue from calibration result which is too high reprojection error😢 Also, correlation for camera sync was 0 it is not normal.

Could you confirm that the data you used for calibration and the pose data (JSON) file are correct?

I agree, I think your calibration is not good enough. Did you edit Config.toml with the coordinates of objects in your scene?

[ESJIAN]

Just as you said,Calibration result is too bad. camera sync was 0 and it might has relationship with Calibration result?

I switch to use board to calibrate the extrinsic parameters and it looks OK from the preview.But still get the also error report like below

My purpose is to test the videos from two same cameras, and I try to search the if any others try this project on CN Internet but none...（T ... T） I will keep trying！

[ESJIAN]

Oh, I wonder what files I should upload to give you to analysis the question

[davidpagnon]

It is definitely possible, even if it is not ideal, to use 2 single cameras. Can you send the preview of the extrinsic calibration images?

You may also have an issue with synchronization, it is sometimes good to play with the parameters in the Config file to get good results (or to synchronize by hand)

The synchronization would be performed with only pose data. So, It is not related to the calibration result!
