How to get extrinsic #84

Closed terry-r123 closed 2 years ago

Hi, @zokin @vladsterz Thank you for your exciting work!

I would like to know when I only have run calibration.py with my own.pgm and .png files of multiple cameras and got the calibration.json, how I select the main camera, and how to get extrinsic of other cameras relative to the main camera

such as: image

I would like to know how to get the external reference of camera k4a2982 with respect to camera k4a3495

Thanks!!!

Hi @terry-r123 ,

Unfortunately this information is not captured by the system. Every camera is registered individually.

Thanks, @ankarako . Can I make cameras horizontally to calibrate, because we want to shoot video horizontally to widen the field of view

Unfortunately (again), this would not be possible, because we use an AI calibration procedure, and the neural network is trained on vertical views, as this was our use case.
