camera adjuster fails #234

Hi,

Nice and very detailed implementation.

I tried you stitched detailed notebook on our own set of images (no.of images are 3). but it fails with below error

error Traceback (most recent call last)
/tmp/ipykernel_2447557/2344847478.py in

9 cameras = camera_estimator.estimate(features, matches)
---> 10 cameras = camera_adjuster.adjust(features, matches, cameras)
11 cameras = wave_corrector.correct(cameras)

47 if not b:
48 raise StitchingError("Camera parameters adjusting failed.")

error: OpenCV(4.9.0) /io/opencv/modules/calib3d/src/compat_ptsetreg.cpp:125: error: (-215:Assertion failed) !err.empty() in function 'update'

I tried with all the camera adjuster, it works with no but non of other options works. I am not getting correct outuput with no adjuster. Could you please let m know what could be the reason and possible ways to analyse further on this issue.

Thanks,
Veeru.
