Great catch! Apparently our documentation is wrong 😅
They are both right. Often the x and y components of the focal length can differ due to a number of reasons; eg from http://ksimek.github.io/2013/08/13/intrinsic/
- Flaws in the digital camera sensor.
- The image has been non-uniformly scaled in post-processing.
- The camera's lens introduces unintentional distortion.
- The camera uses an anamorphic format, where the lens compresses a widescreen scene into a standard-sized sensor.
- Errors in camera calibration.
I'll be very thankful if you submit a PR correcting the documentation.
Hey, I have a question about cameras.h5. Each camera seems to have 2 focal lengths (shape 2x1). All other entries seem to make sense to me (translation is a 3x1, rotation matrix is a 3x3x1, etc). Which is the right value or is there something I am missing?
