About focal_length=5000 #46

Thanks for your brilliant work! I notice that you estimate the camera parameters by using a function called "estimate_translation_np" (borrowed from SPIN). I feel puzzled that why you could set the same focal length (5000) for different datasets and different images. Thanks again and hope for your reply.

Hi, The focal length of 5000 is indeed not accurate. There are papers trying to tackle this problem:
