CameraTransform: a Scientific Python Package for Perspective Camera Corrections

Scientific applications often require an exact reconstruction of object positions and distances
from digital images. Therefore, the images need to be corrected for perspective distortions.
We present CameraTransform, a python package that performs a perspective image
correction whereby the height, tilt/roll angle and heading of the camera can be automatically
obtained from the images if additional information such as GPS coordinates or object sizes are
provided. We present examples of images of penguin colonies that are recorded with stationary
cameras and from a helicopter.
