Camera Calibration / Appropriate focal lengths
« on: August 25, 2014, 08:32:50 PM »

New user here. I'm working with images taken at different focal lengths of a static subject. Perspectives are generally orthographic but also include skewed angles. Needless to say focal lengths range. Do I need to create  calibration 'files' for each focal length I am dealing with?

Also, what is the recommended number of images to use for creating calibration files? I've typically used four. Will that suffice for rendering 3-D meshes of subjects that cover an area of about 1-2 m?

Thank you for any replies!
