Camera FOV & Calibration

Two camera tools: work out field of view and imaged coverage for a lens/sensor combo, or generate a print-accurate calibration pattern for OpenCV/ROS camera calibration.

FOV Calculator

Compute horizontal/vertical/diagonal field of view and imaged coverage at a working distance from sensor size and focal length.

Calibration Patterns

Generate a print-accurate checkerboard or circle-grid calibration pattern, plus why RGB and depth images from RGB-D cameras don't line up.
