calc_relative_radius

Convert zenith angles (degrees) to normalized radial distance using the lens
projection model.

Tools for preprocessing and processing canopy photographs with
support for raw data reading. Provides methods to address variability in
sky brightness and to mitigate errors from image acquisition in
non-diffuse light. Works with all types of fish-eye lenses, and some
methods also apply to conventional lenses.
