calc_AFOV: Calculates the Angular Field of View

In ailich/mytools: Stuff

Calculates the Angular Field of View

Description

Calculates the angular field of view (in degrees) based on camera and lens properties. Can calculate horizontal, vertical, and diagonal angular field of view in either air or seawater. If d is unknown, it can be approximated by pix and pixel_size. If d is known, either aspect_ratio or pix can be used.

Usage

calc_AFOV(
  d = NULL,
  f = NULL,
  medium,
  type,
  pix = NULL,
  aspect_ratio = NULL,
  pixel_size,
  n_air = 1.000277,
  n_sea = 4/3
)

Arguments

d	length of diagonal of camera sensor (must be same units as f)
f	focal length of lens (must be same units as d or pixel size)
medium	"air" or "seawater"
type	Type of field of view. Either "horiz", "vert", or "diag" (diag does not need pix or aspect ratio)
pix	width and height of frame in number of pixels c(width, height)
aspect_ratio	aspect ratio e.g. c(16,9)
pixel_size	pixel size of camera sensor (must be same units as f)
n_air	index of refraction for air (default = 1.000277)
n_sea	index of refraction for seawater (default = 4/3)
