Calculate visual transect width from camera pitch, altitude, and zoom level.

Description

Calculate visual transect width from camera pitch, altitude, and zoom level.

Usage

calc_width(pitch, altitude, ROV = "HDHV", z = 0.06, max.sr = 6)

Arguments

pitch	Camera pitch in degrees (positive or negative; zero equals horizontal).
altitude	Raw altitude from the altimeter or similar device.
ROV	ROV on which camera is installed.
z	Analog voltage output from camera zoom indicator.
max.sr	Maximum slant range or viewing distance in meters.

Value

A data frame containing the camera_altitude, slant_range, and center_width in meters.
