Calibrate the camera on the given xy coordinate — cam_cal_pt • radiatR

Calibrate the camera on the given xy coordinate

Usage

cam_cal_pt(x, y, K, k, F, max_iterations = 5, tolerance = 1e-09)

Arguments

x: x-coordinate in pixels
y: y-coordinate in pixels
K: intrinsic camera matrix
k: distortion coefficients (see [radial_distort()] for supported layouts)
F: focal length in millimeters (scalar or length-2 vector)
max_iterations: Maximum number of iterations passed to [radial_distort()].
tolerance: Convergence tolerance passed to [radial_distort()].

Value

calibrated point
