Weather Conditions for Planning Aerial Surveys

Camera calibration is the process of determining the intrinsic and extrinsic parameters of a camera system.

Focal length (f) represents the distance from the camera's optical center to the imaging sensor.

The principal point (c) defines the center of the image where the optical axis intersects the imaging sensor.

<p>Extrinsic parameters describe the spatial location (X, Y, Z) and orientation (ω, φ, κ) of the camera in the coordinate system.</p> Signup and view all the answers

<p>Radial distortion is caused by imperfections in the lens, leading to distortion towards the edges of the image.</p> Signup and view all the answers
