What are the methods of camera calibration?
The method involves: (1) Taking a terrestrial exposure with the camera to be calibrated, and selecting one well defined point in each of the four quadrants of the negative plate; (2) With a theodolite at the camera station, observing the horizontal and vertical angles sub- tended by all possible pairs of the four ...
What is camera calibration and why it is important?
Geometric camera calibration, also referred to as camera resectioning, estimates the parameters of a lens and image sensor of an image or video camera. You can use these parameters to correct for lens distortion, measure the size of an object in world units, or determine the location of the camera in the scene.
What is camera calibration in photogrammetry?
Camera calibration is the process of finding the true parameters of the camera that took your photographs. Some of these parameters are focal length, format size, principal point, and lens distortion.
