What are the parameters of camera calibration?

Camera parameters include intrinsics, extrinsics, and distortion coefficients. To estimate the camera parameters, you need to have 3-D world points and their corresponding 2-D image points. You can get these correspondences using multiple images of a calibration pattern, such as a checkerboard.

What information is contained in the intrinsic camera parameters?

In addition to the focal length of the camera f, this intrinsic parameter matrix includes m_x and m_y, the number of pixels per x and y unit of image coordinates, respectively; (p_x, p_y), the coordinates of the principal point of the image; and s, the skew (deviation from rectangularity) of the pixels.

What factors affect the intrinsic parameters of a camera?

On the other hand, the intrinsic parameters of a camera depend on how it captures the images. Parameters such as focal length, aperture, field-of-view, resolution, etc govern the intrinsic matrix of a camera model.

What is camera intrinsic matrix?

The intrinsic matrix allows you to transform 3D coordinates to 2D coordinates on an image plane using the pinhole camera model. Equations like the following commonly represent the intrinsic matrix as K: The equation expresses all values in pixels.
