Introduction to Camera Calibration

Camera calibration is a fundamental concept in Computer Vision that involves determining the internal parameters of a camera, such as its focal length, principal point, and distortion coefficients. This process is crucial in various applications, including Structure from Motion , SLAM , and 3D reconstruction , as it enables the accurate estimation of the camera's pose and the reconstruction of the scene. Camera calibration is essential because it allows us to establish a relationship between the 2D image coordinates and the 3D world coordinates, which is vital for tasks such as object recognition , tracking , and scene understanding .

The importance of camera calibration lies in its ability to compensate for the inherent limitations and imperfections of camera systems.…
