In computer vision a camera matrix or (camera) projection matrix is a matrix which describes the mapping of a pinhole camera from 3D points in the world to 2D points in an image. Let be a representation of a 3D point in homogeneous coordinates (a 4-dimensional vector), and let be a representation of the image of this point in the pinhole camera (a 3-dimensional vector). Then the following relation holds where is the camera matrix and the sign implies that the left and right hand sides are equal except for a multiplication by a non-zero scalar : Since the camera matrix is involved in the mapping between elements of two projective spaces, it too can be regarded as a projective element. This means that it has only 11 degrees of freedom since any multiplication by a non-zero scalar results in an equivalent camera matrix. (Wikipedia).
Every digital camera has a sensor located behind the lens. The sensor is the part that actually captures the photo, much like the roll of film in a film camera. We hope you enjoy! To learn more, check out our written lesson here: https://edu.gcfglobal.org/en/digitalphotography/
