In science and engineering, an intrinsic property is a property of a specified subject that exists itself or within the subject. An extrinsic property is not essential or inherent to the subject that is being characterized. For example, mass is an intrinsic property of any physical object, whereas weight is an extrinsic property that depends on the strength of the gravitational field in which the object is placed. WebK — Camera intrinsic matrix 3-by-3 identity matrix (default) 3-by-3 matrix. This property is read-only. Camera intrinsic matrix, specified as a 3-by-3 matrix. The matrix has the format [f x s c x 0 f y c y 0 0 1] The coordinates [c x c y] represent the optical center (the principal point), in pixels.

Assuming your matrix is an extrinsic parameter matrix of the kind described in the Wikipedia article, it is a mapping from world coordinates to camera coordinates. So, to find the position C of the camera, we solve. 0 = R C + T C = − R T T ≈ ( − 2.604, 2.072, − 0.427). The orientation of the camera is given simply by R T.
