Abstract
A method for compensating hardware misalignments in a camera is presented. The camera includes a maneuverable part and a fixed part, and the maneuverable part is controlled by a steering motor system. In a first step of the method mechanical coordinates from the steering motor system is received, wherein the mechanical coordinates correspond to a pan and tilt position, the pan and tilt position having a complementary pan and tilt position. Next, pre-determined calibration data corresponding to the received mechanical coordinates is read from a memory wherein the pre-determined calibration data describes a relationship between a pan and tilt position and a complementary pan and tilt position, and then compensated coordinates are determined based upon the received mechanical coordinates and the pre-determined calibration data.
