Abstract: A method for manually calibrating a camera mounted on a camera mount of a vehicle is provided. According to the present disclosure, the method includes acquiring an image data in a field of view of the camera based on an actual position of the camera. The captured image data is processed to determine a current pattern based on the actual position of the camera. The image data is displayed, wherein the current pattern is superimposed on the image data. The image data is also processed to display a marker pattern in the field of view of the camera. Thereafter a pre-determined orientation and/or a pre-determined height for the camera is calculated. Further, the actual position of the camera is manually adjusted to achieve the pre-determined orientation and the pre-determined height of the camera and to align the current pattern with the marker pattern.
