A method for calibrating a vehicular camera of a vehicular vision system includes placing a target with a first portion having a first geometric pattern and a second portion having a second geometric pattern within the field of view of the vehicular camera, and capturing image data with the camera representative of the field of view of the vehicular camera. Two edges of both portions of the target are detected, and edge pixels of the detected edges are determined. First and second vanishing points of the target in the captured image data are determined based on the determined edge pixels of the respective first and second portions of the target. Camera orientation is determined based on location of the determined first vanishing point relative to location of the determined second vanishing point. The vehicular camera is calibrated based on the determined camera orientation.
