摘要: A calibration system and a method to be used in an image capture apparatus are disclosed. The calibration system includes a calibration appliance, a feature extraction unit and a processor. The calibration appliance has a plurality of mark points. The plurality of mark points is on the same plane to form a line segment with a known length. The image capture apparatus captures an image. Then based on the captured image, the feature extraction unit extracts at least three image feature points corresponding to the mark points. The processor calculates the inclination angle of the image capture apparatus, and the height between the image capture apparatus and the plane. Besides a line segment with a known length, the mark points corresponding to the image feature points may form a corner with a known angle, two corners with unknown but equal angles, or two line segments with unknown but equal lengths. Convenience for the calibration system is therefore improved.
