Popis: | A large-size 2D target cannot be used for calibration in the application scenarios with confined spaces, neither can traditional 1D target because the need of constrained motion. To solve this problem, a camera calibration method based on two-cylinder (TC) target is proposed. The TC target is placed in the Field of View (FOV) arbitrarily and images of the target are acquired from multiple views, then the camera can be calibrated by establishing the perspective projection relationship between the TC target and its projective contours in each view. The experiments with both synthetic and real data show that the proposed method has better anti-noise ability and higher accuracy compared with small-size 2D target. |
