Abstract
We propose a calibration method for stereo camera with a large field of view (FOV) using zoom lenses. We adopted Magill’s formula, using intrinsic parameters with small object distances to calculate intrinsic parameters with large object distances. We employed a regular sized calibration board to calibrate extrinsic parameters in the small FOV, using zoom lenses to reduce the FOV, and then calculated extrinsic parameters in the large FOV. Verification experiments showed 3D reconstruction error was approximately 1 mm when the FOV is about 6 × 6 m. The proposed calibration method will broaden the application range for 3D digital image correlation in scientific and engineering fields.
