Calibration Quality & Image Rectification

FLIR Stereo Vision cameras are factory-calibrated for lens distortion and camera misalignments, to ensure consistency of calibration across all cameras and eliminate the need for in-field calibration. During the rectification process, epipolar lines are aligned to within 0.05* pixels RMS error. Calibration results are stored on the camera, allowing the software to retrieve image correction information without requiring camera-specific files on the host computer. This allows seamless swapping of cameras and easy use of multi-camera systems. The camera case is also specially designed to protect the calibration against mechanical shock and vibration.

Images can be rectified to any image size, making it easy to change the resolution of stereo results depending on speed and accuracy requirements. Camera calibration and rectification are key to getting high quality disparity images from a stereo camera.
