Camera Self-calibration in Scheimpflug Condition for Air Flow Investigation.

Camera calibration is a necessary preliminary step to ensure high quality measurement in a section of a flow. The bundle adjustment technique is based on redundancy resulting from multi-viewing the calibration target. In this paper we proposed a well-adapted protocol for self-calibrating a Scheimpflug model. Such a protocol allows calibration by hand positioning a laser printed target. Experimental results indicate that with only 5 views we can accurately calibrate a Scheimpflug camera in Stereoscopic Particle Image Velocimetry condition. [ABSTRACT FROM AUTHOR]
