Abstract
In a system and method of calibrating a stereoscopic camera, a target pattern is electronically displayed on a display. The camera to be calibrated captures images of the target pattern using a stereoscopic camera while the displayed target pattern is altered over time. The captured images are analyzed and calibration parameters for the stereoscopic camera are determined.
