Stereoscopic camera system calibration system creates calibration images and calculates correction matrices using precise scanning of collimated source

摘要

A stereoscopic camera (C1, C2) system (6) calibration system creates a coordinate correction table for each sensor from grey level comparison of images of a fixed collimated source (2) taken by precise translation and scanning in angle over the field of view on a test bed (5) with reference coordinate systems derived using optical reference cubes (7, 8).
