Original Abstract

This paper presents the procedure of mutual calibration of following 5 sensors: stereo pair of color CCD camera, stereo pair of thermal imager and "time-of-flight" (TOF) camera. The aim of calibration is to specify intrinsic parameter of each sensor including distortion and to determine translations and rotations among each camera coordinate systems. Proposed calibration procedure consists of a range calibration, initial calibration of intrinsic and extrinsic parameters and nonlinear optimization that minimizes sum of squares of the reprojection errors.
