摘要-;
Extrinsic calibration or coordinate frame calibration
of multiple cameras is a critical step for conducting three-dimensional
measurement effectively from visual images. Based on the
concept of relativeworld coordinate system, an efficient method for
calibrating the coordinate frames for multiple cameras has been
developed in this paper. Its basic idea is to compute the transformation
matrices between cameras from their individual transformation
matrices to a relative world coordinate system such that
its absolute coordinate information is not required and methods
for single camera calibration can be utilized. A solution procedure
that separates rotational parameters from translation parameters
of transformation matrices has been developed where the rotational
parameters are obtained first by solving a set of nonlinear
equations involving two Euler angular parameters, while the translational
parameters are then calculated analytically. In addition,
equations for calculating the depth information and matching lines
in general cases have been presented. Finally, a detailed numerical
investigation regarding the error and sensitivity analysis of the proposed
calibration algorithms has been performed extensively.
