Proposal and application of real-time calibration of baseline length in single-camera stereo system.

3D image processing algorithms for real-time calibration of the baseline length in a single-camera stereo system are presented in this paper, and the performance of less than 0.03 mm depth measurement in precision and about 0.45 s processing time in the inspection are also presented based on the applications to the experimental equipment. It is technically noted that the baseline of this single-camera stereo system was precisely calibrated by the image processing procedure. The scope of application of this simply configured stereo system could be expanded to the wider fields of industrial 3D measurements. © 2009 Wiley Periodicals, Inc.
