Abstract
Advances in multiple view computer vision techniques have made it possible to make highly accurate three-dimensional (3D) measurements using calibrated stereo image systems. Recent experiments conducted at Sandia National Laboratories have demonstrated the feasibility of applying these techniques on an X-Ray system. Acquiring measurements from stereo image systems, be it visible or x-ray, require the estimation of the system’s intrinsic and extrinsic parameters via a calibration process. There are several calibration methods depending on the system’s configuration and its intended use. In most cases, one or more image pairs of a calibration artifact such as a 3D object of known dimension or a 2D target board are processed to estimate the system’s calibration parameters. For this paper, methods based on both types of calibration artifacts will be discussed along with experimental results.

Note: Due to a mistake during the image acquisition, the 315° and 330° image pairs are duplicates of the 300° degree image pair. This is clearly visible in the 3D results shown in Fig. 25.7.
