This thesis addresses the problem of calibrating a stereoscopic camera with a minimum of necessary post-processing. This is achieved through a two step procedure, the first step of which is a calibration of the sensors in rotation by means of laser diffraction, without attached lenses. The second step involves attaching the lenses and using a simplified conventional image-based calibration to determine the effects of motions of the optical centres due to lens focusing. Mounting considerations and long-term stability are also addressed. This method enables the construction of a stereoscopic camera which requires no interpolative rectification, with the calibration maintaining accuracy over a range of focal distances. Such a camera is built and calibrated, and tested to demonstrate the validity of the predicted error estimates. This approach is shown to be effective in producing stereoscopic images for display which meet the requirements of the human visual system. A comparison of this approach with previously published methods is presented. Some or all of the techniques described in this thesis may be incorporated into existing calibration schemes to improve the quality of the produced stereoscopic images. The improvements provided by a hardware calibration as described may be especially valuable in applications where maintaining full sensor resolution in the displayed image is desired.
