Abstract

The aim of this thesis is to outline a versatile stereo video measurement system capable of extracting three-dimensional information from a pair of stereo video images.

When stereo images are used to obtain measurements there are two points which have to be noted and these are that the distortions due to each camera system need to be modelled and that the relative orientation between the cameras needs to be calculated from known control points located in both images.

The City University stereo video system is fully described together with an outline of how measurements may be carried out with the aid of an operator who provides a means of obtaining corresponding stereo points.

An automated technique of acquiring these measurements is then described. The approach used to obtain automatic range information from the stereo images is that of estimating the range image by means of an area correlation process and then iteratively improving upon the range image by successive application of the mapping transformation of coordinates from one stereo image to another.
