ABSTRACT:
A mechanism for determining parallax between first and second digital images employs an iterative image pattern search and correlation process, which is able to rapidly determine the parallax for each pixel that is common to the images captured by a stereo image pair. By the initial use of a dispersed sub-array of reference point pixels distributed throughout a first image array, a similarly dispersed sub-array of tie points, to be used as starting points for subsequent, more densely populated search and correlation steps, can be rapidly obtained for the second image array. The derived parallax values may then be subjected to an interpolation function to sub-pixel accuracies. Once the parallax between the first and second image arrays has been derived, elevations can be computed using a conventional parallax-dependent mechanism.
