Abstract

Novel tools and techniques for defining a search range for conjugate points in a set of images. In one technique, an intra-overlap area in two images can be used to define a search range in which a conjugate point can be found; in an aspect, this search range might be expressed as a distance range from a station at which one or both of the two images were captured. That distance range can be used to narrow the search range in an image captured from another station, substantially reducing both the computation time to identify a conjugate match and the likelihood of identifying an incorrect match.

First claim

What is claimed is:

1. A system, comprising:
an image capture system comprising a plurality of image sensors, the image capture system configured to:
when oriented at a first station, capture a first image with a first image sensor having a first center of projection;
when oriented at the first station, capture a second image with a second image sensor having a second center of projection;
when oriented at a second station, capture a third image with one of the plurality of i…
