Paper Abstract

In digital photogrammetry, difficulties are often experienced when automatically matching differing viewpoints of similar targets, such as retro-reflective targets. In this paper, an alternative target matching technique to the epipolar line method is developed. The method, which is combined with a bundle adjustment process, is based on a 3D intersection and `epipolar plane,' as opposed to the 2D intersection of the epipolar line method. The theory of the approach is described and discussed. Comparisons are made between the epipolar line method and the 3D matching method. Results from both simulation and practical testing are given and critical evaluation is made of the technique.
