A robust solution to the line-matching problem in photogrammetry and cartography.

In the overlapping area of adjacent photogrammetric models features are normally digitized in both models and are, therefore, subject to averaging. Though this process does not act as a significant difficulty when performed manually by the operator, it poses interesting problems when data are stored digitally and a computer solution is preferred. The solution proposed in this paper is based on discrete geometry and digital image processing methods, hence resembling the draftsman's problem-solving ability much more closely than methods which are based on Euclidean geometry. After extensive testing on a McIntosh personal computer, the software prototype has been implemented in a Kern MAPS200/300 digitizing and editing system.-from Author
