Paper Abstract

In forensic applications of photogrammetric techniques any measurable information is a precious commodity. In this paper, we describe the development of a new geometrical approach to photogrammetric measurements. While classical photogrammetry requires knowledge of point measurements, in this approach we exploit other geometrical constraints that are often available in photo and video forensic evidence. In Part I paper, the first in the series, we introduce line constraints and demonstrate algorithms that combine point and line measurements.
