AN INTRODUCTION TO DESKTOP PHOTOGRAMMETRY

This article describes a method for making direct measurements from photographs. Off-the-shelf software may be used to transform a scanned photograph from an oblique view with perspective, to a bird's-eye or vertical view. Once the photograph is transformed one may make measurements directly from the bird's-eye image. This method can be used on personal computer systems typically found at home, in the office, or at desktop computer rental services. The accuracy of this method ranges from 1 percent to 5 percent typically and depends mainly on the quality of the photograph. This method is useful in two important areas. The first is when a photograph is the only information one has about parts of an accident scene. The second case is where it is difficult or impossible to enter the scene to make measurements.
