Accident reconstruction via digital close-range photogrammetry

Abstract

With the ever wider adoption of spatial information analysis, there has been an increasing awareness of the importance of 3D data acquisition systems to support traffic accident reconstruction and forensic analysis. In an application such as accident reconstruction, GIS and CAD systems have limited utility without the underlying data. Digital close-range photogrammetry displays many attributes which make it a well suited technology for the provision of the necessary 3D measurement data. The application of photogrammetry to accident reconstruction is not without difficulties, however. These include accommodation of the generally very poor, near-planar network geometries encountered and the ne..
