Guide To Photogrammetry in Forensic Science

Photogrammetry is the art and science of extracting 3D information from photographs. The process involves taking overlapping photographs of an object, structure, or space, and converting them into 2D or 3D digital models.

The best photogrammetry software is used in the forensic investigation when images are the only record for finding clues in crime scene investigations, or when direct measurements of a subject are not safely or conveniently obtained.  Automatic forensic photogrammetry software with the ability to produce an accurate bio-metric measurement of a suspect’s dimensions (e.g. height), and crime scene measurements from surveillance video and photographs.

Classification of Photogrammetry

Photogrammetry is classifieds as:

  • Aerial – It typically focuses on topographic products such as terrain or topographic maps.
  • Close range – It uses non-specific, everyday cameras to create drawings and 3D models of items, locations or buildings.

Various media can be used for photogrammetric analysis. Some of them are:

  • Photos
  • Videos
  • Broadcast news coverage
  • Stationary surveillance systems installed in buildings
  • Mobile surveillance systems installed in emergency vehicles, trains, buses, etc.

Photogrammetry software is a general photogrammetric tool-set for measuring any subject or crime scene captured in at least one or several images/video frames.

Experts have years of experience in solving crime scene investigation cases. The detection, collection, documentation, and preservation of physical evidence are key elements involved in every crime scene. Experts will assist in the development of new techniques involved with crime scene examination and can elaborate on those already obtained.
