Photogrammetry

As defined by the American Society for Photogrammetry, Photogrammetry is “The art, science and technology of obtaining reliable information about physical objects, and the environment through a process of recording, measuring and interpreting photographic images.” In many cases photographic images are taken from video frames.

Using Photogrammetry, the height of a suspect in crime videos from such places as convenience stores can be calculated scientifically. There are different ways in which the calculations can be performed. For example:

Where there are known, measurable objects still present where they were, and in the same location as at the time of the videotaped incident. Known objects could be counters, merchandise racks, shelves, newspaper stands, etc.
Reverse Projection Photogrammetry can be performed by placing an object of known dimension into the scene and capturing the images using the same security camera in the same position as it was the time of the incident. For this type of analysis, a visit to the scene is necessary. However in some types of photogrammetry measurements can be made by an investigation in that area and forwarded to our lab.

Photogrammetry technology can also be used forensically in situations such as accident reconstruction.

As experienced expert analysts, our highly trained and qualified forensics team uses top of the line hardware and software technology to carefully handle and thoroughly analyze your evidence audio, video, and photographic media. We can isolate, separate, enhance, and authenticate all relevant aspects of audio and video recordings in order to produce expert evidence backed by many years of master experience. As an expert witness in the courtroom, our testimony from the witness stand will contain provable facts and relevant demonstrative evidence that can often make or break a case.
