How Photogrammetry Software Can Be Used In Crime Scene Reconstruction?

Photogrammetry can simply be defined as the measurement of photographs. It is a process for measuring any subject or crime scene captured in at least one or several images/video frames.

It has 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. The best photogrammetry software is used for crime scene reconstruction take measurements from a single photo as well.

The list below can be used as a quick check to determine whether the photogrammetric analysis may be possible.

1. There are some photos of the object to be measured from a different camera.

2. There are objects in the scene that has been known reference dimension or dimensions can be obtained after the photo was taken (eg, there is a table in a photograph of the length, width and height can be obtained).

3. The object to be measured is clearly visible in the photo and have distinguishable features (eg, the object should not be blurred or out of focus).

4. The size of the object to be measured needs to be sufficiently large relative to the entire image (for example, a skid mark that indicates a small mark on the way the photos in the distance, can not be measured with adequate accuracy).

5. Photos were taken with the same camera and same focal length (i.e. zoom) setting.

The above is simply a quick check and not having met one or more of the above criteria does not mean a photogrammetric analysis is impossible.
