Measure suspect height and distances between points – photogrammetry

The goal of forensic digital reconstruction is to uncover new details about a case. 3D photo modeling, such as seen here, can retrieve crucial evidence from security camera video.

Determining height of a criminal seen in surveillance security video camera footage may help to disqualify or strengthen the case for an individual suspect.

There are several digital forensic steps and techniques one must take and utilize in order to accurately determine the height of a suspect seen in a security surveillance video recording. Specific, detailed measurements and digitally enhanced still-frames from various video camera angles need to be taken in order to properly build a 3D computer model of the location of the incident. Those still-images are then processed within a specialized 3D software program, allowing forensic video experts to get a detailed view of the scene of the incident.

Using photogrammetry, NCAVF can create a model and compare it to the recorded surveillance video evidence. In this way, we can get a close approximation of height, distances between points, and the speed of vehicles. To the left are a few images from a specific project.
