Scan Station technology is used to scan all crime scenes. A scan station uses laser technology to collect a large number of closely-spaced measurements and produce a “point cloud” of 3D points. By setting the scanner in several locations around a scene, investigators can capture multiple point clouds to develop a 3D snapshot of the location. Even small or subtle features such as shell casings or tire marks can be captured using the scanner and point cloud.
The scan data is then transferred to computers for archival and processing. The multiple scans are combined into a single point cloud, which provides a complete view of the scene.
Marking evidence Crime scene reconstruction is the use of scientific methods, physical evidence, deductive reasoning, and their interrelationships to gain explicit knowledge of the series of events that surround the commission of a crime.
