3D Modelisation

When a victim is discovered, the Rescue have priority, but it is important to be able to block the scene quickly.

To maintain the Crime scene’s integrity a blockade has to be done. It allows the Justice to observe the area as it was found, closer to the facts that may have occurred and for which the Justice finds it useful to carry out investigations. The crime scene technicians then conduct their investigations in a preserved environment. This conservation also allows detectives to observe the site and find the first elements of investigation. This is called the detective’s eye.

The French criminal procedure allows the Justice to keep under seal the place of the facts until the criminal trial. This sealing follows initial investigations and police interventions that will necessarily change and even alter the scene. And it must be added that it is sometimes necessary for the magistrate to return the area within a short time. That is why, it can be useful to realize a 3D modeling of the places to freeze the places as they were discovered and thus allow the judges to have at any moment a vision closest to the reality of the scene and this in 3 dimensions from their offices.

Pictures are often misleading because they represent in 2 dimensions a reality in 3 dimensions.

There are different techniques to quickly realize a three-dimensional modeling of places. All are visible on browsers common to all computers. They allow the user to move around the scene and visualize the different clues and their place of discovery. It is also possible for some to carry out precise measurements or even to place in the premises the hypotheses of investigation and the declarations describing the facts.
