Turning incident scenes into virtual 3D models
Armed with a mouse, investigators can do a number of things with the interactive model. One is moving around the virtual scene. If they want to see in detail a specific location, they can click on it. Another feature of the model is measuring distances and heights by calculating the line of sight to verify witness testimonies.
Field assessment with Fairfax County Police
The uniqueness of 3D-Hawk is that it is made mostly for the police and other first responders such as firefighters and bomb squads.
In May 2018, the Fairfax County Police Department (Virginia) was able to try this new tool during an Operational Field Assessment with S&T and its Israeli partners. The 3D-Hawk was tested on three types of mock scenes – a car crash, an outdoor crime scene involving a car bomb explosion, and an indoor homicide.
“First responders with no prior access to the tool were able to record a scene in approximately five minutes. The full rendering of the environment can take up to 30 minutes,” said Nenneman. ”This is significantly less time than the capabilities that currently exist for first responders.”
The fake homicide scene depicted a victim sitting on a sofa, his head tilted back, a gun and a suicide note in front of him. The Israeli company asked a Fairfax County Police detective to go around the room with the video camera and shoot the whole room, including its walls, the table beside the victim, and finally, the pistol. Next, the detective turned the videos into multiple 3D models, which he then combined using the 3D-Hawk software.
“You want to show how each layer of the 3D model is a layer in a story that a crime scene investigation officer needs to tell himself, his commander, and the court,” said Gil Koubi, Vice President of Marketing for B-Design3D. “The idea is to empower police forces with the power of 3D.”
Both the Israeli police and Fairfax Police have incorporated the 3D-Hawk technology into their work and have created thousands of models since the assessment in May.
“I am very impressed with the equipment and the training that we received,” said Second Lieutenant Richard Buisch, Fairfax County Police Crime Scene Section. “The 3D-Hawk is much more effective and efficient, and much easier to use than other 3D scanners we have dealt with.”
He said the technology can be used successfully to further document crime scenes and reconstruct crash scenes, instead of just taking photos.
After the assessment of the tool, the lieutenant and his detectives provided feedback to S&T and its Israeli partners regarding upgrades involving indoor scenes, ballistic evidence, projector viewpoints and bloodstain patterns.
“If S&T came to me to test more technologies, I would agree 100 percent,” said Buisch. “I think my team and my detectives really benefited from it, and I could see us moving forward and possibly trying other devices that can help us in in the field to close criminal cases.”
As part of the bilateral agreement, S&T provided three prototypes to be used on a rotational basis by state and local law enforcement agencies; and the government of Israel provided three systems to several of its police units. The Fairfax County Police continue to operationally pilot the 3D-Hawk they used in testing, as are the Ohio Highway Patrol and the Federal Law Enforcement Training Centers.
In the future
The Israeli company B-Design3D continues to improve its product based on the feedback it received so that the police can do their jobs better and faster.
“Because of the ease and the relatively brief time it takes to collect an accurate representation of the environment, it is believed that this tool can be used much more frequently than other tools, expanding the use of 3D modeling and law enforcement evidence,” said Nenneman.
