Measuring and recording the crime and traffic accident scenes carefully can be a lengthy task, but collecting this information is vital to the investigative process. New technology offers a way for these scene investigations to improve and strengthen their precision.
For example, laser scanners accelerate inquiries into incidents. These devices can capture millions of observable data points quickly and accurately at a crime or accident scene. In later analysis, these measurements are processed, and the data can be converted into a scene model exactly as it was at the time of recording. Here are three ways in which a 3D laser scanner can efficiently and effectively help your agency process scenes.
1. It captures a comprehensive record.
The accuracy of evidence gathering can be greatly enhanced by a 3D laser scanner because the entire scene is collected at millions of image data points. The laser will see everything that was registered, and the data points will be called from a cloud of 3D points.
All scene details are captured, which provides accurate evidence representation, including blood spatter, skid marks, artifact location, and charring pattern positions. You can later use the point cloud to take measurements digitally, simulate scenes, create graphs, and display walk-throughs for court presentations.
2. It preserves evidence and saves time.
Police can use a laser scanner to record all the evidence on the scene in much less time than conventional manual methods take. This is particularly helpful when clearing the road, and the recorded point cloud never changes, unlike a dynamic crime or crash scene.
When your agency is ready, the data is stored for analysis, and you never need to go back to the scene to take more measurements. The 3D point cloud can be used by researchers and forensic experts to build a scene model, explore scenarios, analyze perspectives, and assess positions, and after the event.
3. It makes recreating the scene simpler.
Law enforcement agencies may use the point cloud to generate animations and diagrams to recreate the scene in order to provide a convincing testimony in court. Investigators can then use a 3D model created from the point cloud to show exactly how it looked at the time of the event to guide the judge or jury through the case.
How to Use Laser Scanners
Before, scenes are recorded scenes using tape measurements. Laser scanners make things simpler for a Las Vegas private investigator or anybody else in the field, more particularly crash reconstructionist. There will be less time required to record crash scenes using the scanner.
For investigators, scanners become a way of life. It is precise, efficient, effective, and generally inexpensive. It only takes 30 minutes to scan the scene and 60 minutes to complete the final diagram and analysis from the time the investigators arrived on the scene. Vital measurements from the scene are collected to analyze the crash and produce persuasive displays for court presentations. This new technology makes things easier for police officers and the people involved in the accident.
