3D Laser Scanning for Accident Reconstruction

Laser Scanning and Drone Photogrammetry for Accident Sites

GPRS Laser Scanning experts use state-of-the-art laser scanning equipment and drone photogrammetry platforms to provide a new perspective in preserving and analyzing complex accident sites and incident scenes. With conventional techniques, subjective judgments can be made about what information should be recorded at the scene.

By using a 3D laser scanner, a more objective approach is used – everything within the line of sight of the laser is captured. By repeating the scan from additional positions and then merging the resulting data, a comprehensive 3D point cloud of the scene is created. This provides investigators with the ability to “revisit” the original scene for further spatial analysis or to collect additional data via their computer screen. Plus, this data can be accurately merged with any initial scene survey data captured. This technique is ideal for documenting runway, taxi and roadway layouts, flight path obstructions, accident scenes and wreckage layouts.

GPRS has partnered with DVI Forensic Labs to provide comprehensive nationwide coverage for all of DVI's accident reconstruction services. GPRS's mission is to provide the best-in-class 3D laser scanning and drone photogrammetry services, capturing unbiased data for accident investigations. Our expert project managers, engineers and CAD technicians are ready to serve your needs in an accurate and efficient manner.

GPRS Laser Scanning experts use industry-leading Leica laser scanners to collect up to 2 million measurement points per second with 2-4 mm accuracy at a range of up to 270 meters for each scan taken. GPRS can also construct customized deliverables, such as 2D drawings or 3D models with the millions of sub-centimeter data points collected.

GPRS uses drone photogrammetry to improve the process of accident investigation. GPRS has optimized a workflow to ensure that HD video and HD photos are quickly and accurately collected. The resulting images and maps of the scene, along with accurate distance and angle measurements, are important for the reconstructionist or the forensic specialist. Viewpoints can be changed to any location within the scene. GPRS can construct customized deliverables, such as 2D orthoimages or fly-through videos for evidence in court.

GPRS 3D Laser Scanning Services for accident investigations include:

  • Point Clouds
  • 2D CAD Drawings
  • 3D Models
  • 2D Orthoimages
  • HD Video Documentation
  • HD Photo Documentation
  • 360° Panoramas
  • Flythrough Videos
  • Drone Photogrammetry

The images generated by laser scanning and drone photogrammetry provide irrefutable demonstrative evidence that can be used at trial or mediation. Opposing parties can be assured that subject/exemplar data and evidence will be collected, documented, and shared in a manner consistent with ASTM standards and industry best practices.

3D Laser Scanning Pricing

The cost of 3D laser scanning can vary widely depending on your project scope. GPRS customizes every quote specific to your project’s needs. GPRS Project Managers use 3D laser scanners to capture every detail of your site, delivering building dimensions, locations, and layout with millimeter accuracy. This can include the aboveground structural, architectural, and MEP features, plus underground utility and concrete markings. Our Mapping & Modeling Team can deliver point clouds, 2D CAD drawings, 3D BIM models, 3D Mesh models, TruViews, and Virtual Tours at any level of detail.
