Enhancing Traffic Accident Investigation with EinScan Libre

Discover how EinScan Libre transforms traffic accident investigation with wireless, efficient 3D scanning for faster, safer, and more accurate scene documentation.

When traffic accidents happen, every second counts. Investigators must secure the scene, collect evidence, and clear the road as quickly as possible to avoid secondary accidents. Traditional methods are not only time-consuming but also incomplete, leaving gaps that can compromise later analysis.

This is where EinScan Libre, an all-in-one laser 3D scanner provides a step change in capability.

Challenges of Traditional Accident Investigation

Traditional accident investigation relies on tape measures, sketches, and photos, often requiring 2–3 hours per case. These methods are slow, labor-intensive, and often incomplete. Key evidence can be distorted or missed, while prolonged road closures during data collection increase traffic risks. As a result, investigators struggle with inefficiency, limited accuracy, and fragmented records—all of which undermine reliable accident analysis.

To address these shortcomings, 3D scanning offers a faster, more accurate, and more reliable way to capture accident scenes in full detail.

3D Scanning: From Flat Records to Full  Reconstruction

3D scanning transforms accident investigation with efficiency and non-contact operation. EinScan Libre, an all-in-one laser 3D scanner, brings these advantages directly to the field, making it easier than ever to document complex accident scenes.

 

Capturing collision damage with EinScan Libre

Capturing collision damage with EinScan Libre

  • Wireless & standalone design: With a built-in NVIDIA processor, OLED display, and swappable batteries, EinScan Libre works wire-free and computer-free. Investigators can start scanning immediately, anywhere, without setup delays.
  • Fast, flexible capture: 3 scanning modes adapt to different needs.
    · Laser HD Mode enables maker-free, high-detailed scanning with rich texture, such as dents, scratches, fractures, or paint peeling.
    · IR Rapid Mode records large vehicle areas quickly and without markers, ideal for capturing the overall scene.
    · IR Adaptive Mode is ideal for reflective and black surfaces, delivering reliable results.
  • Safety and efficiency: By significantly reducing investigation time, road closures are shorter, minimizing secondary accident risks. Non-contact scanning also avoids damaging fragile evidence like broken glass or deformed plastic parts.

The result is a complete, interactive 3D model that can be rotated, zoomed, and inspected from any angle. Investigators gain clear insights into collision forces, directions, and vehicle trajectories—evidence that traditional methods often fail to capture.

From Data Collection to Data-Driven Investigation

With 3D scanning, investigators gain far more than a static record—the output is an interactive, analyzable digital asset. This shift enables accident analysis to move from experience-based judgments to data-driven conclusions.

Deformation comparison

Damaged vehicle scans can be directly compared with CAD data or undamaged models. Using color-mapped deviation analysis, investigators can clearly see the depth and direction of deformation. In rear-end collisions, for example, the extent of bumper collapse can be correlated with crumple zone compression to estimate impact speed differences.

Evidence chain integration

3D models can be synchronized with CCTV footage, dashcam recordings, and Event Data Recorder (EDR) outputs. By spatially linking vehicle positions, skid marks, and debris fields, investigators create a comprehensive “3D evidence chain” that validates statements and supports reporting, insurance claims, and forensic proceedings.

Benefits: Redefining Accident Investigation

EinScan Libre transforms traffic accident handling from manual, paper-based methods into a fully digital, data-driven process.

  • Faster scene clearance – A rapid “scan-to-upload” workflow minimizes road closures and reduces secondary accident risks.
  • Smarter use of resources – A single investigator can do the work that once required a full team.
  • Trustworthy evidence – Tamper-proof 3D records are admissible in court and enhance transparency.
  • Lasting impact – The growing database of crash data supports safety research and guides vehicle design improvements.

By combining wireless mobility, efficiency, and intuitive operation, EinScan Libre empowers investigators to work faster, safer, and with greater confidence at the scene. As transportation systems evolve, 3D scanning is becoming an indispensable ally, enabling accurate investigations today and helping build safer roads for tomorrow.
