How to 3D map a crash scene with an Autel EVO Max 4T
To 3D map a crash scene with an Autel EVO Max 4T, fly it manually in its native app and record one continuous video, then upload the video to SkyeBrowse. SkyeBrowse processes it in the cloud at about one minute per minute of video and returns a measurable 3D model and top-down orthomosaic of the crash scene that you can measure, diagram, and export. Upload the drone's .ASS subtitle file with the video to georeference the model, and Public Safety & Enterprise models reach 0.1 inch accuracy without ground control points.
Applies to the Autel EVO Max series, including the EVO Max 4T.
Capture the crash reconstruction with the EVO Max 4T
Manual flight
The SkyeBrowse Flight App does not support the EVO Max 4T, so fly it in its native app. Record one continuous video while moving around the scene. Keep the camera pointed down at the subject, keep zoom locked, move smoothly, avoid excess sky, and finish with overlap where you started.
Georeference the model
Turn on .ASS subtitle recording on the Autel aircraft before takeoff. Upload the .ASS file with the video and SkyeBrowse georeferences the model automatically.
Autel setup tutorial
Follow the SkyeBrowse Autel EVO II and Max 4T tutorial to enable .ASS subtitle files for georeferencing.
Process the video
Upload the MP4 or MOV file at app.skyebrowse.com. Processing runs at about one minute per minute of video, and most models are ready 5 to 10 minutes after upload. Public Safety & Enterprise models reach 0.1 inch accuracy and Commercial models reach 0.5 inch, with no ground control points.
Outputs and measurements for crash reconstruction
Distance, area, and angle
Measure skid marks, vehicle positions, and roadway geometry directly on the 3D model or orthomosaic.
Crush & Claims Analysis
Identify each vehicle, align an undamaged reference model with the damaged scan, and review crush depths, CDC classification, and derived delta-V with stated assumptions. Free on every plan through October 31, 2026, then included with Public Safety & Enterprise models.
Factual Diagram
On Public Safety & Enterprise models, generate a court-ready PDF with a top-down overview, sketch page, annotations, measurements, scale bar, and compass when available.
Exports
Download LAZ, GLB, OBJ, USDZ, GeoTIFF, and CAD files for forensic and CAD software on export-enabled models.
Frequently asked questions
Does the SkyeBrowse Flight App support the Autel EVO Max 4T?
No. Fly the Autel EVO Max series, including the EVO Max 4T manually in the native app and upload the MP4 or MOV video through Universal Upload at app.skyebrowse.com.
How do I get accurate measurements from EVO Max 4T video?
Turn on .ASS subtitle recording on the Autel aircraft before takeoff. Upload the .ASS file with the video and SkyeBrowse georeferences the model automatically.
Does SkyeBrowse determine how a crash happened?
No. SkyeBrowse documents and measures the scene. AI approach-path predictions are editable hypotheses for review, and AI Factual Diagram drafts neutral factual descriptions only. Neither establishes fault, speed, or cause.
How accurate is a SkyeBrowse crash scene model?
Public Safety & Enterprise models reach 0.1 inch accuracy and Commercial models reach 0.5 inch, without ground control points. Placing a known-size object in the scene gives you a check measurement.
