How to 3D map a crime scene with an Autel EVO Max 4T
To 3D map a crime 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 of the scene with image walkthroughs, annotations, and a chain-of-custody log. 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 crime scene documentation 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.
Add the interior
Use the EVO Max 4T for the exterior. Record the interior with a phone (4K recommended, 60fps, wide-angle, slow and smooth) or a 360 camera, upload it with the Interior Mapping toggle on, and merge both models with 3D Overlay (Premium).
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 crime scene documentation
3D Overlay
Stack an interior model on the exterior drone model in one viewer so investigators walk the whole scene without switching files.
Line of Sight
Place up to two observer points and see visible areas in green and blocked areas in red. Included with Pro models and Public Safety & Enterprise.
Case Gallery and Image Walkthroughs
Attach evidence photos to annotations and open auto-generated images along the capture path for finer detail.
Security and custody
Hosted on AWS GovCloud (US) with CJIS compliance maintained for Public Safety & Enterprise subscribers. Model access, user actions, and sharing are logged.
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.
Can SkyeBrowse map the inside of a building at a crime scene?
Yes. Record slow, steady video with a phone, 360 camera, or FPV drone, turn on the Interior Mapping toggle at upload, and use the Scale Tool with a known measurement when the video has no GPS data.
Is SkyeBrowse CJIS compliant?
SkyeBrowse is hosted on AWS GovCloud (US) and full CJIS compliance is maintained for Public Safety & Enterprise subscribers.
