3D Scanning Projector
Posted: 10 Feb 2021, 01:03
Hi all,
Everyone likes to post their latest scans and tech, unfortunately much of what we do can not be shared. Once in a while we get to do some "personal" type projects also.
So I thought I'd share this new toy we made for ourselves recently. -- What is it you ask? --
It's a custom made projector just for 3D scanning. There's a couple nice little features to this little projector.
We looked at being able to swap lenses, but doing that would increase complexity and cost way too much.
So just an internal prototype for now possibly for use in a future scanner. If there's interest we will do a limited manufacturing run for DIY'ers who want one, I will post additional test results as we do them. The projector is built of our H3 handheld scanning projector technology so the projector is tuned for speed.
This is a slow scan using 3mp cameras.

- Aluminum body so it survives and mounts
- Rigid Mount points for tripods, and camera bars
- High speed projection -theoretically up to 5000 FPS -
- GPIO Triggers for your cameras for high speed scanning
- Fast enough for DIY Handheld Scanning - will post a video later
- Direct Axis projection, - you don't need to tilt your projector relative to your cameras.
- Uses latest TI DLP chipsets, (square pixels) - many *new* projectors uses old DLP projection technology
- Completely linear phase patterns (for accurate scans )
- Single Cable Control -

Current Limitations
- FS3D control only (sorry requires custom drivers)
Basler Cameras support only
