Project update 8 of 12
After getting a few questions about using multiple Tau Cameras at the same time, we wanted to share with the whole community that it’s 100% doable. We’ve made some resources available - an example program and a 360˚ 4-camera mount - so you can make your own multi-camera setup in no time!
This example program uses the TauLidarCamera Python API and OpenCV to render depth data from all connected Tau Cameras in real-time!
When the program is launched it will:
multiplecameras.py program can be found on GitHub (along with the rest of the Python API example programs) at: https://github.com/OnionIoT/tau-lidar-camera/tree/master/examples
Instead of designing a multi-camera mount from scratch, we decided to make a 4-sided base compatible with the existing Tau Camera mount.
It links together four Tau Cameras on their individual mounts and can be attached to any standard tripod, giving you the ability to make a 360˚ depth map of your environment!
To 3D print your own, you’ll need:
Then you’ll need to:
multiplecameras.py example program as a starting point for your multi-camera work.
A few ideas on customizing this mount to suit your needs:
If you don’t need a full 360˚ view, you can still use the Base design. Here’s a few options for using fewer cameras:
Just be aware of balancing and tipping over in all cases!
Since the pegs are hexagon-shaped, you can try rotating the Tau Camera + Mount before attaching it to Base.
This design is meant to be a starting-off point! Feel free to design a version that meets your needs.
And don’t worry if the field of view of the Tau Cameras overlaps, there shouldn’t be any interference between Cameras.
If you have any thoughts, please let us know on the Onion Community. And absolutely let us know if you do make your own version!
