Multi camera photogrammetry rig

It's done. The rig is complete. Five cameras with a tiny PC controller. Cable management will come later, but for now this is what the rig looks like.

I was inspired by Simon Che De Boer working with RiVR's rig, and since I had a bunch of cameras laying around, I figured "I could do that"

He's using the rig to capture textures for

My rig currently can handle 5 cameras, I have 3 Sony A6000's and 2 Sony A6500's, all using Sony 16mm f/2.8 lenses (figured it was better to keep them all the same).

The horizontal bar is on a quick release so I could remove that and hand hold it (it's a bit heavy but doable) so I could make it a mobile rig.

All are running on "fake" batteries (battery shell with wire running down to a USB plug) into 2 battery banks.  I have USB output running to a USB hub (also battery powered) that runs into a Chuwi Larkbox (tiny PC with a Celeron J4125, running Windows 10 & Smart Shooter 4 software.).

I found a 5 color set of velcro ties, and also colored hot shoe protectors, so I can color code each camera and cables (and label them in the Smart Shooter software).

I can remotely trigger via a wireless (or wired) trigger, or by remoting into the Larkbox with VNC or RDP and controlling the SmartShooter software.  SmartShooter is the cheaper version of Kuvacode's CaptureGrid (it's the same software with cameras limited to 8 and networked operation disabled), and I really wanted to use that because it runs on a Raspberry Pi and you can chain multiple Pi's up over a network to control tons of cameras, but their license is insanely expensive for what it is.  It was cheaper to buy the 8 camera version and a mini PC and still save thousands.

The software pulls the images and relabels/sorts based on which camera (which I've color coded) so I can see the full set to know if one didn't fire.

I can then use software like Resilio Sync to remotely transmit back to a base station machine to run real time photogrammetry sessions (haven't done that yet) or just pull the files later off the Larkbox and then process.

Tripod is mounted on a set of wheels so I can easily roll it through a warehouse environment or anything with a fairly smooth floor.

The tripod has a Black Rapid Tripod jacket wrapped around it, so there are lots of pockets to hold everything.

The other config was using a 10 foot carbon fiber monopod with mini super clamps, and mount all of the cameras vertically, so it's a photogrammetry stick (with shots every 2 feet). That would require shooting, twisting wrist, shoot again, repeat.

I'll post that later...
