Connecting stereopi to two displays?

Post by MWaddell »

I know it's possible to connect the stereopi to a single screen (and indeed this is a strength), but I want to do a project where I connect a single stereopi (with the two cameras) to two separate screens. More specifically, I want to connect it to two of these https://www.amazon.com/Vufine-006011-We ... 36&sr=8-10

You can see someone connect a single raspberry pi camera to one of them here: https://www.youtube.com/watch?v=px2hdZJLC3A&t=1s

My question is if it's possible to connect the stereoscope to two of these things (essentially displays that you connect to via an HDMI connection)? And if so, would I experience some of the issues the stereopi is meant to address (latency, differing delays between trying to sync two cameras before the stereopi came around, etc...).

Would love some guidance!

Usually for the VR applications (like helmets) it is used a couple of screens (for each eye), but with a single HDMI input, like this:

Or round screen (magic leap?) like this: https://imall.com/product/Wisecoco-Real ... 9225940/ru
You can find more options by googling.
So you just provide a single HDMI output, and hardware splits image on left and right.
As for your mentioned screen - I did not find any solutions for "splitting" image for such a glass-related tiny monitors.
You can look at tilt5 project - they use a couple of a tiny HD projectors for their VR glasses. But, to say the true, I was not able to find some more details on hardware they use.
p.s. If you decide to go this coupled-screen way, please take into account, that RPi can give you 1920x1080 maximum resolution (but not 4K) from the cameras.

Thanks, this is actually really helpful. I really just need the board that splits the images into two separate screens - I can figure out how to connect the displays I linked to it fairly easily I would think. I'll keep the forum posted!
