What is pi capable of

Tue Sep 14, 2021 8:06 pm

Hi I’m new to the pi scene and I have a project to create for collage,
I am wondering if it is capable of 2 cameras
Camera 1: for lane assist
Camera 2: monitoring facial expressions
Both of the above at the same time
Also running multiple programs in the one instance,
My project is to monitor a drivers vitals both through cameras and sensors, then interact via canbus in the car,

Any info would be helpful

In case you want to use two Raspberry cameras at the same time, you would need a Raspberry Compute Module -- all other PIs support only a single CSI camera. Adding USB camera(s) allows to satisfy your requirement for normal PIs.
Also running multiple programs in the one instance,
Raspberry Pi OS is Linux -- you can run many programs at once (even on single core Pi0). Newer Pi models all have 4 cores:

Those apps don't need high resolution.
Even 320x240 might be enough.

Arducam have a bunch of cameras down to SPI ones even a Pico can use.
2 x CSI cameras and 6 SPI cams?
Even more if you use their CSI mux boards.

Libcamera now has a detect app, might be a place to start.
