Lcd and overlay?

I really suck at explaining stuff.

But what i want to know ia if its possible to.

Have a touch screen tft 3.5 display show what a webcam or camera is pointing at. And have on the screen a overlay of sensors.

So like if it was pointing at my guitars in my guitar room and have different temp sensors show up on the live feed.

Sorry if it makes no sense.

I also have a rpi 1 at my disposal. But would like to keep it pure arduino.

Of course you can but odds on not with the processor you are using.

PS WTF are you using.
