Use multiple Astra cameras


I’m looking to use multiple Astra cameras to detect movement of people and use this detection to have a interactive area on a wall where I have multiple projectors. I use unity and C# to work, but I haven’t found how to use multiple cameras and it movement detection.

Hope someone can tell me how to do it.

I realized a framework for big interactive installations, all using Orbbec Cameras (8 in the video).
There is a single Unity application, with embedded projector blending and warping, and the input from cameras is directly mapped in the application’s screenspace for ease of programming.
Also notice the wall is completely non regular, the custom algorithm will adapt to any surface shape.

You can have a look at the realization here:
