Hi, i had the chance to try the ZED camera, it’s an interesting one.
Depth quality under 10m is alright, but there is still some noticeable noise more than kinect or asus cam, after 10 meter the noise is to high to make a difference between someone or some noise.
The camera comes with ir filter, so don’t think using it with ir illuminator , the zed won’t see the ir. This is a big limitation when you want to use it for tracking people over an interactive floor because depth algorithm get a bit crazy when dealing with flat moving surface like a screen or a projection, sometimes it work fine sometimes it output some strange depth. Light change is also creating some depth noise.
An infrared version would be much better for tracking … depending on your application it might be a good choice or not.
