What sort of camera should I use?

Jorgen

Hi!

I'm looking for advice about a camera that combines accurate depth perception (between ~0,5m and >=6m) with decent field of vision and preferably not too bulky or expensive.

I intend to use it as the sensor for a "robot" which sits on a table in the living room of people to help them through rehabilitation exercises. For now, the focus is on the movements of arms (I'll mainly be wanting to retrieve bodypose information on the upper body).

I was thinking about using the Oak-D-Lite, but there are so many options out there! What are your thoughts?

Also, small secondary question: I was thinking of using BlazePose for estimating the bodypose, but will using a depth camera really improve its depth estimation or do they not work together in that way? Should I maybe consider using something else for this?

In any case, thank you in advance for your response!

Seems like either Oak-D Lite or Oak-D (wide) are your best choices if you want depth.

Depth is only inferred when using depth-less camera, so you don't get the real positions of the object. If you have access to depth as well, then you can get the true position which improves the robustness of the system in case of occlusions.

Thanks,
