we want to do blobtracking within an opaque dome that has a diameter of 15m, so lets say effective tracking area is a circle with d = 10m. In the middle the dome is separated by a wall, that reaches to the top. I would go for infrared cameras up high, one for each room. Is this still the way to go, or would you recommend some other tech? Multiple Laser scanners are too expensive since we would need 2-4 per area (many people).
