HI, I been working on interactive installations for public spaces usually i put one camera in the roof pointing to the floor, i always have the problem that i need to have the camera 6 or 7 meters in the roof to track 4 * 4 meters space aproximately and thats a very big limitation since there are a lot of spaces that doesnt allow to put a camera 7 meters up. The thing is that i went to a conference where a guy explained he used 4 cameras to track people in a space instead of just one and you dont need to have a high roof . I would like to know if somebody know this technique for tracking people in spaces with 4 cameras ?
thanks
