1. A method of adjusting motion capture using a distance of two or more objects in a 3D monitored space, the method including: identifying from images captured by one or more cameras, first and second objects present in a 3D monitored space, wherein the first and second objects are at least partially within fields of view of the one or more cameras; repeatedly calculating spatial coordinates for the first and second objects present in the 3D monitored space based upon the images captured by the one or more cameras and calculating a calculated distance between the first and second objects in space from the spatial coordinates; and responsive to the calculated distance, adjusting at least one parameter of motion capture; whereby adjusting the at least one parameter of motion capture enables capturing additional images of the first and second objects moving in space.
