1. A system for capturing live action three-dimensional video comprising: a first and a second camera, making up a stereo camera pair, the first and second stereo cameras each having known imaging parameters such that a depth-from-stereo algorithm may be applied to corresponding sets of images captured using the stereo camera pair to generate three-dimensional camera data for a three-dimensional space viewed by the stereo camera pair; a LIDAR, having a known position relative to the stereo camera pair, configured to produce three-dimensional LIDAR data; and a controller configured to use the depth-from-stereo algorithm to generate the three-dimensional camera data for the three-dimensional space, and combine the three-dimensional camera data and the three-dimensional LIDAR data, with the three-dimensional LIDAR data taking precedence over the three-dimensional camera data to thereby generate three-dimensional data corresponding to the three-dimensional space.
