1. A computer-implemented method, comprising:
running an initial network on a plurality of images to detect actors pictured therein and body joints of the detected actors;
running fully-connected networks in parallel, one fully-connected network for each of the detected actors, to reconstruct complete three-dimensional poses of the actors;
performing sequential model fitting on the plurality of images, wherein the sequential model fitting is based on results of running the initial network and the fully-connected networks;
determining, based on the sequential model fitting, a locational position for a camera in which the camera has a view of a possible point of collision of two or more of the actors; and
instructing the camera to be positioned in the locational position.
