1. A system for acquiring camera data in a space, comprising: a plurality of cameras disposed in the space; a first plurality of illumination units, wherein each of the first plurality of illumination units is disposed proximal to one of the cameras; a second plurality of illumination units disposed overhead in the space, the second plurality of illumination units being different from the first plurality of illumination units and being disposed independently of the cameras; and a control unit that controls actuation of the illumination units and the cameras, wherein the second plurality of illumination units are controlled independently of the first plurality of illumination units and of the cameras, and wherein the control unit actuates different combinations of the first plurality of illumination units and the second plurality of illumination units to provide a plurality of different lighting views of the space while the cameras acquire the camera data in the space, wherein image features are extracted from the camera data acquired during the actuation of the different combinations of illumination units, wherein the image features are used in analyzing the camera data, and wherein analyzing the camera data includes determining whether fog is present in the space.
