Abstract

A light-field capture apparatus is provided that includes a camera housing having a plurality of cameras, each camera providing a different viewpoint of a scene. The apparatus may also include a drop-string mechanism coupled to a top portion of the camera housing and a rotary table pivotably coupled to a portion of the camera housing different than the top portion. The drop-string mechanism includes a string having a first end coupled to the top portion of the camera housing and a second end wound around a center column. The rotary table is rotatable around a center column to change horizontal positions of the camera housing. Additionally, rotating the rotary table causes the string of the drop-string mechanism to unwind around the center column in response to changes in horizontal positions of the camera housing, thereby causing a vertical drop in position of the camera housing.
