The invention belongs to the fields of optical imaging and mechanical manufacturing, and particularly relates to an optical field imaging device of a stacked type video camera array structure. The imaging device comprises a supporting part and a plurality of video cameras; the supporting part consists of a pedestal and a plurality of supporting rods; the video cameras are arranged on the supporting rods in a fixed mounting mode; the video cameras with the same quantity are arranged on each supporting rod; on a vertical plane, the video camera on the same supporting rods are configured sequentially from top to bottom by different pitch angles; on a horizontal plane, the video cameras on different supporting rods and positioned at equal altitude are configured sequentially from left to right by different azimuth angles. Basic conditions are provided for acquisition of space optical field information through multiple imaging at space points; moreover, necessary conditions are provided for splicing acquisition of space scene information of a larger view field through view extension of the adjacent video cameras. The imaging device has a simple structure and low cost, and is easy to implement and popularize.
