The invention designs a naked-eye display system based on 3D vision, and simultaneously, designs a video live-broadcasting device based on the 3D vision naked-eye display system and a UAV 3D vision system based on the 3D vision naked-eye display system. By means of the 3D vision naked-eye display system disclosed by the invention, the 3D vision imaging authenticity and definition are improved; the brightness, the contrast, the colour and the comfort level of a video obtained by 3D vision imaging are effectively improved; furthermore, the 3D vision naked-eye display system is applied to vision experience, and applied in the technical fields of network video live-broadcasting, multi-point live-broadcasting of a scenic area image, high-definition photographing of a UAV and the like; and thus, the user experience is improved.
