TLDR: In this paper, a large-depth-of-field true-3D augmented reality display method and system is proposed, where an information display module group formed by a micro display device and a lens array is irradiated by a plurality of point light sources and a virtual true 3D image is obtained in 3D space.

Abstract: The invention discloses a large-depth-of-field true three-dimensional augmented reality display method and system. An information display module group formed by a micro display device and a lens arrayis irradiated by a plurality of point light sources and a virtual true three-dimensional image is obtained in three-dimensional space; and information of the virtual true three-dimensional image is superposed to a realistic objective environment by the information display module group to realize true three-dimensional augmented reality displaying. The micro display device is not arranged at a doubled focal length of the lens array and the superposition depths of the virtual true three-dimensional image are different under point light source irradiation at different positions. Therefore, problems that the depth of field of the image is limited in the current augmented reality display system, a conflict between the focusing of an observer and a convergence competition exists in the currentaugmented reality display system and the depth-of-field control mechanism is complicated and the response speed is low of the current augmented reality display system can be solved; and thus real-time-response 3D image augmented reality displaying of the large-depth-of-field true three-dimensional image is realized.
