A computing device and method are provided for transmitting a relevant subset of map data, called a neighborhood, to enable mutual spatial understanding by multiple display devices around a target virtual location to display a shared hologram in the same exact location in the physical environment at the same moment in time. The computing device may comprise a processor, a memory operatively coupled to the processor, and an anchor transfer program stored in the memory and executed by the processor.

A volumetric display system including a volumetric display for displaying a scene viewable as a three-dimensional floating-in-the-air scene in a display space, enabling a user to reach a first object into the display space, a location determination unit locating real objects in the display space, providing a location of the first object when the first object is inserted into the display space, and a computer for receiving the location of the first object, detecting when the location of the first object is at a location where an object is displayed in the three-dimensional scene, thereby determining that the first object is viewable as touching the displayed object following a detection of the first object viewable as touching the displayed object, producing a new three-dimensional scene displaying the displayed object as if manipulated by the first object. Related apparatus and methods are also described.

Provided are a webserver-based video content production system and method for printing a holographic stereogram photo. According to the webserver-based video content production system and method, an encoding process is performed on image data under a web environment to prevent data loss in a network communication process, and then the encoded image data is transmitted to a webserver. The webserver decodes the encoded image data and performs a second-half task (postprocessing) on the decoded image data using deep learning such that a high-quality hologram photo can be printed within a relatively short time without any unnecessary process.

A holographic projection system, a method and apparatus for processing a holographic projection image, an electronic device, a computer readable storage medium, and a computer program product are provided. The system includes a near field communication information storage, for storing image content configuration information readable a by near field communication mechanism; and a holographic projection body provided with a near field communication scanner, for reading the image content configuration information in the near field communication information memory through the near field communication scanner and presenting a holographic projection corresponding to the image content configuration information.
