3 results about "Volumetric display" patented technology

A method and system for generating a 3D volumetric image. The method and system comprise rotating about a rotation axis a light modulating surface comprising separately controllable light modulating regions located across the light modulating surface and controlling separately the modulation of the light modulating regions to generate the 3D volumetric image upon rotation of the light modulating surface about the rotation axis. A characteristic of two or more selected light modulating regions of the light modulating surface is then varied in accordance with respective spacings of the two or more selected light modulating regions from the rotation axis.

An aerial-floating three-dimensional volumetric display apparatus, comprising: a three-dimensional display screen (100), which is used for using light-field three-dimensional imaging technology to display three-dimensional content; and a retroreflective imaging panel (200), wherein the three-dimensional display screen (100) is obliquely arranged, reconstructed light rays pass through the retroreflective imaging panel (200) and then reconstruct a three-dimensional light field in mid-air, so as to realize the floating display of three-dimensional content, and the retroreflective imaging panel (200) comprises optical waveguides that are alternately arranged, so as to form a plurality of optical channels for the exit of the reconstructed light rays. The optical waveguides are arranged on the basis of preset dimensions, or the three-dimensional display screen (100) emits the reconstructed light rays on the basis of a preset angle, such that the reconstructed light rays are controlled to be reflected only a specified number of times in each optical waveguide. Thus, the generation of ghost images is fundamentally prevented, and after ghost images are eliminated, floating 3D display technology achieves better visual effects and enhanced clarity.

A system for visualization includes a camera rig having a plurality of cameras that capture images from one or more perspectives; and at least two visual guides defining a volumetric space within an environment that may be physical, virtual, and / or a hybrid of the two and associated with the camera rig. The volumetric space is updated based on changes to one or more parameters associated with camera rig, manually, automatically, and / or in real-time.
