摘要： A method displays a binocular hologram image. The method includes generating a light beam of an incident wave field having coherence, expanding the generated light beam to the size of the active area of a display, converging the expanded light beam on the respective positions of the eyes of a user, generating digital hologram content, and displaying a hologram image based on the converged light beam and on the digital hologram content.

摘要： A head-up display system for a vehicle includes a head-up display apparatus and an occupant monitoring apparatus. The head-up display apparatus includes a projection device configured to project a three-dimensional image in front of an occupant of the vehicle. The head-up display apparatus is configured to project a projection image with respect to an object present outside of the vehicle. The occupant monitoring apparatus includes an imaging device configured to capture an image of the occupant. The occupant monitoring apparatus is configured to generate personal data related to a sense of sight of the occupant on the basis of the captured image of the occupant. The head-up display apparatus is configured to adjust the projection image in the three-dimensional image on the basis of the personal data generated by the occupant monitoring apparatus, and project, from the projection device, the three-dimensional image in which the projection image is adjusted.

摘要： Pointers are added to a 3D volumetric dataset to help the user visualize the direction of blood flow. A 3D volume containing at least one blood vessel is created. Next, the direction of the blood flow is determined. Next, at least pointer is placed into the 3D volume in an aligned fashion with the direction of blood flow such that the 3D volume is modified. Next, the modified 3D volume is displayed on a head display unit, such as an augmented reality or virtual reality display. Next, at least one pointer is advanced to a new position for additional modification of the 3D imaging volume.

摘要： Improvements in a 3D target shooting training glasses and target. The 3D target, shooting glasses and training system that allows starting shooters and experienced shooters to improve their skills and accuracy. The paper targets are printed with offset colors that create a 3D image when viewed through 3D glasses. The offset is typically filtered for a red color and a blue color to provide a depth to the image. Shooting glasses are used with each lens providing a color filter to allow a 3D printed target depth perception and sighting training through a dominant eye. The 3D target shooting training glasses and target to provide a training system that allows a user to identify a dominant eye and use the glasses and 3D printed image to aim using the dominant eye on the target while maintaining peripheral vision.

摘要： A three-dimensional display method is provided and comprises: acquiring target space coordinates of a target marker in a physical space; converting the target space coordinates into rendering coordinates in a virtual space; acquiring data of a virtual object to be displayed, and rendering, based on the data of the virtual object and the rendering coordinates, the virtual object to obtain a left-eye display content and a right-eye display content of the virtual object; and displaying the left-eye display content and the right-eye display content. The left-eye display content is projected onto a first optical lens, the right-eye display content is projected onto a second optical lens, and the first optical lens and the second optical lens respectively reflect the left-eye display content and the right-eye display content to human eyes. The method can achieve alignment display of the virtual object with the target marker, and a stereoscopic display.

摘要： Some implementations of the disclosure are directed to tessellating a light field into a size or depth that is larger or further extended than the pupil size of an imaging system or display system. In some implementations, a display system comprises: a display configured to emit light corresponding to an image; a first optical component positioned in front of the display, the first optical component configured to pass the light to an orthogonal field evolving cavity (OFEC) at a plurality of different angles; the OFEC, wherein the OFEC comprises a plurality of reflectors that are configured to reflect the light passed at the plurality of different angles to tessellate the size of the image to form a tessellated image; and a second optical component optically coupled to the OFEC, the second optical component configured to relay the tessellated image through an exit pupil of the display system.
