Multiple Orthographic Frustum Combing for Real-Time Computer-Generated Integral Imaging System

Review on tabletop true 3D display

“…This system has a viewing angle about twice as wide as that of the conventional one. Adopting this prototype, a real‐time EIA generation method, which only needs a single rendering procedure of the 3D scene to generate an EIA, can achieve 65 frames per second with a resolution of 3840 × 2160 and 8 × 8 viewpoints . To accelerate the practicability of the system, super‐resolution convolutional neural network technology is used to achieve 3D display for real scenes …”

“…In addition, plenty of studies can offer optimization strategies to the integral imaging tabletop 3D display, such as increasing the viewing zone, 8,9,68 reducing the crosstalk, 10,11 and improving the rendering efficiency. [12][13][14][15]69 Among them, a viewing-angle-enhanced integral imaging system can achieve a super wide viewing angle of 120°by using tracking techniques. 8 This system has a viewing angle about twice as wide as that of the conventional one.…”

“…Integral imaging uses a lens array to capture both spatial and directional information of the light rays into element images. Innovatively, through the modulation of the lens array, the recorded light field can be reconstructed by the element images . Another light‐ray reconstruction–based 3D display is volumetric 3D display.…”

“…Innovatively, through the modulation of the lens array, the recorded light field can be reconstructed by the element images. [7][8][9][10][11][12][13][14][15] Another light-ray reconstruction-based 3D display is volumetric 3D display. Different from projection-based light field and integral imaging, the volumetric 3D display system arranges light spots called "voxel" in a volume to form a 3D object by scanning the 3D space with a light spot or a 2D image; subsequently, the viewers can directly perceive space position (X, Y, Z) and obtain a good visual perception.…”

Multiple elemental image mapping for resolution-enhanced orthographic view image generation based on integral imaging

“…In the integral imaging display, the 3D information of an object is transferred to an elemental image array by using a micro‐lens array . The elemental images are recorded by a pickup device such as a charge coupled device or obtained by computer‐generated integral imaging . Therefore, 3D information of the object can be manipulated by utilizing the elemental images.…”
