In this paper, we propose a depth‐enhanced integral imaging display based on bifocal lens array. The bifocal lens array consists of a small lens array with plano‐convex circular lens units and a large lens array with square lens units. The proposed display device generates two central depth planes and stitches two reconstructed 3‐D images in depth, which largely improves the depth of field. The experimental results indicate that the proposed structure reconstructed 3‐D image with the depth of field as large as 150.8 mm, which is double of conventional integral imaging display.

“…In surgical operation scenarios, doctors can see the patient's status information during the operation, and assistants can check other information meanwhile. On the other hand, three-dimensional (3D) display which includes holographic display [7]- [10], volumetric display [11], super multi-view display [12], light field display [13], [14], and integral imaging [15]- [17] brings a vivid visual experience to the audiences, and has become an important part of the display technologies. Integral imaging, as one of the most promising 3D display technologies, has the advantages of full and smooth parallax, and visual fatigue free [18]- [21].…”

In this paper, a dual-view integral imaging system is proposed to present two different 3D images for viewers in different viewing zones. For most of the conventional dual-view integral imaging systems, either the viewing angle or the spatial resolution of 3D image is decreased. In the proposed dual-view system, the viewing angle of each viewing zone is enlarged by introducing a switchable mask. Meanwhile, the spatial resolution of the 3D image is maintained by using the time-division multiplexing technology. A prototype of the proposed dual-view system is developed and it has wide viewing angle and high spatial resolution. The experiments coincide with the theoretical analysis.

“…The integral 3-D method requires no special glasses to view 3-D images and provides both vertical and horizontal disparity. Integral 3-D imaging is used in a wide range of applications, such as 3-D movie displays, 2,3 extraction and tracking of objects, 4,5 conversion of images into holograms, [6][7][8] refocusing, [9][10][11][12][13] and user interfaces. 14 In the display stage of the integral 3-D method, a 3-D image is generated using a lens array to reconstruct light rays.…”

Capturing method for integral three-dimensional imaging using multiviewpoint robotic cameras

et al. 2018

Integral three-dimensional (3-D) technology for next-generation 3-D television must be able to capture dynamic moving subjects with pan, tilt, and zoom camerawork as good as in current TV program production. We propose a capturing method for integral 3-D imaging using multiviewpoint robotic cameras. The cameras are controlled through a cooperative synchronous system composed of a master camera controlled by a camera operator and other reference cameras that are utilized for 3-D reconstruction. When the operator captures a subject using the master camera, the region reproduced by the integral 3-D display is regulated in real space according to the subject's position and view angle of the master camera. Using the cooperative control function, the reference cameras can capture images at the narrowest view angle that does not lose any part of the object region, thereby maximizing the resolution of the image. 3-D models are reconstructed by estimating the depth from complementary multiviewpoint images captured by robotic cameras arranged in a two-dimensional array. The model is converted into elemental images to generate the integral 3-D images. In experiments, we reconstructed integral 3-D images of karate players and confirmed that the proposed method satisfied the above requirements.
