Different methods for creation of 3D image files, including integral imaging, 2D + z files and 2D images captured at different view angles, are considered. It is found that the disadvantage of the integral imaging method for capturing is the small depth of the 3D image. It is demonstrated that the capturing an object from different angles using a rotating platform and a conventional camera makes it possible to obtain a higher depth. Large 3D images using Full HD multiprojectors and Ultra HD 4K projector are created. 3D displays based on mobile devices are also developed.
Multiview 3D display system consisting of mobile phone screen and optical screen consisting of microlens array film is designed. 3D image files are created and images are demonstrated based on different smartphones with high resolution displays.
Multiview 3D display system consisting of four full HD projectors and optical screen consisting of microlens array film is designed. Matlab codes for integration of 2D images captured at different angles into one common 3D file are created and 3D images are demonstrated.
In this paper the multi-view 3D display system which includes the modules of capturing three-dimensional objects, image processing (creation of 3D image files) and display screen for the 3D image displaying based on integral imaging technology is developed. Large display screens using multi-projectors are created. Multi-projector system is used for improving the performance, such as viewing resolution, viewing angle, etc. Preliminary experimental results obtained using Full HD multi-projectors are discussed. 3D display based on mobile devices is also developed. 3D image files are created using 2D + depth files and 2D images captured at different view angles. Images on smartphones Sony 4K (resolution 3840 x 2160) and Samsung and LG (resolution 2560 x 1440) are demonstrated.
Glassless multi-view projection display system that combines the modules of capturing three-dimensional objects, image processing (creation of 3D files) and display screen with a holographic diffuser is presented. Optical simulations of lenticular and two-dimensional microlens arrays are performed with the aim to determine optimal lenticular sheets, view angle, view number, depth, etc. Effects of crosstalk and ghost-imaging are studied both numerically and experimentally. Multi-projector system is designed and 3D images on 30-inch screen are demonstrated.
Beam combiners and splitters based on the frustrated total internal reflection, diffraction and refraction effects of light beams are considered. New high efficiency prismatic beam combiner consisting of uniform material is proposed.
