Abstract:
Virtual reality (VR) is the most fascinating multimedia solution of recent years. Cave (Cave Automatic Virtual Environment) is the most advanced example of VR installation. The aim of the work is to present an image stitching problem in specific cave installation. The low-budget installation called SEMI-CAVE has been built to study the impact of visual environment on human psychophysiology at the workplace. Six projectors display images on four walls of a relatively large room. Correct stitching of images with perfect geometry is the deciding factor in ensuring good immersion in VR under these conditions. We have developed a special image stitching subsystem working in the SEMI-CAVE solution. The subsystem makes it possible to easily combine individual images to ensure the correct geometry of the displayed content. In addition, the implementation of the stitching subsystem was carried out at the shader level, which ensured the fastest possible technical solution. The work presents su
bsystem assumptions, the method of implementation and conducted tests.
