The research of the stereoscopic characteristics of virtual reality helmets

Individual stereoscopic virtual reality devices have become very popular all over the world. Their advantages in comparison with traditional means of presenting stereo images are to provide a large viewing angle, taking into account the location and movement of the observer, binding the image to the direction of his gaze. To obtain a high-quality and com-fortable visualization system, it is necessary to achieve a certain ratio of technical parameters. In this paper, we consider the limitations of the depth of a three-dimensional image repro-duced in helmets of virtual and augmented reality, due to the stereoscopic nature of its for-mation. Methods and results of the estimated calculations of the boundary distances for dif-ferent conditions for the demonstration of three-dimensional stereoscopic images are given. Experimental studies of the overall parameters of optical circuits of seven different types of virtual reality helmets have been carried out. It is shown that most of them, especially the most accessible as cheaper and often used in a social environment, are not suitable for demonstrating deep scenes of the surrounding visual environment. Recommendations for their modernization are given. © 2020 National Research Nuclear University. All rights reserved.
