A glasses-free random dot stereoacuity test using a multi-view display system

Abstract

In this paper, we propose a glasses-free random dot stereoacuity test using a multi-view display system. We use a multiview display system with a liquid crystal display panel and a parallax barrier. We generate the random dot base images with different disparities. The multi-view system and the generated base images provide several random dot stereotest images to the patient. The proposed method can offer not only binocular disparity but also motion parallax. We implement 4-view parallax barrier system with a 5K liquid crystal display monitor, and generate the random dot base images for the system. For the practical usage, we also develop graphical user interface of the stereoacuity test which contains the personal calibration function in pixel unit.
