Embodiment Construction

[0034] There have been some efforts to solve the vergence accommodation conflict (VAC) problem, among which is the integrated imaging (InI-based) light field 3D (LF-3D) display. Integrated imaging generally refers to three-dimensional imaging techniques that capture and reproduce light fields by using two-dimensional arrays of optical apertures or microlenses. This configuration allows the reconstruction of a 3D scene by rendering directional rays apparently emitted by the scene seen from a predesigned viewing window via the array optics. However, there is a lack of system design methods suitable for optimizing 3D display systems, including InI-based LF-3D head-mounted displays (HMDs). Therefore, designing high-performance 3D display systems remains a challenge. In particular, without an optimized design, the InI-HMD will not be able to correctly render the depth and adjustment cues of the reconstructed 3D scene, resulting in compromised image quality and comfort.

Abstract

Methods and frames for designing and optimizing high performance light field displays, such as integrated imaging head mounted displays, are disclosed. The disclosed techniques enable user-defined metrics to characterize the performance and optimization of such systems. A design method relates to an integrated imaging-based three-dimensional (3D) display system comprising an array optical body, an array display device for generating a plurality of element images, a first reference plane representing a virtual central depth plane (CDP), a second reference plane representing a viewing window for viewing a reconstructed 3D scene, and an optical sub-section representing a human eye model. The method includes tracing rays starting from the array display device, passing through the array optical body and reaching the optical sub-section for each element of the array display device and the array optical body, and adjusting one or more parameters to obtain at least a first metric value within a predetermined value.
