Abstract

There are several benefits of using a light field display over a traditional HMD; in particular the light field can avoid the vergence-accommodation conflict and can also correct for near- and farsightedness. By rendering only four corner cameras of a subimage array, then these four views can be interpolated in order to create all subimages of the light field. We implement the interpolation of the subimages in the light field with the use of pixel reprojection, while maintaining correct perspective and shading. We give an comprehensive explanation of the construction and calibration of a head mounted light field display, and finally we evaluate the image quality through image difference and conduct a user evaluation of the light field images in order to evaluate if users are able to perceive a difference in the light field images created with the full array of virtual cameras and our method using four cameras and pixel reprojection. In most cases the users were unable to distinguish the images, and we conclude that pixel reprojection is a feasible method for rendering light fields as far as quality is concerned.
