US 10,852,821 B2 · Virtual ray tracing method and dynamic light field refocusing display system

Abstract

The present invention relates to a virtual ray tracing method and dynamic light field refocusing display system, ray information collection, or random retrieval for pixels on a full focus image, so as to reduce ray collection total; and/or simplifying cross point retrieval where an object surface is regarded smooth. The system includes a virtual reality content processor, a virtual reality monitor, an eyeball tracker, an eyeball tracing processor, and a ray refocusing processor. The present invention reduces computational complexity, enables automatic replacement of erroneous sampling, causes to achieve real and accurate refocusing. The present invention may enable dynamic refocusing along a gazing direction of the human eye, and enable focusing by a user to objects of variable distance, to be consistent with viewing characteristics of the human eye.

Dependent claims

A virtual reality dynamic light field refocusing display system, comprising:

a virtual reality content processor;
a virtual reality monitor;
an eyeball tracker to monitor eyeball movement direction by sampling real time images containing only eyeballs;
an eyeball tracing processor;
and
a light field refocusing processor to process dynamic light field refocusing,
wherein the virtual reality content processor is in data-line connection with at least one of the virtual reality monitor, the eyeball tracker, the eyeball tracing processor, and the light field refocusing processor;
wherein the virtual reality dynamic light field refocusing display system is utilized for a virtual reality helmet.

5 more elements

A virtual ray tracing method, comprising:

obtaining a depth map of a full focus image;
retrieving ray information where fewer than all pixels of the full focus image are located which correspond to fewer than all rays sampled;
and
performing color fusion based on the ray information to obtain an end display result;
wherein the step of retrieving ray information comprises vibration collection, where a ray loop is divided into a number of grids, and then one pixel is located from each of the grids and corresponding ray information of the one pixel is retrieved.
