Virtual dynamic field depth change processing method with human eye focusing simulation

Abstract

The invention discloses a virtual dynamic field depth change processing method with human eye focusing simulation. Staring positions of eyeballs of two eyes in a virtual reality scene are obtained; according to the staring positions of eyeballs of two eyes, each frame of image in the virtual reality scene is processed in real time to obtain an expected focusing distance between a virtual staring object and a virtual lens under a current frame; calculation is carried out based on the expected focusing distance and an internal reference parameter of the virtual lens, thereby obtaining a dispersion circle radius; on the basis of the dispersion circle radius, a blurring effect is constructed; and the blurring effect is superposed on a current frame of an original virtual reality scene for displaying, thereby completing field depth change processing. According to the invention, the focusing distance of the user eyes of the head-mounted displays can be monitored dynamically and thus the dispersion circle radius can be calculated in real time; the special blurring effect is added on the original image and thus the depth-of-field effect of object observation by human eyes in real life can be simulated effectively, so that the immersive experience of the user can be improved substantially.

Description

Technical field [0001] The invention relates to a graphic image processing method, in particular to a virtual dynamic depth-of-field change processing method simulating human eye focusing, and is suitable for display screens or virtual reality equipment. Background technique [0002] With the development of hardware technology and software technology, virtual reality head-mounted displays (HMDs) technology has begun to spread to consumers, and has become the preferred device for simulating immersive experiences. In an immersive experience, maximizing the simulation and restoration of the way the human eye observes things in real life is the key to improving the user experience of virtual reality headsets. [0003] In real life, the human eye has a depth of field effect when observing things, that is, only objects within a certain range before and after the focus point can form a clear image in the human eye, and objects that are too far or too close to the focus point of the human ...

Problems solved by technology

However, the existing virtual reality head-mounted display does not provide the function of dynamic depth perception, and the image presented to the human eye is clear regardless of the distance, which greatly reduces the user experience.
