Abstract

The invention provides an anti-distortion processing method for images, an anti-distortion processing device for images and a computer readable storage medium. The method comprises the steps of: calculating original coordinate distances and original pixel distances from to-be-rendered pixel points to a central point; referring to an anti-distortion ratio table according to the original pixel distances and acquiring anti-distortion ratios corresponding to the original pixel distances; performing calculation according to the original coordinate distances and the anti-distortion ratios to acquirecorrection coordinate values of the pixel points. The method is simple to implement; anti-distortion processing can be achieved only by presetting an anti-distortion ratio table and performing simpleoperation and table query operation; the method is suitable for anti-distortion processing of all lenses; the values of the anti-distortion ratio table are the anti-distortion ratios of pixel pointswhich are the same distance away from the central point, so that the table is small and can be transmitted easily during rendering of a tinter.

Description

technical field [0001] The invention relates to the technical field of virtual reality, in particular to an image anti-distortion processing method. The invention also relates to an image anti-distortion processing device and a computer-readable storage medium. Background technique [0002] Virtual reality technology comprehensively utilizes computer graphics, photoelectric imaging technology, sensing technology, computer simulation, artificial intelligence and other technologies, and with the help of various interactive devices, it aims to provide users with a realistic and multi-sensory virtual world. In a virtual reality device, a lens is generally used to project an image in a display device into a user's eyes. The lens distortion of the VR head-mounted display can maximize the distortion of the human visual range, present a larger field of view, and enhance the immersion of the experience. Due to the physical characteristics of the edge of the lens itself, when the im...
