Method and apparatus for presenting image for virtual reality device, device and non-transitory computer-readable storage medium

An apparatus for presenting image for a VR device, comprising:

• an acquisition module, configured to acquire input image data;
• a processing module, configured to establish a correspondence between the input image data and output image data in a polar coordinate system, and obtain, in the polar coordinate system, image data to be presented in the polar coordinate system according to the output image data, the polar coordinate system having a pole which is an intersection of a center of a field of view of the VR device and a display plane;
• and
• a presentation module, configured to present the image data to be presented on the basis of a convex lens.

A device for presenting image for a VR device, comprising a processor and a memory for storing a computer program executable by the processor, wherein the computer program, when executed by the processor, causes the processor to perform a method comprising steps of:

• acquiring input image data;
• establishing a correspondence between the input image data and output image data in a polar coordinate system, the polar coordinate system having a pole which is an intersection of a center of a field of view of the VR device and a display plane;
• obtaining, in the polar coordinate system, image data to be presented in the polar coordinate system according to the output image data;
• and
• presenting the image data to be presented on the basis of a convex lens.
