Solution Overview

Problem

The existing methods for virtual reality image processing result in increased data transmission amounts, leading to network congestion and transmission delays due to the need to copy and transmit identical left and right eye image data.

Innovation Solution

A data processing method and apparatus that decodes received image data to obtain a planar image, acquires field of view information to generate synchronized left and right eye images, and displays a virtual reality image, reducing the need for duplicate data transmission by processing the images at the VR device end.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If left eye and right eye image data are copied and transmitted separately, then stereoscopic display effect is achieved, but data transmission amount increases causing network congestion and transmission delay

Engineering Contradiction:

Improvestereoscopic display effectVSAvoiddata transmission amount

Core Design Contradiction:

ReliabilityVSQuantity of substance

Solution Approach 1:

The patent merges the transmission of left eye and right eye image data into a single planar image transmission. Instead of transmitting two separate image streams, the system transmits one planar image that contains all necessary information, and performs view separation at the receiving end through image processing algorithms.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The patent inverts the traditional processing approach by performing image decoding and view separation at the receiving end (VR device) rather than at the transmitting end. The transmitting end only needs to encode and send the planar image, while the receiving end handles the complex processing of generating left and right eye images from the planar image.

Inventive Principle:

Principle #13The other way round (Inversion)

2Loss of information

If duplicate image data is transmitted for left and right eyes, then complete image information is provided, but network bandwidth pressure increases

Engineering Contradiction:

Improveimage information completenessVSAvoidnetwork bandwidth efficiency

Core Design Contradiction:

Loss of informationVSProductivity

Solution Approach 1:

The patent uses virtual copying instead of physical data duplication. A single planar image is transmitted, and the receiving end creates virtual copies of the image data for left and right eye views through computational processing, eliminating the need to transmit actual duplicate data streams.

Inventive Principle:

Principle #26Copying

AI summary

The present disclosure relates to a data processing method, an apparatus, and an electronic device, which relates to the technical field of data processing. The method comprises: a VR device decodes received image data to obtain a planar image to be processed; first acquiring field of view information of a user; then generating, according to the field of view information and the planar image, a left eye image and a right eye image at a same timestamp; and displaying a virtual reality image according to the left eye image and the right eye image at the same timestamp. The present disclosure can reduce the amount of transmitted data by half, reduce the pressure on network bandwidth by half, reduce the situation of network congestion, and correspondingly reduce the transmission delay. The simplified processing procedures result in no problem of asynchronous transmission between the left eye and the right eye.
