An XR positioning-based rolling shutter image motion compensation method and system

Abstract

The present application relates to a kind of based on XR positioning's rolling shutter image motion compensation method and system, belong to image processing technical field, solve the existing rolling shutter image motion compensation incomplete and the problem of low computing efficiency. Including: the binocular rolling shutter image and device pose of real-time acquisition are obtained, device pose is cached to positioning data queue;Based on positioning data queue, the row block strategy of each frame binocular rolling shutter image is obtained, then each rolling shutter image is divided into multiple row blocks, and the exposure time of each row block is calculated, and the relative pose of each row block relative to reference row block;Based on the calibration parameters and distortion model of XR device, de-distortion processing, motion compensation based on its relative pose and re-impose distortion processing are sequentially executed for each row block;All row blocks after processing are combined according to its order in rolling shutter image, to generate the binocular rolling shutter image after motion compensation. The improvement of motion compensation effect and computing efficiency is realized.
