Abstract: A method for processing display data comprises: the host divides the display area into a central area and an edge area according to the field of view of a head-mounted display; segments each frame of the display data into first display data corresponding to the central area and second display data corresponding to the edge area; processes the first display data and the second display data according to a first transmission factor and a second transmission factor to obtain first transmission data and second transmission data and sends them to the head-mounted display; and the head-mounted display performs image reconstruction to the received first transmission data and second transmission data, to obtain the displayed image corresponding to the frame of display data, and outputs and display it.

Abstract: A binocular vision localization method, device and system are provided. The method includes calculating first pose change information according to two frames of images collected by a binocular camera unit at two consecutive moments and calculating second pose change information according to inertia parameters collected by an inertial measurement unit between the two consecutive moments. Matched feature points in the two frames are extracted from the two frames respectively. A reprojection error of each feature point is calculated. The calculations are taken as nodes or edges of a general graph optimization algorithm to acquire optimized third pose change information for localization. The system includes a binocular vision localization device, and a binocular camera unit and an inertial measurement unit respectively connected thereto, a left-eye camera and a right-eye camera are symmetrically located on two sides of the inertial measurement unit. This can improve accuracy and real-time performance for pose estimation.
