FREE VIEWPOINT VIDEO DISPLAY APPARATUS

摘要

An omnidirectional image storage unit stores frames of panoramic image shot while moving on the route, a route information storage unit stores route information indicating nodes and branches on the route, and a correspondence information storage unit stores correspondence between each frame and each point on the route. A data updating unit successively updates a current position and a sight direction based on a user's input. An image cutout unit reads out a panoramic image corresponding to a current position and cuts out a field of view image that constructs a field of vision in a sight direction. A route mapping unit creates a route map indicating a current position and a sight direction superimposed upon a plan view of the route. An image display unit displays the field of view image and the route map side by side.

主权项

1. A free viewpoint video display apparatus for displaying a field of vision in any direction viewed from a viewpoint moving along a predetermined route, comprising:
an omnidirectional image storage unit for storing omnidirectional images, in respective frame units, having fields of vision of 360 degrees shot using an omnidirectional camera while moving along the route; a route information storage unit for storing route information that includes position information indicating positions of a plurality of nodes constructing the route and connection information indicating a branch for a connection between the nodes; a correspondence information storage unit for storing correspondence information indicating correspondence between each individual frame of the omnidirectional images stored in the omnidirectional image storage unit and a node or one point on a branch in the route information stored in the route information storage unit; a current position data storage unit for storing current position data indicating a current position on the route; a line of sight direction data storage unit for storing line of sight direction data indicating a line of sight direction; a data updating unit for performing, based on a user's input operation, a current position update processing for updating the current position data so that the current position moves on the route and a line of sight direction update processing for updating the line of sight direction data so that the line of sight direction changes; an image cutout unit for recognizing a current position frame corresponding to a current position indicated by the current position data by making reference to the correspondence information, and reading out an omnidirectional image of the current position frame from the omnidirectional image storage unit, and cutting out, from a read-out omnidirectional image, a field of view image that constructs a field of vision in a line of sight direction indicated by the line of sight direction data; a route mapping unit for creating, based on the current position data and the line of sight direction data, a route map on which indices indicating a current position and a line of sight direction are superimposed upon a plan view of the route; and an image display unit for displaying side by side the field of view image and the route map.
