Abstract

An estimate image generating unit (26) generates an estimate image corresponding to estimate values of a position and an angle of a camera (10) stored in a position and angle information storing unit (25), and stores the estimate image into an estimate image storing unit (27). A collating unit (28) collates an estimate image with a scenery image, and corrects estimate values of a position and angles of the camera (10) according to a result of the collation. An indication image generating unit (29) generates an indication image by processing indication information stored in an indication information storing unit (23), based on position information that shows a position of the camera (10) and angle information that shows angles of the camera (10) after the correction processing stored in a position and angle information storing unit (25).

Dependent claims

A video navigation apparatus comprising:

a photographing unit that photographs a scene;
an estimating unit that estimates a position and angles of the photographing unit;
an estimate image generating unit that generates an estimate image corresponding to estimate values of a position and angles of the photographing unit estimated by the estimating unit;
a collating unit that collates an estimate image generated by the estimate image generating unit with a scenery image photographed by the photographing unit, and corrects an estimate value estimated by the estimating unit according to a result of the collation;
an indication image generating unit that generates an indication image by processing indication information indicated in advance based on position information that shows a position of the photographing unit and angle information that shows angles of the photographing unit after correction processing by the collating unit;
and
a display unit that displays an indication image generated by the indication image generating unit.
