METHOD OF CONSTRUCTING STREET GUIDANCE INFORMATION DATABASE, AND STREET GUIDANCE APPARATUS AND METHOD USING STREET GUIDANCE INFORMATION DATABASE

摘要

A walking guidance apparatus using a walking guidance information database includes a feature point extracting unit configured to extract a feature point from an acquired image, a corresponding point search unit configured to search for a corresponding point based on a correspondence relationship between feature points extracted from consecutive images, a current position and walking direction calculation unit configured to calculate a current position and a walking direction of a pedestrian by calculating a 3D position and pose of a camera between the images by using camera internal parameters and a relationship between corresponding points, a guidance information generating unit configured to generate guidance information according to the current position and the walking direction of the pedestrian, and a guidance sound source reproducing unit configured to reproduce a guidance sound source corresponding to the guidance information in 3D based on the current position and the walking direction of the pedestrian.

1. A walking guidance apparatus using a walking guidance information database, the walking guidance apparatus comprising:
a feature point extracting unit configured to extract a feature point from an acquired image; a corresponding point search unit configured to search for a corresponding point based on a correspondence relationship between feature points extracted from consecutive images; a current position and walking direction calculation unit configured to calculate a current position and a walking direction of a pedestrian by calculating a three-dimensional (3D) position and pose of a camera between the images by using camera internal parameters and a relationship between corresponding points; a guidance information generating unit configured to generate guidance information according to the current position and the walking direction of the pedestrian by referring to the walking guidance information database; and a guidance sound source reproducing unit configured to reproduce a guidance sound source corresponding to the guidance information in three dimensions based on the current position and the walking direction of the pedestrian.
