摘要
Disclosed are a method for constructing a walking information database, and an apparatus and a method for guiding walking using the walking information database. According to one aspect of the present invention, there is an apparatus for guiding walking using a walking information database which includes: a feature point extracting unit for extracting a feature point from obtained images; a corresponding point detecting unit for detecting a corresponding point based on a corresponding relation between the feature points extracted from continuous images; a current location and walking direction calculating unit for calculating the three-dimensional position and posture of a camera between the images by using the relation between a camera inner parameter and the corresponding point to calculate a current location and a walking direction of a walker; a guiding information generating unit for generating guiding information according to the current location and walking direction of the walker with reference to the walking information database; and a guidance audio source reproducing unit for reproducing a guidance audio source corresponding to the guiding information stereoscopically based on the current location and walking direction of the walker.
