Abstract

A method and apparatus for spatial locating. The method includes: acquiring feature area information and a current image captured by a camera (); searching the current image for a feature area of an interactive device based on the feature area information, to determine position information, the position information being used to indicate the position of the feature area in the current image (); determining first pose information associated with the position and attitude of the feature area relative to the camera () based on the position information; calculating a re-projection error of the feature area in the current image () based on the feature area information and the first pose information; and if the re-projection error is less than or equal to a preset threshold, determining current pose information associated with the position and attitude of the interactive device currently in a global coordinate system () based on the first pose information.
