Abstract

The present disclosure provides a method and apparatus for spatial localization. The method includes: capturing a first image of a second device, the first image includes 2D points of the second device and descriptors corresponding to the 2D points; performing feature point matching between the 2D points and 3D points on a 3D model of the second device, to obtain a first correspondence between at least three non-collinear 2D points and the 3D points on the 3D model of the second device, the 3D model of the second device includes the 3D points and descriptors corresponding to the 3D points; determining a localization of the 3D model of the second device in a world coordinate system according to the localization of the second device and a second correspondence between the second device and the 3D model; and determining the pose of the first device in the world coordinate system.
