Abstract:
Embodiments of the present disclosure disclose a method and an apparatus for determining a planar surface. A specific embodiment of the method comprises: determining, from obtained images of the environment that include a to-be-determined planar surface, feature points belonging to the to-be-determined planar surface; judging whether the number of the feature points belonging to the to-be-determined planar surface is smaller than a preset number threshold; if yes, generating first prompt information for prompting a user to add feature points on the to-be-determined planar surface; obtaining at least two first images including the added feature points; and in response to the number of the feature points belonging to the to-be-determined planar surface in the first images being no less than the preset number threshold, reconstructing the to-be-determined planar surface based on the first images so as to determine a location and an orientation of the to-be-determined planar surface. This embodiment implements reconstruction of a weakly-textured or texture-less planar surface.

Claim (Index 13):
The device according to  claim 11 , wherein before determining, from obtained images of the environment that include a to-be-determined planar surface, feature points belonging to the to-be-determined planar surface, the one or more processors are further configured for,\n obtaining the images of the environment, wherein at least two of the obtained images of the environment includes the to-be-determined planar surface; performing three-dimensional reconstruction of the environment including the to-be-determined planar surface based on the obtained images so as to generate a three-dimensional point set of the environment; and in response to the number of feature points belonging to the to-be-determined planar surface in the first images being no less than the preset number threshold, reconstructing the to-be-determined planar surface based on the first images so as to determine a position and an orientation of the to-be-determined planar surface in the three-dimensional environment.
