Method and apparatus for determining a planar surface

An electronic device, comprising:

• an image acquiring apparatus for acquiring images;
• one or more processors;
• and
• a memory for storing one or more programs which, when being executed by the one or more processors, cause the one or more processors to implement the method comprising:
• 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;
• generating, in response to that the number of the feature points belonging to the to-be-determined planar surface is smaller than a preset number threshold, 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 position and an orientation of the to-be-determined planar surface.

A non-transitory computer-readable storage medium on which a computer program is stored, wherein the program, when being executed, implements the method comprising:

• 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;
• generating, in response to that the number of the feature points belonging to the to-be-determined planar surface is smaller than a preset number threshold, 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 position and an orientation of the to-be-determined planar surface.
