Three dimensional mapping

A memory device storing instructions that, when executed, cause a processor to perform a method comprising:

• generating a three dimensional map of a physical space, including:
• capturing an image sequence of a plurality of physical surfaces via an image capture device;
• tracking a plurality of feature points between individual images in the image sequence based on a projected light pattern situated to create a consistent artificial texture pattern on the plurality of physical surfaces;
• and
• generating the three dimensional map of the plurality of physical surfaces based on the image sequence and the plurality of feature points.

An apparatus comprising:

• a processor configured to execute a three dimensional mapping operation, including:
• capture an image sequence of a plurality of physical surfaces via an image capture device;
• receive a user input corresponding to the image sequence, the user input identifying a location of a surface edge from the plurality of physical surfaces by placing an indicator of the location of the surface edge in the image sequence;
• track a plurality of feature points between individual images in the image sequence based on a projected light pattern situated to create a consistent artificial texture pattern on the plurality of physical surfaces;
• and
• generate a three dimensional map of the plurality of physical surfaces based on the image sequence, the user input, and the plurality of feature points.
