Abstract
A method of finding and defining a plane includes screen-space scanning a plurality of rows of a depth image and interpolating a straight depth line through at least two depth values for each row. A pair of straight boundary lines are then fit to the endpoints of the straight depth lines, and a plane is defined to include these straight boundary lines.
Claims19
A method of finding and defining a plane, comprising:
- scanning in screen space a plurality of rows of a depth image;
- identifying a first deepest value in a first region of each row;
- identifying a second deepest value in a second region of each row;
- interpolating a straight depth line through the first deepest value and the second deepest value for each row;
- fitting a first straight boundary line using a subset of first endpoints of the straight depth lines;
- fitting a second straight boundary line using a subset of second endpoints of the straight depth lines;
- and
- defining the plane through the first straight boundary line and the second straight boundary line.

A computing system, comprising:
- a depth camera configured to capture depth information useable to construct a depth image;
- a logic subsystem operatively connected to the depth camera;
- and
- a data-holding subsystem holding instructions executable by the logic subsystem to:
- scan in screen space a plurality of rows of a depth image;
- identify a first deepest value in a first region of each row;
- identify a second deepest value in a second region of each row;
- interpolate a straight depth line through the first deepest value and the second deepest value for each row;
- fit a first straight boundary line using a subset of first endpoints of the straight depth lines;
- fit a second straight boundary line using a subset of second endpoints of the straight depth lines;
- and
- define a plane through the first straight boundary line and the second straight boundary line.
