Patent attributes
An example method includes receiving a plurality of detected depth points indicative of depths of at least one surface and determining a projection of the detected depth points onto a plane. The method may also include identifying a plurality of first detected points, where a first detected point comprises a first point at a particular location of the plane in the projection. The method may also include storing digital entries corresponding to points located within a threshold buffer from one of the first detected points relative to the plane. The method may additionally include determining values for the digital entries, where a value for a digital entry corresponding to a particular point comprises an accumulation of distances from detected depth points that cross the particular point. The method may further include determining a digital height map representative of heights of the at least one surface relative to the plane.
