Dual laser distance measurer with midpoint locating feature

A method for locating a midpoint between a first surface and a second surface, comprising:

• directing a first laser beam toward the first surface and a second laser beam toward the second surface, wherein the first and second laser beams are emitted in opposite directions from a laser distance measurer;
• independently receiving, at the laser distance measurer, laser light reflected from the first and second surfaces;
• determining a first distance from the laser distance measurer to the first surface and a second distance from the laser distance measurer to the second surface;
• and
• indicating a position of the laser distance measurer relative to the midpoint between the first and second surfaces based on the first and second distances.

A method for performing a segmentation process, comprising:

• determining one or more target positions between a first surface and a second surface;
• directing a first laser beam toward the first surface and a second laser beam toward the second surface, wherein the first and second laser beams are emitted in opposite directions from a laser distance measurer;
• independently receiving, at the laser distance measurer, laser light reflected from the first and second surfaces;
• determining a first distance from the laser distance measurer to the first surface and a second distance from the laser distance measurer to the second surface;
• and
• indicating a position of the laser distance measurer relative to a first target position between the first surface and the second surface based on the first and second distances, the first target position being between a first segment out of a plurality of continuous equal segments and a second segment out of the plurality of continuous equal segments, the second segment being adjacent to the first segment, and the plurality of continuous equal segments being the sum of the first distance and the second distance.
