Program Description:

This design uses an Omnivision OVM7690 640x480 CMOS CameraCube module,
a laser diode, and a Parallax Propeller microcontroller to create a 
low-cost laser range finder. Distance to a targeted object is calculated 
using triangulation by simple trigonometry between the centroid of laser 
light, camera, and object.
