Robotic systems using laser based sensors to measure height profiles on target objects house a laser light source and a detector array together in one unit. Such two dimensional laser based reflective range sensor systems project a stripe of laser light onto an object which is then reflected onto the detector array. Imaged laser light on the detector array renders a profile which depicts the relative height (or range) of the object for each lateral position (or resolution) along the laser stripe. Rendered profiles requiring operator inspection in order to identify points of interest on height profiles consume excessive amounts of operator time and are inconsistent and inaccurate.
