Abstract: A method for generating 3D data of an object using a laser projector uses the steps of calibrating at least two laser projectors to a known coordinate system relative to an object; projecting a first laser beam along a path to a point on the object; placing a reflection target at the point for reflecting the first laser beam for generating a first feedback signal indicative of the first laser beam hitting the reflective target; calculating first vector coordinates of the path of the first laser beam; projecting a second laser beam towards the point; moving the second laser beam in a predetermined pattern until the second laser beam reflects off of the reflective target generating a second feedback signal indicative of the second laser beam hitting the reflective target; calculating second vector coordinates of the path of the second laser beam; triangulating the first vector coordinates with the second vector coordinates establishing a digitized 3D coordinate of the point relative to the coordinate system; re

Abstract: A method and apparatus for generating a template for use in assembling a structure such as a truss. One or more laser scanners mounted above a work surface are controlled by a computer to generate a scanning laser image of all or a portion of the structure. The computer receives data describing the relative location of the individual work pieces in their assembled positions and the position of the laser scanner relative to the work surface. The computer generates a set of template defining data which is converted to a control signal and transmitted to the laser scanner.
