This on line system measured seventeen critical dimensions on airbag diffusers. The system utilized both digital and analog camera technology to determine the accurate measurements of both Two and Three Dimensional contours. The system relied on multiple lighting strategies and image acquisition techniques.
On-line system for 3-dimensional profile measurements of railroad rails to an accuracy of 0.010" at a line speed of one hundred and eighty (180) feet per minute. Eight (8) laser line generators produce a structured light profile line around the rail. Ten (10) cameras acquire images of the laser line profile. The profile images are calculated and translated into 3-dimensional coordinates. The dimensional coordinates are reconstructed in computer memory to produce the a complete 3-dimensional profile of the rail. This system could be used to measure the counter of any outward facing surfaces. In the renderings below, the system is inspecting an octagon shaped tube.
On-line system for measuring the width and camber of steel plates to an accuracy of 0.010" at a line speed of one hundred and eighty (180) feet per minute. The system incorporates four cameras and four light line generators to acquire the images. The images are calculated and translated into 3-dimensional coordinates. The dimensional coordinates are reconstructed in computer memory to produce the a complete 3-dimensional profile of the steel plate.
This on line system was developed to measure wave distortions in the surface of ceiling tile. It allows engineers to determine the effectiveness of modifications to the drying process by measuring the amplitude of the waves to 0.005". Under certain circumstances the drying process can create waves in the ceiling tile surface that were large enough to warrant a sanding process. The sanding process waists a great deal of product. With this system the engineers are able to identify the culprits of the waves and eliminate the sanding process. This system has been installed in Europe and the United States.
On-line system for measuring the cast thickness of red hot steel strands. Two (2) laser line generators produce a structured light profile line on the steel slabs. Two (2) overhead cameras to acquire the images of the steel slabs. The system uses advanced triangulation techniques to calculate and translate the dimensional data for the thickness measurement.
On-line system for inspection of firebrick for surface defects, missing corners, divots and overall product consistency features. The system also measures the firebrick in (3) three dimensions to a tolerance of 0.015". The system inspects and measures one (1) firebrick per second and incorporates structured light line technology and 3D modeling techniques to acquire and display the three dimensional information.
Off-line system for 3 dimensional measurement of aluminum truck wheels to determine if sufficient wall thickness is available for machining. The first camera is aimed along the tangent of the wheel to acquire a profile of the outside edge. Two cameras track structured laser lines projected on the inside surfaces of the wheel. The wheel is rotated 360 degrees to produce a wall thickness model. The system uses advanced triangulation techniques to calculate and translate the dimensional data for the wall thickness measurement.
