Generation of surface shape from variable-resolution video moire contours
Several methods for generation of three dimensional surface shapes from variable resolution video moire contours are described. In a classical moire system, a physical grating is projected on a target and also used to view ...
Real-time generation of intersection of surfaces for welding by video moire
A common problem in fabrication and welding of complex structures is that there is no simple way to determine where to cut one part so that it will fit another part unless both parts designed and built on a CAD/CAM system. ...
Detection and location of pipe damage by artificial-neural-net-processed moire error maps
A novel automated inspection technique to recognize, locate, and quantify damage is developed. This technique is based on two already existing technologies: video moire metrology and artificial neural networks. Contour ...
Variable-resolution video moire error map system for inspection of continuously manufactured objects
Moire techniques can be a powerful tool to determine deviation of a manufactured shape from a desired shape. In a traditional moire system, distorted gratings on an object are viewed through an undistorted grating. The ...
