Abstract

In order to get the 3 dimensional data of an object, this research applied a shadow Moiré method to build an optical measurement system without touching the object to measure the contour for getting a 3D data. A digital camera was used to capture the Moiré images through an image processing to get the texture of each contour line. After calculated the texture of each contour line, the correspondence values are then filled. Each correspondence value will make smooth contour interpolation and then three-dimensional image of the object was plotted. This method for 3D measurement is simple and does not need an expensive measurement device to get precisely image information for a 3D rebuilt implementation.
