Abstract: Methods to generate three-dimensional images using moire techniques with segmentation and reconstruction are presented. Moire techniques have been employed in many areas, presenting alternatives to laser scanner for research and technical applications. However, one challenge for the widespread use of moire techniques is associated with the reliability in presenting object images that are free of noise effects at their edges; these are associated with shade areas generated by the illumination process. Three-dimensional views under multiple angles could overcome this limitation. Two methods for the observation and reconstruction of images to obtain the desired section of the reproduced object were adopted. They were tested on distinct object shapes; the image reconstructions exhibited the ability to reproduce regular as well as irregular body geometries. (c) 2008 IAgrE. Published by Elsevier Ltd.
