Abstract

In this work the Gray code method for numerical 3D reconstruction of complicated objects was implemented. Based on structured projection, the Gray code method projects in different binary patterns. Grouping this sequence, this sequence of patterns allow to describe 2ⁿ different directions of projection, where each direction corresponds to a word in binary code. Thus, each point in the observation field corresponds to a unique binary code that can be identified in the digitized image. The surface object introduces a lateral shift of each binary word in relation to the reference plane. A digital procedure that identifies each code, allows calculating the lateral shift and the corresponding height. The technique of gray code is easy to implement, it is flexible to the size of the object and it can resolve discontinuity objects. The system was designed to reconstruct human faces and was evaluated using objects of well-known form. Experimental results are presented and discussed.
