POLYHEDRAL FACE RECONSTRUCTION AND MODELING FROM A SINGLE IMAGE WITH STRUCTURED LIGHT

The determination of the 3-D geometric model of visible polyhedral fac es from a single view is addressed. It applies a grid coding technique to derive the normal vector of each visible polyhedral face and the d epth parameter of the race equation based on the given dimensions of t he grid on the code plate. It is shown that the method is corresponden celess. Furthermore, it also determines the 3-D face model for all vis ible polyhedral faces including the occlusion relations between faces. Two edge reconstruction methods are given and their goodness are comp ared. For the determination of the final object model, three different integration methods are given. Some experiments are reported to illus trate the method.
