Uma Proposta para a Reconstrução 3D Semi-automática de Sólidos Geométricos baseada em imagem 2D

To maintain the real time characteristics of a feedback system it is a premise that actuation is synchronous with acquisition signal. In digital systems, intermediate processing with various digital filters can interfere in this synchronism. This work presents a multirate digital filter design approach with constant group delay. Thus, synchronous condition in real time mode can be maintained. The presented method uses an iterative process to design the filters applied in simultaneous multirate data acquisition systems, such as in sensor network applications. When these applications requires joint data channels analysis to extract consistent information, if the time reference is modified, the system causality would be damaged generating incorrect results.
