차량용 시트 판재의 측정을 위한 알고리즘 개발

Lately a car seat is vitally considered functional face as well as comfortableness. Accordingly shape of the seat is more complex and needs much time on design. Reverse engineering is that the technology can resolve this problem by generating CAD models from the physical mockups or prototype models. The coordinate measuring machine(CMM) if often used to acquire the surface information of the part, but is limited in its measuring direction, which is fixed only along the z-axis. Also, large product is difficult due to work space's limitation of CMM. Detected features of various shapes to supplement these problems in this paper. Mostly measured objects include referenced shapes like circles or quadrangles for the registration process. The detecting method of the feature can be comprehensively applied considering the accuracy of the registration regardless of the shape. This method can perform registration using the feature without additional tools.
