摘要
En 中文
Evaluation of profile error is important in manufacturing and detection of complex surface. In this paper, an algorithm is presented to calculate surface profile error accurately based on linear quadtree after rough localization and accurate registration. In rough localization, the best transformation is selected from four transformations. Then two algorithms are adopted to realize accurate registration and comparison is performed. One algorithm is the combination of LM algorithm and ICP algorithm. The other algorithm is BFGS algorithm. Experiment result shows that complex surface profile error is evaluated effectively through the proposed algorithm. (C) 2013 Elsevier Ltd. All rights reserved.
