Abstract:The matching and localization precision of hull blocks directly affects geometrical error evaluation in hull block construction. The evaluation parameter plays an important role in the precision management of hull blocks. Meeting the multifeature model localization requirement through the traditional pose-matching method is difficult. The sequential matching and localization of the multifeature model were studied in accordance with the error distribution optimization theory of data-matching technology to identify the best pose matching of hull blocks and to provide a reasonable method for the evaluation for construction precision. In this study, the installation process was considered. Feature sections were positioned in accordance with differences in regional precision. The iterative solution method based on model transformation theory and that integrates regional tolerance constraints was applied. It is a practical technology used for precision size monitoring in shipbuilding. Theoretical and experimental results confirmed the validity and rationality of the method related to the traditional least-squares method and showed that the proposed method can provide a quantitative data basis for the verification of models and subsequent assembly. ? 2019, Editorial Department of Journal of HEU.
