基于逆向工程的明代圈椅模型重构与设计创新

目的 通过数字化模型的重构降低圈椅三维建模的难度，缩短以明代圈椅为原型进行设计创新的周期。方法 基于逆向工程技术、三维激光扫描仪和Imageware反求软件，获取圈椅的三维数字化点云数据，借助Pro/Engineer软件进行结构优化设计，形成圈椅的数字化原型。对圈椅的椅圈、靠背等零部件进行创新设计，通过组合重构的方式形成全新的圈椅形态。结论 借助逆向工程对传统家具进行设计创新不仅有益于明代圈椅的传承，并在减低设计创新成本，缩短设计周期方面也具有重要的意义。

Model Reconstruction and Innovation Design of Ancient Round-backed Armchair Based on Reverse Engineering

The work aims to reduce the difficulty in constructing 3D chair through the reconstruction of digital model, and shorten the design innovation cycle of the Ming Dynasty chair. Based on the reverse engineering technology, the 3D laser scanner and the Imageware software, the arm-chair''s 3D digital data was obtained, and the structure was optimized with Pro/Engineer, and the digital prototype of arm-chair was completed. The innovation design focused on the modelling change of circle and backrest, and the new form of chair was combined by reconstructing the parts. This research is not only beneficial to the inheritance of Chinese classical furniture, but also has important significance in reducing the cost of design innovation and shortening the design cycle.
