運用專業手法對產品進行數據復原的過程稱為逆向（抄數），工程師通過專業儀器進行數據采集，用專業軟件進行模型構建、完成三維圖檔、為公司新品研發提供高精度數據。The process of using professional methods to restore product data is called reverse engineering(Chaoshu). Engineers use professional instruments to collect data, use professional software to build models, and finally complete 3D graphics files to provide high-precision data for the company's new product research and development.
