摘　　要：再制造毛坯的结构形貌具有复杂性和不确定性,对其测量和评价要实现定量化、精确化、可视化是本文的目标。提出了一种新方法,即基于逆向工程技术实现再制造毛坯的数字化建模和可视化分析。以应用实例详细说明了该方法涉及的关键技术,包括再制造毛坯数字化测量技术、测量点云的预处理技术、数字化模型配准比较技术以及再制造模型的可视化评价等。The purposes of this paper are to realize quantitative, accurate and visible measurement and estimation, because the shape and configuration of remanufacturing roughcasts are usually complicated and ambiguous. Then a new method is put forward based on the digital modeling and visible analysis technique of remanufacturing-roughcast in reverse engineering. Furthermore, the key techniques involved are emphatically demonstrated, which mainly including the digital measurement of remanufacturing-roughcasts, point cloud pre-processing, three dimensional models registration and compare, remanufacturing model visible analysis and so on.
