摘　　要：针对文物的保护问题,提出了一种以结构光测量技术来实现文物保护的数字化工程方法。首先,对文物的三维数据进行精简、去除噪声和光顺等预处理;接着,利用一种快速定位基准点的三点定位配准方法,实现数据的多视配准;最后,由三角网格方法将三维数据整合成三角曲面片网格,建立文物的数字化模型。该方法在快速建立青铜器文物的数字化模型中得到了充分验证,且能满足数字博物馆文物保护工程的应用要求。For digital preservation of cultural relics ,a 3D digital method for culture heritages was proposed using structured light scanner. Firstly,the preprocess of 3D points cloud was carried out,such as data simplify,noise data deleted and smoothing. Next step was using a method based reference point to register multiple points cloud by three point sets. Finally,a triangulated method was used to integrated 3D points cloud into the triangular patches and a digital model of cultural relics was quickly reconstructed. The examples of constructing 3D models of bronzes have been presented,and the prefect results have been obtained in the engineering of cultural preservation for digital museum.
