摘　　要：高精度3维激光扫描技术的出现,为建立一套覆盖完整、细节清晰、视觉效果突出、数据真实准确的数字石窟提供了可能。云冈石窟3维数字化工作就是将3维激光扫描技术应用到石窟的制作,利用激光测距原理,以最精细、最合理的技术手段记录石窟的密集点的3维坐标、反射率和纹理等信息,完整保留全面、准确、细致的3维数据,进而复建出石窟的3维模型及线、面、体等各种数据,将云冈石窟清晰地展现出来。The high-precision 3D laser scanning technology offers the possibility to establish a set of digital grottoes that includes the complete coverage,clear details,prominent visual effects and true and accurate data.The 3D digital engineering of Yungang Grottoes is the application of 3D laser scanning technology to the production of process.It uses the laser ranging principle and it records the grotto of the 3D coordinates of the point,reflectance and texture information by the most sophisticated and reasonable technical means.It retains the complete,comprehensive,accurate,and detailed 3D data,and the resumption of the construction of the 3D model of the grotto and line,surface,volume and other data.It will clearly show the Yungang Grottoes.
