摘　　要：针对在复杂的扫描环境下,三维激光扫描点云数据容易缺失、噪点多,点云预处理难度大且效果不理想,进而影响后期模型重建精度和效率的问题,该文对融合三维激光扫描和多视图影像重建两种技术进行了研究,提出了一种全新的快速精细化模型重建方法。结合某工程实例,基于分块建模的思想,运用该方法完成了数字三维模型的重建工作。实验结果表明,该方法可以建立高精度的三维模型,并在很大程度上提高了建模的效率。Under the complex scanning environment, 3D laser scanning point cloud data are easy to loss and contain a lot of noise, and the pretreatment of point cloud is difficult and the effect is not ideal, thereby will affect the precision and efficiency of model reconstruction. To solve the problem, this paper studied the combining 3D laser scanning technology and multi view image reconstruction technology and put forward a new method to fast complete the fine model reconstruction. Taking one engineering project as an example, the reconstruction of digital 3D model was realized based on the idea of block modeling re- construction. Experimental results showed that the proposed method could establish high precision 3D model and greatly improve the efficiency of the model reconstruction.
