The invention provides a real-time three-dimensional modeling method, comprising the following steps: S101: collecting target image data; S201: establishing a 3D working cluster, and setting a mappingpath from a shared host computer and other computers to the host computer; S301: loading the collected image data into the work cluster, and encrypting the image data loaded into the work cluster; S401: According to the exterior orientation elements of the aerial triangulation image, the high-density data point cloud being obtained, the Tin model being constructed according to the high-density data cloud, and then the texture of the Tin model being automatically mapped. The invention can improve the speed of modeling and avoid the failure of air triangulation, which is convenient for model modification and data application. 本发明提出了种实景三维建模方法，包括如下步骤：S101：采集目标影像数据；S201：建立3D工作集群，并设置共享主机以及其他电脑到该主机的映射路径；S301：将采集的影像数据载入工作集群，对载入工作集群的影像数据进行加密处理；S401：根据空中三角测量运算出的影像外方位元素，获得高密度数据点云，并根据高密度数据云构建Tin模型，然后对Tin模型进行纹理自动映射。本发明能够提高建模的
