| 摘 要： | 以地面相机影像、低空无人机影像和地面三维激光点云数据为融合对象,研究空地影像融合、低空影像融合地面三维激光点云和低空影像融合三维白模进行三维建模的方法,并对其三维建模精度和建模效果进行综合分析。这3种融合方法进行三维建模丰富了三维模型的色彩纹理信息,提高了三维模型的几何结构精度,能满足较大场景的三维实景模型的建模要求,为数字化古建筑(古文物)保护提供具有较高价值的参考数据。

| Abstract: | Taking ground camera image,low-altitude UAV image and ground three-dimensional laser point cloud data as fusion objects,the methods of three-dimensional modeling of space-ground image fusion,low-altitude image fusion,ground three-dimensional laser point cloud and low-altitude image fusion three-dimensional white model are studied,and the accuracy and effect of three-dimensional modeling are analyzed comprehensively.These three fusion methods enrich the color and texture information of the three-dimensional model,improve the geometric structure accuracy of the three-dimensional model,and meet the modeling requirements of the three-dimensional real-world model of larger scenes,providing valuable reference data for the protection of digital ancient buildings(ancient cultural relics). |
