摘　　要：传统的征迁范围判定方法依赖于地面调查和分析,耗时耗力且难以实现高精度和高效率。因此,本文构建了一种基于数字航空摄影测量技术的征迁范围三维实景模型。首先,基于数字航空摄影测量技术,收集了征迁区域的高分辨率航空图像。其次,运用先进的三维重建算法,从处理后的二维图像中提取地形、建筑物等要素的空间信息,构建出征迁区域的三维实景模型。最后,通过实例数据验证了该方法的有效性。结果表明,通过所提的方法构建的三维实景模型在真实性和精确性方面均达到了很高的水平,能够有效地协助政府部门和项目管理者明确征迁范围。The traditional method of determining the scope of land acquisition relies on ground investigation and analysis,which is time-consuming,labor-intensive,and difficult to achieve high accuracy and efficiency.Therefore,this article constructs a three-dimensional real-life model of the relocation range based on digital aerial photogrammetry technology.Firstly,based on digital aerial photogrammetry technology,high-resolution aerial images of the relocation area were collected.Next,advanced 3D reconstruction algorithms are used to extract spatial information of terrain,buildings,and other elements from the processed 2D images,and to construct a 3D realistic model of the relocation area.Finally,the effectiveness of this method was verified through instance data.The results show that the 3D real scene model constructed by the proposed method has reached a high level of authenticity and accuracy,which can effectively assist government departments and project managers in clarifying the scope of land acquisition.
