摘　　要：实景三维模型能够直观、准确、清晰地展示测区的地物信息,从而为城乡规划、环境保护等各行各业工作开展提供依据。获取精确数据是保证实景三维建模精度的关键,无人机的飞行高度、拍摄方式、相机性能等,都是影响影像精度的重要因素。实践表明,选择倾斜摄影、适当降低航高、科学布设控制点等措施能显著提高影像精度,让实景三维模型的可用性得到提升。3d real scene model can intuitively,accurately and clearly display the ground object information in the survey area,so as to provide a basis for urban and rural planning,environmental protection and other work in all walks of life.The acquisition of accurate data is the key to ensure the accuracy of 3d real scene modeling.The flight height,shooting mode and camera performance of UAV are all important factors affecting image accuracy.Practice shows that the selection of oblique photography,appropriate lowering of navigation height,scientific layout of control points and other measures can significantly improve the image accuracy,so as to enhance the availability of real 3d model.
