无人机遥感是新近发展起来的一种先进的遥感方式，具有快速响应、机动灵活、影像分辨率高等特点。采用无人机对研究区森林进行航拍，探讨利用无人机影像提取 DEM 的技术方法，并对提取的 DEM 进行精度检验，然后在提取的 DEM 上叠加获得的高分辨无人机影像，独立实现了对研究区森林景观的三维可视化，结果表明利用无人机影像提取的 DEM 精度较高，生成的三维森林景观真实感强，能很好的展现森林的生态、文化、美学价值。

@@@@UAV remote sensing is a newly developed state-of-the-art remote sensing with fast response, flexible and high image resolution.We used images from UAV aerial to explore the technical methods of extracting DEM in the study forest area. After extracting DEM, the precision was tested.Then, we used the high-resolution UAV images to overlay on the extracted DEM, and separately accomplish the visualization of three-dimensional forest landscape.The precision of extracted DEM is high, and the three-dimensional forest landscape is with high sense reality.Therefore, UAV remote sensing is a good way to display the ecological, cultural and aesthetic values of forest.
