| 摘 要： | 针对不同地形环境下存在的飞行安全性低、数据冗余、构建三维模型质量和精度差等问题，本文以单镜头四旋翼小型无人机为试验设备，对平坦地形环境下的复杂单体建筑使用井字形交叉航线和环视航线；对复杂山地地形环境下的泥石流沟谷使用水平航线、井字形交叉航线及视频航线构建三维模型，并结合航线参数、三维模型质量和精度，探讨了不同地形环境下无人机航线规划方案对三维模型构建的影响。经评价分析可知:①使用环视航线能安全、快速地获取平坦地形下的复杂单体建筑影像，构建完整、质量好、精度高的三维模型；②使用井字形交叉航线能构建山地地形下泥石流沟谷的完整、质量好、精度高的三维模型，但飞行安全性、时效性较低；③使用视频航线，影像重叠度高，能构建完整、质量好的三维模型，模型精度并无明显差异。

| Abstract: | Aiming at the problems of low flight safety, data redundancy, and poor quality and accuracy of constructing 3D models in different terrain environments. This paper uses single-lens quad-rotor small UAV as the experimental equipment. To the complex single building in flat terrain environments uses tic-tac-toe cross routes and circumferential routes. To the mudslide gully in complex mountain terrain environments uses horizontal routes, tic-tac-toe crossing routes, and video routes to construct the 3D model. Combined with route parameters, 3D model quality accuracy, the influence of the UAV route planning scheme on 3D model construction under different terrain environments is discussed. As indicated by the results, used the circumferential route could safely and quickly acquire images of complex single building in flat terrain, and construct a complete, good quality, and accurate 3D model.Used the tic-tac-toe cross routes can construct a complete, good quality, and accurate 3D model of the mudslide gully in mountainous terrain, but the flight safety and timeliness are low. Used the video routes, the image overlap is high, and a complete, high-quality 3D model can be constructed, the accuracy of the model is not significantly different. |
