四旋翼无人机影像获取及DOM生产研究

Four Rotor UAV Image Acquisition and DOM Production

利用四旋翼无人机系统对试验区进行了低空航拍,快速获取了试验区内满足航测处理的影像数据,并对其航飞质量及影像质量进行了客观评价;同时利用四旋翼无人机系统自带的GPS、方向及高度传感器装置及试验区内的历史资料,进行了基于POS及历史资料2种方式的空中三角测量,研究了利用四旋翼无人飞控系统获取正射影像的可行性,并对其DOM成果精度进行了评价。

Using the low-altitude aerial photography by the four rotor UAV system, with quick access to meet the aerial image data processing in the region of interest, this paper evaluated the l ight quality and the precision of result objectively. At the same time, through the historical data of the region of interest, and the system-provided GPS and inertial navigation device, this paper studied the feasibility to obtain orthogonal projection image by the four rotor UAV system after aerial triangulation in two different ways of POS and the historical data. At last, the precisions of results had been evaluated.
