摘要
由于传统无人机测量地形存在着像控点布设的繁琐、作业效率较低的问题,为有效解决其存在的缺点,现提出基于GNSS RTK+IMU无人机的免像控倾斜摄影地形测量方法.首先,基于GNSS RTK+IMU无人机获取摄影地形数据,实现地形的准确测量;其次,实现无人机免像控倾斜的数据影像匹配,得出各控制点的尺度、位置和方向等信息;最后,设定无人机摄影地形图绘制要求.实验结果:基于GNSS RTK+IMU无人机的免像控倾斜摄影地形测量方法能够有效实现地形的测量,其误差值最大为0.05m,证明该方法具有广泛的应用前景,特别是在地形复杂、人员难以到达的区域,能够提供快速、高效的地形数据获取能力.
Abstract
Since the traditional UAV terrain measurement has the problems of cumbersome image control point laying and low operational efficiency,in order to effectively solve its shortcomings,the image-control-free inclined photographic terrain measurement method based on GNSS RTK+IMU UAV is now proposed.Firstly,based on GNSS RTK+IMU UAV acquires the photographic terrain data and realizes the accurate measurement of the terrain,secondly,realizes the image matching of UAV image-control-free tilted data and derives the information of scale,position and direction of each control point,and lastly,sets the requirements for UAV photographic terrain mapping.Experimental results:the image-control tilt-free photographic terrain measurement method based on GNSS RTK+IMU UAV is able to effectively realize the measurement of terrain with an error value of 0.05m at most,which proves that the method has a wide range of application prospects,especially in the areas with complex terrain and difficult to reach by personnel,and is able to provide a fast and efficient ability to acquire terrain data.
