无人机航摄技术在大比例尺测图中的应用研究

以无人机航摄技术在大比例尺(1∶1 000、1∶500)地形图测绘中的应用为研究目的,采用固定翼无人机平台,搭载非量测型数码相机,于河北某矿区进行航摄大比例尺地形图制作实验,通过外业实测点位数据对测图高程及平面精度进行评估。实验结果表明:通过严控误差影响因素无人机航摄技术可以满足1∶1 000比例尺测图精度要求,1∶500比例尺测图精度无法满足。最后,基于精度评定数据对误差产生的原因进行了深入分析与探讨,为无人机航摄技术测绘大比例尺地形图应用的可行性及可靠性提供了经验。

ApplicationR esearch of UAV Aerial Photography Technology in Large Scale Mapping

The research purpose is the application of UAV aerial photography technology in large scale mapping (1∶1 000, 1∶500). A fixed wing UAV platform was used to carry out the test in Hebei Province which carried a non measurement digital camera .The ex-perimental results showed that the accuracy of 1∶1 000 scale mapping could be satisfied by the strict control of error factors.The accu-racy of 1∶500 scale could not be satisfied.Accuracy evaluation was implemented and the feasibility and reliability of the application were investigated, which will provide priori experiences for large scale topographic mapping using the UAV aerial photography technol-ogy.
