无人机倾斜摄影技术在矿山大比例尺地形图测绘中的应用研究

传统矿山大比例尺地形图测绘效率低、周期长、作业成本高,针对这一问题,该文在深入分析倾斜摄影测量技术后,提出使用倾斜摄影技术进行大比例尺地形图测绘的作业方案。首先介绍无人机倾斜摄影技术,其次说明该技术在矿山地形图测绘中的作业流程,最后以实际项目为例,对作业中的关键技术进行介绍,并采用外业实地采集的检查点,对该文方案生产的地形图精度进行检测。结果表明,采用该文方案生产的地形图,其精度可以满足1∶500地形图测绘要求,而且较传统地形图测绘来说,效率高、作业成本低、周期短,具有一定的实用和借鉴意义。

The traditional mine large-scale topographic map has the advantages of low efficiency,long period and high operating cost.In order to solve this problem,after an in-depth analysis of tilt photogrammetry technology,this paper puts forward an operation scheme of large-scale topographic map surveying and mapping by using oblique photography technology.Firstly,the oblique photography technology of UAV is introduced,and then the operation flow of this technology in mine topographic map surveying and mapping is explained.Finally,taking the actual project as an example,the key technologies in the operation are introduced,and the check points collected in the field are used to test the accuracy of the topographic map produced in this paper.The results show that the accuracy of the topographic map produced by this scheme can meet the surveying and mapping requirements of 1∶500 topographic map,and compared with the traditional topographic map,the topographic map has high efficiency,low operating cost and short period,so it has certain practical and reference significance.
