摘要
为提高地质测绘图像的清晰度,引进无人机遥感技术,设计矿山地质精细化测绘方法。根据无人机遥感测绘作业的需求,参照采用航空网络和地区网络的布局方式,利用航线网络,在各高程航线间设置适当数量的像控点;使用CGO技术,处理测绘中的网络平差数据,采集无人机遥感测绘信息;计算镜头误差的方式,建立一元线性回归方程,补偿并处理测绘数据;自动连接多个提取点,执行自动操作,转化成果文件;利用地质空间复合体模板,录入点、线、面等参照性数据,生成矿山地质测绘结果三维模型,实现对矿山地质的精细化测绘。以某地区大型矿山工程为例,设计对比实验,实验结果证明:设计的地质测绘方法,在矿山地质测绘时的实用性更强,可以确保测绘图像的清晰度在80%以上。
In order to improve the clarity of geological mapping images,the UAV remote sensing technology is introduced and the mine geological fine mapping method is designed.According to the requirements of UAV Remote Sensing Surveying and mapping operation,with reference to the layout of aviation network and regional network,an appropriate number of image control points are set between the altitude routes by using the route network;Use CGO technology to process network adjustment data in surveying and mapping and collect remote sensing surveying and mapping information of UAV;The method of calculating the lens error,establishing a linear regression equation,compensating and processing the surveying and mapping data;Automatically connect multiple extraction points,perform automatic operations,and convert the result files;By using the geological space complex template,the reference data such as points,lines and planes are input,and the three-dimensional model of mine geological mapping results is generated to realize the fine mapping of mine geology.Taking a large-scale mine project in a certain area as an example,a comparative experiment is designed.The experimental results show that the designed geological mapping method is more practical in mine geological mapping and can ensure that the clarity of the mapping image is more than 80%.
