矿山测量中特殊地形的测绘技术方案分析

Analysis on the technical scheme of surveying and mapping special terrain in mine survey

由于传统的测绘技术,在进行矿山测量中特殊地形的测绘时没有将图像像素灰度值进行处理,因此相邻控制点之间的距离中误差大,无法实现矿山测量中特殊地形的精准测绘。针对这一问题,进行矿山测量中特殊地形的测绘技术方案分析。通过特殊地形数据坐标格网的标定公式,绘制特殊地形数据坐标格网;将图像像素灰度值进行处理,改变图像原有的灰度值,提高矿山测量中特殊地形图像数据的清晰度,进而将控制点按比例尺展出;利用专业软件进行拼图处理,获取特殊地形测绘数字正射影像图,完成测绘。设计方案分析,结果表明,设计的测绘技术在相同的控制点中对特殊地形测绘相邻点之间的距离中误差明显低于实验对照组,相邻点之间的距离中误差更小,能够实现矿山测量中特殊地形的精准测绘。

Due to the traditional surveying and mapping technology,the grayscale value of image pixels is not processed when mapping special terrain in mine surveys,so the error in the distance between adjacent control points is large,and the precision of special terrain in mine surveys cannot be achieved Surveying.Aiming at this problem,the technical analysis of the special terrain surveying and mapping in the mine survey is carried out.Through the calibration formula of the special terrain data coordinate grid,draw the special terrain data coordinate grid;process the image pixel gray value,change the original gray value of the image,improve the clarity of the special terrain image data in the mine survey,and then The control points are displayed on a scale;using professional software for puzzle processing to obtain digital orthophoto maps of special terrain surveying and mapping to complete the surveying and mapping.The analysis of the design scheme shows that the designed surveying and mapping technique has a significantly lower error in the distance between adjacent points of the special terrain surveying and mapping in the same control point than the experimental control group.The error in the distance between adjacent points is smaller and can Realize the precise mapping of special terrain in mine surveying.
