基于三维数码摄影测量的矿山地质应急测绘实践探索

Practice Exploration of Mine Geological Emergency Surveying and Mapping Based on 3D Digital Photogrammetry

由于传统方法在对矿山地质应急测绘实践中具有较大的中误差,为此提出基于三维数码摄影测量的矿山地质应急测绘实践探索。利用标定法对数码相机内在参数进行标定,通过Ethernet或串口将数码相机与飞行器连接,实现三维数码摄影测量技术对矿山地质数据的采集;然后运用V8配套预处理软件对图像数据进行增强处理,将处理后的数据统一储存到数据库中;最后通过GBKV603.2软件对矿山地质三维泡面图进行绘制,以此完成基于三维数码摄影测量的矿山地质应急测绘实践探索。经实验证明,此次提出的方法中误差低于传统方法,符合矿山地质应急测绘方法规程精度标准。

Because the traditional method has a relatively large error in the practice of mine geological emergency surveying and mapping,this paper proposes a practice exploration of mine geological emergency surveying and mapping based on three-dimensional digital photogrammetry.Use the calibration method to calibrate the internal parameters of the digital camera,connect the digital camera to the aircraft through Ethernet or serial port,and realize the collection of mine geological data by three-dimensional digital photogrammetry technology;then use V8 supporting preprocessing software to enhance the image data and process it.The processed data are stored in the database in a unified manner;finally,the GBKV603.2 software is used to draw the 3D bubble map of the mine geology,so as to complete the practical exploration of mine geology emergency mapping based on 3D digital photogrammetry.It has been proved by experiments that the error of the proposed method is lower than the traditional method,which is in line with the accuracy standard of the mine geology emergency surveying method.
