Research On Open-pit Mine Monitoring Based On Low-altitude UAV Remote Sensing

There are many types of mineral resources and large reserves in my country,and some mineral reserves are at the forefront in the world.Mineral resources are relatively scattered,which is not conducive to people's supervision and management of natural resources.Therefore,it is necessary to use the mine dynamic monitoring system to curb illegal mining and standardize mining behavior.At present,the mine dynamic monitoring methods in my country are mainly the traditional step-by-step dynamic patrol statistical reporting data,the masses reporting social supervision and the use of high-resolution satellite remote sensing image assisting technology.Although there are remote sensing satellites providing image data,there are also actual situations in which the resolution is low and it is difficult to obtain accurate mining areas.It is difficult to monitor and manage high-precision and high-frequency areas in key areas.UAV remote sensing technology is widely used for its advantages of high resolution,fast data processing,strong autonomy,and fast response.This subject combines the UAV supervision and law enforcement project of large and medium-sized open-pit mines in Chongqing,based on previous theories and research,and uses the technology of rapid acquisition and processing of UAV data to discuss how to effectively use the low-altitude UAV remote sensing data processing system.Ideas and methods for carrying out mine remote sensing survey and monitoring work.By summarizing the composition and characteristics of the UAV remote sensing system,combing the low-altitude UAV remote sensing data acquisition process and how to quickly process the data,analyzing the technical advantages of the UAV remote sensing system,and further verifying the low-altitude Feasibility of the application of man-machine remote sensing technology in mine remote sensing survey and monitoring system.Through drone remote sensing technology,the aerial photography target of the mining area can be achieved.In these processes,mainly through clear missions,airspace approval,route determination,flight parameter settings,to obtain corresponding aerial image maps.Using Context Capture software and Pix4 d Mapper software to process data in the same test area,the work flow of using software to produce DOM,DSM and other products is summarized,and the differences between the two software,various features and differences of the software are compared and analyzed.Using artificial visual interpretation of remote sensing images,interpreting remote sensing images,combining with relevant data of mines to analyze the illegal mining situation of the mining area in the monitoring area,and quantifying the extent of illegal mining.According to the green mine construction standards,the construction of open-pit mines can be identified and the green construction can be mastered to promote the construction of "digital mines",which is of great significance for the sustainable development of mineral resources development and utilization.Compared with traditional monitoring methods,low-altitude UAV remote sensing monitoring is a more efficient and accurate technical method,which has obvious advantages in application.
