Application Of Unmanned Aerial Vehicle Technology In Orogenic Drawing

With the development of modern science and technology,the application of modern technology products has become a trend in many field work with dangerous or heavy workload.Such as UAV aerial technology,has been widely used in various fields,in the field of geological survey is no exception.The low-altitude unmanned aerial vehicle remote sensing has the advantages of small size,strong pertinence,rapid response capability and low running cost.It is becoming a useful complement to the aerospace and remote sensing system.Remote sensing geological interpretation is an important working method of regional basic geological survey.With the development of UAV remote sensing image stitching technology,the image splicing effect can meet the requirements of 1: 500,1: 1000,1: 2000 and other large scale precision.UAV remote sensing shooting almost free from the atmosphere clouds image,take off the time is short,can quickly take off to a certain height,shooting meet the requirements of the image,timeliness,shooting time flexible.At present,UAVs have been widely used in geological disasters,mine monitoring,geological surveying and other fields.(1)Taking the Bangong Lake-Nujiang metallogenic belt as the experimental area,according to the 2016 test situation,the feasibility of the application of the UAV in the orogenic belt is explored,and the preliminary solution is put forward.Technology,the use of new means to provide theoretical and empirical support.(2)In the 1: 50000 or 1: 10000 large scale mapping,in the construction of complex areas,compared to artificial large scale mapping is likely to cause geological missing,with a higher resolution than the satellite UAV In the conglomerate area,the band synthesis of the satellite usually reflects the characteristics of gravel or matrix components,prone to misjudgment;and unmanned aerial vehicles can clearly reflect the conglomerate of the conglomerates.Sedimentary structure.Because each photo carries GPS information,you can more accurately identify the boundary contact limits and contact relationships,magmatic rock range and other related information.(3)Due to the UAV and traditional remote sensing platform,the use of unmanned aerial vehicles,making large scale mapping,the individual focus on rock ore body,to achieve multi-dimensional,high precision possible.Relative to the traditional artificial mapping,UAV more economical,green.Through the UAV scanning,after the interpretation of geological personnel and then the geological body of the verification,virtually saving a lot of manpower and material resources.And this way of working,no doubt reduce the large number of vehicles,personnel in the outdoor workload,more in line with industry trends.
