Application Of Low Altitude UAV Remote Sensing In Oilfield Engineering Measurements

In recent years, social demands for high-resolution images increase urgently with theeconomic development. Low Altitude Unmanned Aerial Vehicle Remote Sensing (UAVRS)as an emerging technology is a strong complement to aerial photogrammetry survey andsatellite remote sensing. Because of its flexible operation, low cost, simple take-off andlanding, high safety performance characteristics, it has been widely used in geologicaldisasters, land use monitoring and large-scale topographic map updates, etc. It is the maindevelopment trend of future aviation remote sensing.The purpose of this research is to find a viable method to promote the Low-altitudeUAVRS application in the oilfield, producing Digital Line Graph (DLG) and DigitalOrthophoto Map (DOM) by UAV images, and providing the basis construction material foroilfield.This thesis is based on the Xinjiang Shaya area in the original aerial material basis ofUAVS data processing. Firstly, this thesis introduces the low-altitude UAV remote sensingapplication status, the system components,and the impact of aerial factors, and sums upthe advantages and disadvantages of the UAV remote sensing image analysis, bycomparing with other remote sensing platforms. Secondly, according to the method ofmaking of Software Digital Line Graphic, Digital Elevation Model and Digital OrthophotoMap and UAV data collection presents two solutions, making Xinjiang Shaya region1:2000DLG; extraction and editing of the DEM data, the use of artificial visual editingand point cloud filtering are two ways to deal with to improve the accuracy of DEM data.Finally, through the digital differential rectification, the original image and DEM data aresuperimposed to generate the DOM. By the Mask Dodging method, histogram matchinguniform color method makes Digital Orthophoto Map tone equal, and using the knowncheckpoint estimates the accuracy of the DOM.The experiment proves that the low-altitude UAV remote sensing to quickly obtain atopographic map of the oil pipeline near the midline, the generated orthophotos fully meetthe layout and choice of oil exploration on the shot and well. The use of low-altitude UAV remote sensing tools for oilfield construction data is feasible, but there are certainrequirements for the accuracy of the original aerial image data.
