The Research And Implementation Of The Unmanned Aerial Vehicle Image Processing

UAV Also known as unmanned aerial vehicles, Mainly refers to an unmanned fixed-wing aircraft and unmanned helicopters. The system use of unmanned aerial vehicle platforms as a low altitude remote sensing and photogrammetry known as UAV low altitude remote sensing system(UAVRS). UAV remote sensing system is an high-tech of science and technology integrated unmanned aerial vehicles, remote sensing, GPS positioning and IMU attitude determination means, Etc,and it is a dedicated remote sensing system of the goal to obtain low-altitude high-resolution remote sensing image. It has low-cost,flexible, convenient,small-scale and economic characteristics. Therefore it widely used in dynamic monitoring of land use, mineral resources exploration, geological environment and disaster investigation, marine resources and environmental monitoring, map updating, forestry, pasture monitoring and agriculture, water conservancy, electric power, transportation, military and other fields of public security. In this paper, Target the characteristics of remote sensing for larger image rotation, image overlap irregular , photo angle larger, Etc. We do further research of unmanned aerial vehicle for remote sensing image processing using digital photogrammetry methods, Main content as follows:(1) analyzed the use of an ordinary digital camera to obtain UAV remote sensing image distortion model. used the iterative solution to correct original remote sensing image distortion correcting poor, to obtain corrected remote-sensing image(2) Studied the access method of the UAV remote sensing image that based on POS system(3) Studied the UAV remote sensing image matching methods, Target the characteristics of remote sensing unmanned aerial vehicle for large image angle, image rotation, and image overlap irregular , propose the Strategy of two-way matching that based on feature points extraction method based on harris operator.(4) Studied the unmanned aerial vehicle that based on POS system remote sensing image processing method of triangulation, Introduced WuCAPS the auxiliary Bundle Block Adjustment Software, And use the software Solve image of the region of the exterior orientation elements and coordinates of points(5) Designed a UAV pilot remote-sensing image processing system for unmanned aerial vehicle pilot remote-sensing image processing analysis...
