Based On Matrix System Of UAV Aerial Image Applied Research

Low-altitude UAV aerial photography system developed rapidly in recent years,it has became a new type of aerial photographic survey technology,and with the continuous Gmprovement of its function and the improvement of all aspects of the technology mature gradually,it also has widely applied in all fields.Low-altitude UAV aerial photography system not only operation cost is low,and flexible,accurate and fast,and it in a small area or flight comparison difficulties were the areas can be very fast to obtain high resolution images,all of these characteristics and advantages in the meanwhile improve the surveying and mapping results,improve the emergency services of surveying and mapping support capability,etc.,play the role of the infinite.Thesis mainly to complete the work:1.Using the Matrix in the software system of Zhejiang flight image processing and precision analysis,and combined with its application in practical engineering,emphatically summarized in using the Matrix when dealing with the low-level image technique,including the controversial point editor dleled when coarse almost need to be aware uf,the technique of image pioccssing by EPT,and so on.2.Analysis of previous photogrammetry software deal with the causes of failure of UAV image automatic relative orientation,study the Matrix steady eliminate the gross error and ensure the uniform distribution point method,and studied the automatic relative orientation strategy.3.Splicing method of Matrix is studied,its according to solve out the projection center of indirect global coordinates of all control points,and then based on the least squares solution of all the Homography Matrix of the initial value,then the L-M algorithm for global optimization of the Homography Matrix,all images to achieve global registration of stitching.4.Through the instance analysis MapMatrix and VirtuoZo absolute orientation module.Because of their different absolute orientation principle,VirtuoZo mapping when adjacent model can produce line is poor,and MapMatrix won't produce,thus its own unique advantages that compared with VirtuoZo.
