The Research Based On The Three-dimensional Map's Building By The Non-standard Navigate Picture

The information processing which kernel by computer technique is one of the symbols about the revolution of science and technology aider the World Warâ…¡.The computer science's fast development gives some advanced instruments and means for GIS(Geographic Information Systems).It is necessary for the national strategy's development and science and technology's progress which about city informatization.There are so many kinds of info to construct the digital city,but the most fundamental of them is the spatial geography info.The geography information's acquired mostly dependent on photogrammetry's development and consummate.Photogrammetry has run to its third phase-digital photogrammetry.It makes a far-reaching effect on the wholly photogrammetric logos,technology and application. The developments of computer science not only replace the enormous manual count, but have likely to identify the same point.Thereby it pioneers a robotic zed way for photogrammetry.It is hard to bring large navigate plane to renew the currently part-region-map data in some place.Security system became more important after the "911" event and many countries pay high attention on it.The commander wanted to have a three-dimensional scene around the terror environment which can reflect its new change.Subminiature Unmanned fixed-wing Aerial Vehicles(SUAV) is low-cost and portable,and they have good performances in payload and stability to wind. Obviously SUAV have enormous potential in civil and military application.It is an availability supplement for the geography spatial info collected by remote sensing and high-altitude navigate plane which by its current capability and its cost.It is so fit for the sub region's images collected because of its low altitude of flight,small volume,light weight,agile flight and convenient landing or flying-off.And also because of those the data it collected cannot reach the aerial survey's standard.This research's target is to build three-dimensional map by the data which collected by the SUAV.The author wanted to solve the problem in Photogrammetry by machine vision after lots of investigations and analyses about the theory of Photogrammetry and machine vision.We pretreated the nonstandard navigate picture collected by SUAV and adopted an improved algorithm to grey it.We did an improvement algorithm of characteristic point's extracting and matching Contra posed its specialty,and programmed the algorithm to prove its feasibility.In this paper the author brought out a new algorithm to estimate the F matrices-weighted random sampling algorithm.I programmed to complete the step of increasing the characteristic points based on this algorithm for the hypsography continuity.For the point's world co-ordinate's accuracy,we used a calibration algorithm which considered the lens first-order aberrant.And then we used the result to build the work area's Digital Elevatation Model(DEM).We made an improvement on the Delaunay triangulation net's Divide-and-Conquer algorithm based on the rule net spanning technology.And at last the work area's relief map can be browsed by this new system.In the process of this research the author considerd many different kinds of compile environmental relative merits.VC++6.0 should be used in the major system's programmer and matlab should be used in the calibration procedure and so on which need more calculation.The author also used OpenGL to compile the browse module and disposed the interface of matlab,VC++6.0 and OpenGL smoothly.The system software has been modularized and abstracted and has a good ability of portability and cross-platform.This software can be transmitted from Windows to Linux smoothly.The software has a good ability of interaction, openness and extension.This software has strong function,good security and is easy to operate and maintain.
