Application Study Of ZY-3Satellite Images To Produce Basic Geographic Information Data

With Remarkable achievements were scored in such fields as Digital computingtechnology and Communication technology and space technologies to promote thedevelopment of modern satellite remote sensing technology,many kinds of remote sensingdata with different temporalresolution and spatial resolution and spectral resolution spring upat an increasing rate.Remote sensing data has become increasingly prominent role In thenational economy and national defense construction.zy-3remote sensing data representadvanced technology of the high and spatial resolution and the positioning accuracy asChina’s first civilian high resolution earth observation satellite.moderate resolution of ZY-3data has great potential used in basic geographic information data acquisition、homelandsecurity,environmental monitoring,disaster prevention-mitigation and long-term plan as a newtype of remote sensing data source.Although ZY-3data has established the relationshipbetween the image and ground targets with high geometry,but the capability of ZY-3datamake good use of basic geographic information data including1:50000,1:25000and1:10000scale acquisition still remain to be confirmed.How to take advantage of ZY-3data is theprimary objective after ZY-3access to remote sensing data successfully.The graduation thesis based on ZY-3data.We study on imaging principle,Precisepositioning of forwardlooking-backwardlooking stereo image,stereo model reconstitution,Theinformation extraction of three-dimensional,the image correction,registration,fusion,colorprocessing and mosaic cutting between of multispectral image and vertical-looking imagesand get basic geographic information products later.Then we will make the accuracy andexpression ability of ZY-3data based on basic surveying and mapping data and imageprocessing results for the expectation of ZY-3data used in different specifications and different sacle.finally,we will draw a conclusion of the universal adaptability of ZY-3data inuse of Large-scale production in basic geographic information data field.The research priorities of this graduation thesis is properties and principle of ZY-3images,Precise positioning of ZY-3stero and multispectral images and the technical andquality control process adapt to the wildly use of ZY-3in basic geographic information datafield.
