METHOD AND SYSTEM FOR GENERATING AN IMAGE-TEXTURED DIGITAL SURFACE MODEL (DSM) FOR A GEOGRAPHICAL AREA OF INTEREST
摘要
A computer-implemented method for generating an image-textured digital su rface model (DSM) for a geographical area of interest (21) including both bu ildings and terrain may include using a computer (24) to generate a digital elevation model (DEM) (40) of both the buildings and terrain for the geograp hical area of interest (32). The method may further include providing a coll ection of optical images including oblique optical images for the geographic al area of interest including both buildings and terrain (34). The computer may also be used to selectively superimpose oblique optical images from the collection of optical images onto the DEM of both the buildings and terrain for the geographical area of interest and to thereby generate the image-text ured DSM (46-49) for the geographical area of interest including both buildi ngs and terrain (36).
