Annotation method based on monolithic InSAR (interferometric synthetic aperture radar) orthophoto

Abstract

The invention discloses an annotation method based on a monolithic InSAR orthophoto. The method comprises the following steps: 1, acquiring the monolithic InSAR orthophoto; 2, annotating based on the monolithic InSAR orthophoto according to the following annotation processes: 201, establishing a ground object characteristic database of the InSAR orthophoto, 202, carrying out indoor interpretation: determining and positioning ground objects according to the ground object characteristic database of the InSAR orthophoto, 203, carrying out outdoor check, 204, carrying out annotation and supplement measure on a shadow region and a layover region, 205, carrying out annotation and supplement measure on new added ground objects and concealed ground objects, and 206, carrying out indoor data processing; and 3, carrying out junction processing. The annotation method which has the advantages of reasonable design, simple step, convenient realization, good usage effect, and high annotation precision allows practical problems that present fully digital aerophotogrammetry systems and annotation methods cannot satisfy annotation needs of the InSAR orthophoto, the annotation effect of the monolithic InSAR orthophoto is bad, technical advantages of an InSAR cannot fully performed and the like to be solved.

Description

technical field [0001] The invention belongs to the technical field of airborne synthetic aperture radar interferometry, and in particular relates to a mapping method based on a single InSAR orthophoto image. Background technique [0002] InSAR (Interferometric Synthetic Aperture Radar; abbreviation: Interferometric Synthetic Aperture Radar or Synthetic Aperture Radar Interferometry) technology originated in the United States, and has been continuously improved and matured in developed countries in Europe and the United States, and its application fields have also been continuously promoted. For countries with developed InSAR technology, such as the United States and German space information industry technology companies, the practical airborne high-resolution InSAR technology has been used as a new and advanced technical means for terrain surveying, forest surveying, Resource investigation and environmental mapping, geological environment and disaster monitoring, etc., and ...
