Description

technical field [0001] The invention belongs to the technical field of photography and imaging, and in particular relates to a satellite remote sensing three-line array three-dimensional image processing system and method. Background technique [0002] In order to meet the different needs of different users for satellite remote sensing images, practitioners in the field have proposed a method for classifying geometric products of satellite remote sensing images. However, the current commonly used general imaging geometric model - strict imaging geometric model is aimed at single-chip satellite products, and there are few reports on the research on other levels of geometric products and their general imaging geometric models. Therefore, according to the characteristics of satellite remote sensing stereo images, it is necessary to study its general imaging geometric model to improve the application level of satellite remote sensing stereo images. [0003] As shown in Table 1,...
