The application discloses a kind of unmanned vehicle multispectral
remote sensing water fine classification extraction method, it is related to
remote sensing image processing technical field, the joint
feature matrix including spectral feature, gray
texture feature and elevation difference feature is creatively constructed in the present application, effectively eliminates redundant interference information, provides high-quality input with very distinguishing degree for multilayer
perception machine model.Simultaneously, illumination geometry and
digital elevation model are deeply coupled in the feature construction process, not only can accurately identify and reverse inhibit the shadow pseudo
water body feature projected by complex
terrain or building, break through the failure limitation of traditional single elevation filtering in flat shadow area, but also cooperate with the
standardization closed operation process based on morphological dilation and
corrosion filtering, eliminate the small holes and jagged artifacts in prediction result, realize the high-fidelity restoration of
water body boundary, so as to improve the classification accuracy of complex
water body such as narrow river, fragmented pit pond and urban waterlogging.
