DEVICE FOR ENHANCING SPATIAL RESOLUTION OF MULTISPECTRAL AEROSPACE IMAGE DATA BASED ON CLASSIFICATION OF SPECTRAL SIGNALS OF OBJECTS WITH AUTOMATIC CALIBRATION AT SPECIAL OBJECTS

摘要

The invention relates to devices for preprocessing multispectral aerospace images obtained by systems of earth remote sensing. A device for enhancing spatial resolution of multispectral aerospace image data based on classification of spectral signals of objects with automatic calibration at special objects comprises first, second and third ports with buffers, program memory, random access memory, bus interface, central processor with arithmetic and logic unit and mathematical coprocessor, timer, clock generator, memory interface, interrupt controller, event processor, unit for arrangement of instructions with instruction queue buffer, analyzer connected to data bus and random access memory. The analyzer comprises read-only memory with set of scene objects spectra, random access memory and adder and replenishes the flow of digital images with set of scene objects spectra during processing at central processor. The device further comprises calibration unit connected to data bus and random access memory. The calibration unit comprised read only memory with set of special scene objects spectra, random access memory and detector, and replenishes the flow of digital images with set of scene objects spectra during processing at central processor.
