Embodiment 1

[0078] In the embodiment of the present invention, the full chromatographic segment imaging is selected, and the aircraft carrier is selected as the simulation image for the image, such as image 3 In (a), it also contains sparse ocean background information. In the embodiment, t=4, each channel of information is decomposed into 8 bit planes, and there are 32 quantum state vectors of images in total. Such as figure 1 As shown in , by obtaining the above four channels of imaging information, the quantum filtering method combined with the system prior information point spread function PSF is performed, and then high-density quantum information is synthesized, and finally the filtered high-information image is reconstructed. figure 2 It is the decomposition diagram of different quantum planes, the larger the number of layers, the finer the information decomposition. Signal and noise can be finely decomposed in quantum space by layer-by-layer decomposition.

Abstract

The invention relates to a spaceflight optical remote sensing high-density quantization information processing method, and belongs to the technology of spaceflight remote sensing. The ground resolution of a conventional spatial optical remote sensor is difficult to improve at an on-orbit imaging stage because of the limit of the size of a detector, and a large amount of noise is generated on a focal plane because of the degeneration of the detector, thereby causing spot noise in an obtained image. An ideal effect is difficult to achieve through a conventional digital image processing method. Starting from the quantum state of information, the method gives consideration to the superposition state information, achieves the de-noising through the filtering in a quantum space, synthesizes a plurality of pieces of quantum information, and finally improves the information amount obtained by a system. The method is suitable for a satellite degeneration image or an image which is difficult to process on the ground, and hopefully, the method can be applied to the satellite-borne processing after the calculation complexity is reduced.
