Spaceflight optical remote sensing high-density quantization information processing method

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.

At present, it is difficult to effectively improve the imaging quality of satellites in orbit, and it is necessary to further improve the image quality through digital image processing.

[0003] Due to the limited size of detector pixels, it is difficult to improve the imaging resolution of optical imaging satellites in orbit, and the amount of sampled information is low; in addition, due to changes in the space environment, many complex factors cause the performance of detection components to degrade, or due to the inherent characteristics of detection devices , degrades the image quality and affects the image interpretation. It is often difficult to obtain the desired effect by using traditional methods.
