Technical field [0001] The present invention belongs to the field of photovoltaic technology imaging, particularly to an image reconstruction suitable for scanning transmissive micro optical imaging system. Background technique [0002] With the era of progress and development of technology, the photoelectric warfare equipment and equipment had leaps and bounds, while the photoelectric warfare equipment and the equipment must have picture identification, tracking and processing capabilities. A conventional optical imaging system is limited by design and manufacturing techniques, such optoelectronic devices and equipment against the target in the identification, tracking and processing capability is limited, it is difficult to further follow the pace of development of photovoltaic technology. [0003] Image reconstruction technique has been widely used, can further improve the identification, tracking and processing capacity objectives. Conventional image reconstruction, post imag...

Problems solved by technology

[0004] Existing image reconstruction technology uses multiple frames of low-resolution image sequences before and after time to generate a high-resolution image. The problem with this method is that there is a time lag and spatial gap between the multiple frames of low-resolution sequences before and after time. Displacement, there is an error in the input source of image reconstruction, which also leads to the bottleneck of the research on existing image reconstruction technology, and it is difficult to further improve the performance

In addition, in the photoelectric countermeasure system, the target in the image is a high-speed moving target rather than a stationary target, and there is lag and tracking error in the tracking of the photoelectric countermeasure system. In this case, using multiple frames of images before and after the image reconstruction, the error Large, the restoration effect is not good, and it is difficult to obtain the theoretical algorithm effect
