Superpixel micro-scanning method and corresponding infrared super-resolution real-time imaging device

Abstract

The invention provides a superpixel micro-scanning method and a corresponding infrared super-resolution real-time imaging device. The superpixel micro-scanning method includes that a paralleled plate rotates so that an image conducts a superpixel displacement D on an imaging plane of an infrared focal plane detector, and the displacement D is greater than a pixel space of the infrared focal plane detector. The corresponding infrared super-resolution real-time imaging device images an image on the corresponding infrared super-resolution real-time imaging device by an imaging lens, a variable speed rotating scanning structure is arranged between the imaging lens and the infrared focal plane detector, paralleled plates are arranged in the variable speed rotating scanning structure, the infrared focal plane detector is connected with an image processing and display circuit, the parallel plates always keep an included angle less than or close to 90 degrees with an optical axis. Under the premise that quality of a super-resolution reconstructed image is not affected, the rigor requirement for machining accuracy of micro-scanning on a scanning optical element can be reduced. For the conditions of detectors of different field frequency or different scanning modes, the effect of dynamic scene super-resolution real-time imaging is achieved.

Description

technical field [0001] The invention belongs to the technical field of infrared thermal imaging, and in particular relates to a super-pixel micro-scanning method and an infrared super-resolution real-time imaging device for low dynamic scenes based on the super-pixel micro-scan. Background technique [0002] Infrared imaging technology is a technology that converts invisible infrared radiation energy into visible images. It uses a detector sensitive to the infrared band to collect the infrared radiation energy distribution of the object, and then restores the image of the object through a suitable algorithm. Because this technology is passive, concealed, and adaptable to all-weather characteristics, it has extensive and important applications in military, medical, public security and other fields. [0003] However, due to the limitations of the current semiconductor manufacturing process, compared with ordinary detectors, infrared detectors have fewer pixels, larger pixel s...
