Abstract:Short-wave infrared technology is a display technology that converts the characteristics of reflected short-wave spectrum of an object into an image. It has been rapidly developed in recent years, but there are few studies on low-illumination imaging for short-wave infrared. Aiming at the characteristics of short-wave night vision, we designed a multi-scale retinex model algorithm to enhance the night-time display effect of short-wave infrared, and designed a short-wave low-illumination 3DNR (three-dimensional noise reduction) algorithm, which significantly improved the image under low illumination. The signal-to-noise ratio lays the foundation for the development of imaging under short-wave infrared low illumination.
