The influence of low light level ICCD image on low light level and infrared image fusion

Abstract

The fusion of low light level and infrared images can synthesize the advantages of low light level imaging and infrared imaging, to make the details of the scene and targets richer. The quality of low light level and infrared images are the prerequisites to ensure the quality of fused image. The quality of low light level image is vulnerable to target contrast, light distribution and environmental illumination, especially under low illumination, low light level image noise significantly increased, image quality degradation, but the infrared image is not influenced by environmental illumination. In this paper, the influence of low light level image quality on low light level and infrared image fusion was analyzed from several aspects, such as target contrast, light distribution and ambient illumination, which can analysis the quality of low light level and infrared fused image.
