微光彩色近红外 Low-light color near infrared SCMOS SCMOS

摘要

为了在微光条件下获取像白天一样兼具色彩和细节的图像, 提出一种微光下的彩色成像处理方法: 对彩色探测器图像进行降噪、增强和模糊处理, 提取其中的色彩信息, 对同时能接收可见光和近红外波段的高灵敏度黑白探测器图像进行降噪处理, 获得微光场景的细节信息, 在YCbCr色彩空间将色彩信息与微光场景的细节信息进行融合, 生成微光场景下的彩色图像。根据这种方法, 选择两款像元分辨率及像元尺寸相同的彩色和黑白SCMOS探测器, 设计并搭建成像处理系统。实验结果表明, 在0.01Lx的条件下, 处理得到的彩色图像符合真实场景, 适宜人眼观察。

Abstract

In order to obtain images with color and detail like daylight in low-light conditions, a color imaging processing method under low-light is proposed: denoising, enhancing, blurring the color detector images, and extracting color information; denoising the high-sensitivity monochrome detector image, which can receive both visible and near-infrared bands, and obtaining the details of the low-light scene. The color information is blended with the detail of the low-light scene in the YCbCr color space to generate a color image in the low-light scene. According to this method, two color and monochrome SCMOS detectors with the same pixel resolution and pixel size are selected to design and build an imaging processing system. The experimental results show that the processed color image conforms to the real scene and is suitable for human eye observation under the condition of 0.01Lx.
