摘　　要：目前矿山行业所使用的图像采集终端为手机、照相机、摄像机等小型图像记录设备,在暗光低照环境下采集的图像存在清晰度低、亮度低、图像失真和大量噪点等问题。为满足在矿山等低照度环境下采集到彩色清晰的图像的需求,通过开发低照图像去噪和低照图像增强算法软件、研究摄像头驱动、设计小型化大通光量摄像头模组,论文创新性的提出了应用于矿用手持终端的暗光成像技术,以及在相同的低照环境下与传统手持记录设备实验对比,得出本文所设计的暗光成像技术能有效抑制图像失真、图像噪点大问题,图像清晰度和亮度显著提高。At present,the image acquisition terminals used in the mining industry are mobile phones and cameras.,there are some problems such as low definition,low brightness,image distortion and a lot of noise in the images collected in the dark light environment.In order to meet the requirement that handheld recording equipment can still collect clear color images in low illumination environment such as mine,the algorithm software of low illumination image denoising and low illumination image enhancement is developed,the camera driver is studied,and the miniaturized large light quantity camera module is designed.This paper innovatively proposes a dark light imaging technology for micro-miniature terminals and in the same low illuminance environment with the traditional handheld recording equipment experimental comparison.It is concluded that the dark light imaging technology designed in this paper can effectively suppress image distortion and large image noise,and the image clarity and brightness are significantly improved.
