摘要
针对海洋雾气环境下摄像机类设备图像对比度低、能见度差的问题,提出了一种基于图像前处理的单图融合增强去雾方法,首先对大气辉光分量进行校正,其次结合图像传感器R通道透射率高的特征利用小波融合技术提升图像细节,最后利用导向滤波器以进行图像去雾增强,通过实际浓雾环境下采集的图像对比处理实验验证了所提出方法的可行性、有效性.
Abstract
Aiming at the problems of the low image contrast and poor visibility issues of camera devices in marine fog environments,a single-image fusion-enhanced dehazing technique based on image preprocessing is proposed.Firstly,correction of the atmospheric glow component is conducted.Secondly,combining the characteristics of high transmission rate in the R channel of image sensors,a detail improved image is obtained using wavelet transform and blending.Finally,the guided-filter is used to enhance the image dehazing.The effectiveness and feasibility of the proposed dehazing method are validated through comparative analysis of algorithm processing effects on images collected in actual dense fog environments.
