| 摘 要： | 雾天条件下,利用侦察设备获取的目标区可见光图像对比度低,不能满足指挥员对战场目标的识别判断。文章基于大气散射理论建立了适于远距离雾天图像退化模型,根据雾天能见度、波长和景深等计算所需空间变化光学深度,并通过实例验证了该方法能有效复原低质量可见光侦察图像,具有很强的实用性。

| Abstract: | The visible images in the target area which are obtained by scout equipment under fog conditions can not satisfy the commanders for the battlefield target recognition because of the poor contrast of the images.Firstly,a degraded model for the long distance images in foggy days is established based on the atmospheric scattering theory.Secondly,the optical depth for the visibility change is calculated according to the visibility,wavelength,depth of field and so on.Finally,some degraded visible scout images are restored in order to validate the effectiveness and practicality of this method. |
