气体泄漏红外成像探测具有高效率、远距离等显著优势。为了进一步增强观察人员对气体泄漏红外图像的细节感知, 等效提高系统探测极限, 提出一种基于双边滤波的气体泄漏红外图像动态压缩及增强方法, 以气体泄漏红外图像特点为依据, 对双边滤波和压缩合并过程进行控制, 实现了气体泄漏红外图像细节的有效增强。实验表明, 在实现从高位宽原始数据到低位宽输出显示数据压缩的同时, 气体泄漏痕迹信息得到显著增强, 且整幅图像具有较好的对比度, “光晕”现象得到有效抑制。

As the gas leak infrared imaging detection technology has significant advantages of high efficiency and remote imaging detection, in order to enhance the detail perception of observers and equivalently improve the detection limit, a novel gas leak infrared image compression and enhancement method based on bilateral filtering is proposed. The method controls the process of the bilateral filtering, compressing and enhancing according to the characteristics of the gas leak infrared image. The experimental results demonstrate that the trace of gas leak is enhanced significantly, the contrast of the entire image is appropriate, and the halo effect is suppressed effectively.
