非制冷红外焦平面图像存在对比度低、分辨率低、细节信息不全、视觉效果差等缺陷，实际应用中需要增强红外图像以改善其质量。一种基于线性映射与直方图均衡化加权结合的高动态范围红外图像增强技术，通过线性映射对红外原始图像做图像增强，保存数据，再利用直方图均衡化算法对红外原始图像做图像增强，选取适当的权值，将增强后的图像加权结合，得到最终图像。重点分析了传统线性映射与直方图均衡化的原理与处理方法，通过多幅高动态范围场景的红外图像的处理比较，表明该算法操作简单，且处理后效果显著，可用于实时增强。

Uncooled infrared focal plane image has many disadvantages like low contrast, low resolution, incomplete detail information, poor visual effect, which needs to be enhanced to improve its quality in practical application. A high dynamic range infrared image enhanced technology is based on the weighted sum of linear mapping and histogram equalization. This paper focuses on the analysis of the principle and method of the traditional linear mapping and histogram equalization. And through comparing the high dynamic range infrared images in different scenes, it shows the simplicity and feasibility of this method.
