电力巡检吊舱的红外成像环境复杂,导致红外系统的成像效果不理想。针对此问题,从巡检目标的特殊温度特性入手,引入二维小波变换与直方图均衡相结合的方法,对图像进行滤波处理。以电力巡检吊舱采集的红外图像作为实验对象,对其进行图像增强处理。提高了图像的对比度,并很好地提取出了陡峭的边缘,突显了电力线路。实验结果验证了所提出的增强算法的可行性。

The infrared imaging environment of the power inspection pod is very complex, which results in the bad effect of the infrared imaging system. Aiming at this problem, a new method combining the two-dimensional wavelet transform with the histogram equalization based on the temperature characteristics of the special inspection target is proposed in this paper. According to the filtering process of the image, this method can improve the contrast of the infrared image and extract the steep edge. It also can highlight the power lines. The experiment implemented on the infrared image taken by the power inspection pod can verify the feasibility of the enhancement algorithm proposed by this article.
