Abstract It is necessary to remove the interferential stripes distributed on the TM6 night images, when we use them for thermal infrared investigation. A new method, "destripes filter" is introduced in this paper. The Key points of the method are to determine the position of these stripes by means of "median value" and to conduct a 2-dimensional smooth filter to delete the noise points which formed the stripes on the original images. It was proven in a thermal infrared detection and investigation of underground coal fire that the method could keep the original information better and make new satisfying images.
