| titleOfInvention | Seabed tunnel remote sensing detection positioning method under background thermal radiation constraint |
| abstract | The invention discloses a seabed tunnel remote sensing detection positioning method under background thermal radiation constraint, belonging to the crossing field of ocean science, thermophysics, remote sensing and mode identification, comprising the following steps: obtaining an interested area according to the geographical position information of the original image, and filtering an image background in the interested area based on background thermal radiation constraint to obtain an image to be detected; dividing the image to be detected into a plurality of strip-shaped areas, calculating the gray level mean value of all the strip-shaped areas, wherein the strip-shaped area with the maximum gray level mean value is the submarine tunnel in the image to be detected. According to the invention, the filtering of a relatively low-frequency background is realized through the background thermal radiation constraint condition, and the frequency band where the target is located is highlighted, so that the detection and the positioning of the position of the submarine tunnel are realized. |
