Method and device for remotely measuring oil pollution area of offshore sea area

The invention relates to a remote measuring method and device for an oil pollution area in an offshore sea area. The method comprises the following steps: acquiring a satellite remote sensing image sequence based on the offshore sea area; performing key information reconstruction on the satellite remote sensing image sequence to obtain a target image based on an offshore sea area; preprocessing the target image to obtain a denoised grayscale image, and recording the denoised grayscale image as a first image; performing edge detection operation on the first image to obtain a second image; performing oil spill area detection on the second image to obtain an oil spill area image, and calculating the area of an oil spill area in the oil spill area image to obtain a calculation result; eliminating the interference area in the calculation result to obtain the final area of the oil spilling area; and carrying out visual display on the final area of the oil spilling region. According to the method, key information re
