Sea surface abnormal floating object detecting method based on remote sensing image

Abstract

The invention discloses a sea surface abnormal floating object detecting method based on a remote sensing image. An image denoising module performs denoising for a remote sensing image read in b a remote sensing satellite image. An abnormal object detecting module performs abnormal object detection for the image. A given information eliminating module is used for eliminating a given object on the sea surface. An abnormal object identifying module is used for classifying abnormal objects. An abnormal information collecting module is used for establishing weight graphs according to coordinate azimuth information and classification information attached to sub-images of the abnormal objects. An outputting module is used for merging the weight image graphs and the original remote sensing image and outputting results. According to the invention, the position where an air plane may crush can be quickly searched according to the remote sensing satellite image when there is no azimuth information of the air plane during the crash, thereby effectively reducing searching scope, and providing valuable reference information for searching.

Description

technical field [0001] The invention relates to the technical field of computer vision monitoring and the field of maritime search and rescue, in particular to a detection method for abnormal floating objects on the sea surface (possibly aircraft wreckage or survivors). Background technique [0002] For an aircraft that disintegrates in the air, the traditional search and rescue method is to calculate the possible landing location of the aircraft based on the reported position when the aircraft crashed, and then conduct search and rescue based on this possible location, mainly including sea surface ship search and rescue and aircraft search and rescue. Both methods rely on observation by the human eye. This method is very feasible for the traditional search and rescue environment where there is complete information on the position information provided when the plane crashes. For the search and rescue mission of position information, the traditional method is difficult to be...

AI Technical Summary

Problems solved by technology

[0004] The technical problem to be solved by this invention is to overcome the limitation that the traditional search and rescue method must rely on the orientation information provided when the plane crashes, especially the search and rescue difficulties encountered when the accurate orientation information cannot be provided when the plane crashes.
