Methods for automated real-time acquisition of marine mammals (acquisition)

摘要

To monitor the presence of marine mammals based on detecting thermal signature of (TSMM) is manually by wardens far , or has been performed in a simple partial prototype automated only . With such a method , there is a problem in image processing with a quick and reliable combined with ease of use of the altitude. The method according to the invention , in fragments in the image pre- processing step (FPP), image correction and complete image segmentation , which has not been weighted (SEG); in the detection process (DET), based on the detected local contrast change use of threshold algorithm ; in the classification process (CLA), for the subdivision of the two classes , use of the help monitored learning of support vector method with a hyper plane (HE) (SVM); localization of in step (LOC), the distance of the detected thermal distinguishing characteristics (SMM), and automatically calculate the changes that over time and space for the vessel (RV); in the verification process (VER), the moment of decision by the operator specific check of possibility ; and , in the documentation process (DOC), including automatically providing a user-specific image data of the detected thermal signatures of marine mammals (TSMM) (IRV). Infrared camera system with a complete or partial peripheral monitoring (IRC), and an active gyroscope stabilization against the horizon (HZ), are used to produce the data .
