Airborne hyperspectral infrared overflowing oil monitoring method and system

Abstract

The invention provides an airborne hyperspectral infrared overflowing oil monitoring method and a system, wherein the method comprises the following steps: before finding an overflowing oil area, entering a search mode, rapidly acquiring hyperspectral image of overflowing oil on sea surface through a fourier transformation infrared imaging spectrometer with adjustable space resolution and spectrum resolution; performing image splicing fusion to the acquired hyperspectral images through a motion compensation system, to obtain the hyperspectral images of large-range sea surface overflowing oil, and compensating the field-of-view change brought by airplane platform motion through the posture, motion status and position information of an airplane; judging whether the overflowing oil area exists according to the hyperspectral images of large-range sea surface overflowing oil, if yes, switching to an analysis mode; under the analysis mode, controlling the monitoring field of view of the fourier transformation infrared imaging spectrometer to be always aligned with the overflowing oil area through the motion compensation system, wherein the infrared imaging spectrometer acquires high-precision spectrum information within small range; and performing recognition on the types of overflowing oil according to the high-precision spectrum information.

Description

technical field [0001] The invention relates to the field of airborne hyperspectral infrared oil spill monitoring, in particular to an airborne hyperspectral infrared oil spill monitoring method and system. Background technique [0002] In recent years, with the increasing prosperity of international maritime trade, the ocean transportation industry has developed rapidly. However, the ensuing marine oil spill pollution has surpassed heavy metal pollution, chlorinated hydrocarbon pollution, radioactive pollution and thermal pollution in the ocean, and has become the most serious problem in marine pollution. Oil pollution caused by ships and tankers has become focus of attention of the international community. At present, the frequency of marine oil spills accounts for about 80% of all marine pollution. Marine oil pollution has become the most common, most widely distributed, and most harmful type of marine pollution. It is characterized by a wide range of diffusion. , high ...
