Problems solved by technology

However, the oil spill target recognition method based on hyperspectral technology proposed in the above literature only uses the ground measured spectral data as the criterion for target recognition, and does not consider the influence of spatial scale changes on the oil spill spectral absorption characteristics, so it is difficult to carry out the target recognition method with the ground continuous spectral data. Corresponding, not suitable for oil spill target identification

Abstract

The invention discloses a method and system for identifying an oil spilling target of a ship. The method comprises the following steps of: establishing a conventional oil type actual measurement spectrum database of the ship by use of actual measurement spectrum data of a conventional oil type through an ASD (Analytical Spectral Device) ground spectrometer; synchronously acquiring actual measurement spectrum data and imaging spectrum image data of different oil types by utilizing the ASD ground spectrometer and a vehicle-mounted high-spectrum sensor, acquiring rebuilt spectrum data by utilizing an experimental linear method, and carrying out precision evaluation on the rebuilt spectrum data by utilizing a similar coefficient method and optimizing a rebuilt scheme; and optimizing spectrum characteristics of an oil film according the actual measurement spectrum data and the rebuilt spectrum data, and selecting a spectrum section to carry out spectrum angle map identification. According to the invention, a problem that continuous spectrum data on the same ground can not match because absorption characteristics of multi-waveband images and satellite-mounted high-spectrum images are attenuated due to space scale change is solved, the oil spilling identification precision is improved to more than 85%, and fast identification of the oil spilling target based on a high-spectrum image is realized.

Description

technical field [0001] The invention relates to the technical field of marine environment monitoring, in particular to a method and system for identifying a ship oil spill target based on hyperspectral remote sensing. Background technique [0002] At present, in the field of marine environmental monitoring technology, there are many researches on oil spill monitoring using synthetic aperture radar SAR and multispectral sensor monitoring technology, and some achievements have been made. Identification of oil targets. [0003] Hyperspectral remote sensing technology has carried out a large number of hyperspectral detection and target recognition work in terms of land target detection and recognition, and has made progress. However, hyperspectral oil spill monitoring is still at a relatively low level, and there is a lack of understanding of the spectral response mechanism of oil slicks. We know that the composition, molecular size and molecular structure of organic matter in...
