Embodiment Construction

[0014] The present invention is described in further detail below in conjunction with accompanying drawing:

[0015] The portable airborne marine oil spill remote sensing monitoring system of the present invention adopts PCA&BP (principal component analysis combined with BP network) method modeling, carries out the identification of marine oil spill, and its identification algorithm is as follows:

[0016] 1. PCA modeling for oil spill identification

[0017] 1.1, PCA algorithm

[0018] The main process of principal component analysis is divided into feature selection process and feature extraction process. In the feature selection process, the input space is mainly mapped to the output space to obtain the input features, that is, the input principal components; and the feature extraction process is also a dimensionality reduction process, in which the main features are selected and other features are discarded. portion.

[0019] (1) Feature selection process: The purpose o...

Abstract

The invention provides a portable airborne marine oil spill remote sensing monitoring system, and relates to the marine pollution monitoring field. The system comprises an infrared/ultraviolet/multispectral digital camera, a central control and display system as well as a data management and image processing operation software system. The central control and display system records image information acquired by the infrared/ultraviolet/multispectral digital camera, and superposes the information with an electronic chart for on-line or off-line track playback; and the data management and image processing operation software system which is arranged in a portable industrial control computer of the central control and display system reads the image information, identifies oil spill on line, computes contaminated area on line and identifies thick oil film. The system has the advantages that the portable airborne marine oil spill remote sensing monitoring system can be expediently equipped on various ocean patrol planes without power supply from the planes; when a marine oil spill accident happens, the system can track the marine oil spill in real time, estimate oil spillage and the contaminated area, and evaluate the oil spill elimination effect.

Description

technical field [0001] The invention relates to the technical field of marine pollution monitoring, in particular to a portable airborne remote sensing monitoring system for marine oil spills. Background technique [0002] International airborne marine oil spill remote sensing monitoring system products include AIREYE (infrared / visible light) from the United States, MSS from Sweden, and the most famous one is MSS5000 from Swedish Aerospace Corporation. At present, many developed countries such as Spain, Sweden, Greece, Holland, Finland, and the United States are equipped with MSS5000. [0003] Foreign patents on airborne marine oil spill remote sensing monitoring include: Airborne Infrared / Ultraviolet Oil Spill Remote Sensing Detector (USA), Patent No.: 5461236; Method and Instrument for Monitoring and Measuring Oil Spill (USA), Patent No.: 7009550. A large number of literature shows that foreign airborne oil spill remote sensing monitoring technology is composed of two par...
