基于BRDF可见光偏振成像技术的海面溢油油种识别研究
Oil spill-type identification based on BRDF visible polarization imaging technology on sea surface
摘要
Abstract
The oil spill type needs to be promptly identified after the occurrence of a marine oil spill to provide timely and effective response measures for its disposal.The BRDF multi-angle measurement device and visible polarization camera were used to observe clean seawater and different oil types.The best observation Stokes pa-rameters and corresponding observation geometries were selected based on the visible polarization characteristics.The datasets of clean seawater and different oil types were constructed,and the DBN oil spill-type identification model was established based on the BRDF visible polarization characteristics.Under controlled conditions in a laboratory,the combination of relative azimuth angles of-60°,0°,and-30° produces better oil identification re-sults,while the light source zenith angle and camera observation angle have better recognition effects when ap-proaching±50°.Multiple repetitions of experiments showed that the optimal recognition rates for seawater,crude oil,heavy oil,gasoline,diesel oil,and palm oil were 90%,86.27%,84%,80.44%,82.08%,and 82%,respectively.The experimental results show that the oil-type recognition model based on the visible polarization characteristics has a good effect on the oil spill-type identification on the sea surface.关键词
