不同颜色照明下的水下成像差异研究孙杰,王红萍,张丹,余义德(中国人民解放军91550部队,辽宁大连,116023)摘要:针对低照度、浑浊水质环境中水下成像系统观测能力受限的问题,从辅助照明光源的角度,设计了水池实验方案,分析不同浑浊程度的水质条件下光源光谱特性对水介质散射特性的影响。实测数据分析表明,不同颜色的辅助光照明下,水体的散射系数存在差异,低浓度的水体对蓝光的散射系数较大,蓝光照明的成像效果并不理想,而随着浓度增加,红光的散射系数逐渐接近甚至大于蓝光。研究结果不仅有助于优化水下成像系统中照明光源的参数设置,而且能够为去散射方法的应用,以及获取高质量的水下观测视频提供强有力的技术理论支撑。关键词:水下成像;辅助光源;散射特性中图分类号:TJ630.34;U674文献标识码:A文章编号:2096-3920(2023)04-0648-06DOI:10.11993/j.issn.2096-3920.2023-0046DifferencebetweenUnderwaterImagingwithIlluminationSourceswithDifferentColorsSUNJie,WANGHongping,ZHANGDan,YUYide(91550thUnit,thePeople’sLiberationArmyofChina,Dalian116023,China)Abstract:Sincetheobservationabilityofunderwaterimagingsystemsislimitedintheenvironmentoflowilluminationandturbidwater,theexperimentalschemeofthepoolwasdesignedfromtheperspectiveofanauxiliaryilluminationsource.Theinfluenceofspectralcharacteristicsofilluminationsourceonscatteringcharacteristicsofwatermediumunderdifferentturbidityconditionswasanalyzed.Theanalysisofmeasureddatashowsthatthescatteringcoefficientsofwaterbodiesaredifferentundertheauxiliaryilluminationsourceswithdifferentcolors.Thescatteringcoefficientofbluelightislargerinwaterwithlowconcentration,andtheimagingwithbluelightisnotideal.Thescatteringcoefficientofredlightislargerthanthatofbluelightwithincreasingconcentration.Theresearchresultsnotonlyhelptooptimizetheparametersofilluminationsourcesinunderwaterimagingsystemsbutalsoprovidestrongtechnicalandtheoreticalsupportforapplyingde-scatteringmethodsandobtaininghigh-qualityunderwaterobservationvideos.Keywords:underwaterimaging;auxiliaryilluminationsource;scatteringcharacteristic0引言水下光学成像探测是获取水下目标物状态信息的重要手段,但是在海洋环境中,光波的传输特性并没有空气中那样优良...
