Abstract：Itisdificulttoeffectivelyextractthecompleteobjectregionincomplexscenesbytheexistingfeatureextraction methods，soamethodofcolor enhancementandconnectedregion construction basedonHSVspacenonlinear isproposed.On thebasisoftheobjectcolorfeatures，thehistogramdistributioncharacteristicsareanalyzedtoobtainthemultilevelthresholdsfor objectextraction.Forthecaseofporobjectextractionduetodiferentlightingconditions，theenancedextractionisperfored byconstructingthenonlinear mappingrelationshipbetweenhueandluminanceunderdiferentlightingconditions.Fortheregion of poorconnectivityintheextractedimage，thenearest-neighborskeletonconnection methodisproposedtoenhance the connectivityoftheobjectregion，soastomakeitconstituteacompleteobjectcontour.Bythedetectioncomparisonexperiments ofmulti-sceneobject extraction，theoverallaveragedetectionaccuracyrateof theproposed methodisimprovedbyO.1026in comparisonwiththatof themorphological processingmethd.Therefore，theobjectextractionmethodproposedcanimprovethe object detection accuracy rate of theunmanned detection platformsin complex scenes.
