Abstract：Visibilityisreduced infoggyscenarios，andtheobjectinformationcapturedbyvehiclesinfoggyweatherisvague andincomplete，soitispronetofalsedetectionandmissddetection.Inviewof this，animprovedYOLOv8basedfoggyobject detectionalgorithmBRES-YOLOisproposed.FirstlyBiFormerisintroducedtoreplacethebackbonefeatureextractionetwork tocapturediferentsemanticfeatures，sostoenhancetheetectionaccuracyofthemodel.SecondlyanEMA（eficientmultiscaleattention）moduleisaddedtotheneck network toenhance the model'satentiontotheobject.TheSPD-Conv（space-todepthconvolution）isintroducedtoreplace theConvintheoriginalmodel toimprovethedetectionperformancewhendealing withimages withlowresolutionandsmallobjects.TheMPDIoU（minimumpointdistancebasedIoU）isusedtoreplace the originallossfunctiontoimprovethelocalizationauracyandclasificationperformanceofthedtectionframe.FinalytheCfRepGhoststructureisintroducedtoreplacetheoriginalC2f moduletolightenthemodelandreduce thecomputational complexityofthemodel.Theexperimentalresultsshowthatthe meanaverage precisionmAP@0.5of BRES-YOLO modelon RTTSdatasetis increasedby5.8%，anditsmAP@0.5：0.95isincreased by5.4%incomparisonwiththoseof YOLOv8n.In summary，the BRES-YOLO model can accomplish the task of object detection in foggy scenes more accurately.
