Abstract：Inallusion to the problems of slow speedandlowaccuracyof orange petal appearance detection in canned citrusproduction，aswellasthehigherparametercountofmainstreamdetectionmodels，alightweightorangesegment appearancedetectionmodel，OO-，ispropsed.Inthemodel，animprovedEcientVietworkisitroducedbysing theHardSwish activation function as the backbone.The mapping similaritybetween diferentdetection heads isreduced by inputingfeaturesatdiferentlevels，whichaleviatesredundantcalculations，andenhancesthenetwork'sfeatureextraction capability bymeansofcascaded groupatention mechanism.Aslim-neck modulethat fuses thepropertiesof standard convolutionanddeepseparableconvolutionisreferenced toreducethesizeofthemodelwhilemaintaining highaccuracy.In orderto furtherreduce the model sizeandspeedupinference spee，SPPCSPC isreplaced with the SPPFstructure.Inorderto alignwiththepositionalcharacteristicsoforangesegmentsinthedataset，theMPDIoUlossfunctionisusedtoimprovethe regresionacuracyof the predicted bounding boxes.The experimentalresults showthatthe proposedorange segmentappearance detection model is63.81%smalerin size compared to YOLOv7，whilerealizing a detectionaccuracyof 96.57% .After deploymentandtestingontheJetsonOrinNano，thebalancebetweenmodelsizeanddetectionaccracyissignificantlymproved compared to similar methods，meeting the requirements of the canned citrus production line.
