20.500.12556/DKUM-45705 USPEŠNOST UPORABE ANALIZE SLIKE ZA OCENO CVETNEGA NASTAVKA, ŠTEVILA PLODIČEV IN PLODOV PRI JABLANAH SORTE 'DALINBEL' The success of the image analysis application for the forecast of flower basing, the number of fruitlets and ripe fruits in the 'Dalinbel' apple variety V letu 2013 smo na poskusni postaji Sadjarskega centra Maribor v Gačniku preizkušali natančnost napovedi pridelka z metodo avtomatskega štetja cvetov, plodičev in plodov v primerjavi z ročnim štetjem pri jablanah sorte ´Dalinbel´. Namen poskusa je bil preveriti natančnost digitalne prognoze cvetov, plodičev in plodov ter možnost za nadomestitev dosedanje metode ročnega štetja z novo, hitrejšo metodo analize slike. Metodo smo preizkušali v petih razvojnih fazah od začetka cvetenja do obiranja plodov ter povezanost rezultatov podali s Pearsonovim koeficientom linearne korelacije. V poskusu smo ugotovili, da je Pearsonov koeficient v fazi rdečega balona znašal r = 0.38, v fazi polnega cvetenja r = 0.67, v fazi pred redčenjem plodičev r = 0.30, v fazi po redčenju plodičev r = 0.55 in v fazi obiranja plodov r = 0.72. Ugotovili smo, da je metoda analize slike ponudila dokaj uporabne ocene v fazi polnega cvetenja in fazi zrelih plodov, v ostalih razvojnih fazah jabolk pa metoda analize slike ni ponudila uporabnih ocen. Na podlagi rezultatov izvedenega poizkusa smo ocenili, da lahko ob dodatnem izboljševanju metode in programa za štetje cvetov plodičev in plodov le-ta postane alternativa dosedanjim metodam ročnega štetja. In 2013 we have tested the accuracy of the apple harvest forecast with 'Dalinbel' variety carried out with the method of automatic counting of flowers, fruitlets and ripe fruits and the possibility of replacing the current manual method with the faster method of image analysis. The method was tested in five development phases from the blossom to the harvest of fruits. The results were presented with Pearson quotient of linear correlation. During the experiment it was established that the Pearson quotient in the phase of red balloon was r=0,38, in the phase of full blossom r=0,67, in the phase before fruit thinning r=0,30, in the phase after fruit thinning r=0,55 and in the phase of fruit harvest r=0,72. It was established that the method of image analysis offers very useful forecast in the phase of full blossom and in the phase of ripe fruits; however in other development stages of apple this method did not bring useful evaluations and results. On the basis of results of the experiment we assume that with further improvements in the programme for counting flowers, fruitlets and ripe fruits, the method of image analysis can become an alternative to the present manual counting. analiza slike ' Dalinbel ' napovedovanje pridelka umetni vid image analysis 'Dalinbel' harvest forecast image vision true true false Slovenski jezik Angleški jezik Diplomsko delo 2014-09-01 22:38:31 2014-09-26 15:02:15 2022-05-16 03:06:12 2021-05-03 03:30:56 2014 0 Maribor 0 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 URN:SI:UM:DK:NBDHCL2Y VS_Kokol_Jernej_2014.pdf VS_Kokol_Jernej_2014.pdf 1 6CB92DAA673717652460DD41A9FA1D88 f7f32bc5cc01d2ea189dab29b41bb616ba60b23bebdf395187c3caeddbf546a7 24a71419-7c0b-11eb-bb7a-00155d0001ca https://dk.um.si/Dokument.php?lang=slv&id=66365 Fakulteta za kmetijstvo in biosistemske vede 0 0 0
