20.500.12556/DKUM-93447 Uporaba konvolucijskih nevronskih mrež za detektiranje krošenj dreves Using convolutional neural networks for detecting tree canopies Diplomsko delo se ukvarja z razvojem računskega modela za detektiranje krošenj dreves v tlorisni sliki gozda. Na osnovi študija literature smo ugotovili, da je problem najlažje rešljiv z uporabo konvolucijskih nevronskih mrež. Za praktični del tega zaključnega dela smo izbrali prepoznavalnik YOLO (angl. You Only Look Once). Svojo rešitev z uporabo različice YOLO v7 smo implementirali v orodju DarkNet. Pripravili smo lastno zbirko slik, ki smo jih zajeli s pomočjo brezpilotnega letalnika. Množico podatkov smo ustrezno razdelili v učno in testno množico. Analiza dobljenih rezultatov je pokazala, da je naša rešitev zmožna prepoznavati krošnje dreves v tlorisnih slikah gozdov. Metrika natančnost je bila nad 90 %, je pa bila metrika priklic nekoliko nižja, tj. okrog 50 %. Diplomsko delo podaja tudi nekaj smernic za uporabo tako naučenih modelov v gozdarstvu. The thesis deals with the development of a computational model for the detection of tree canopy on the top-down image of a forest landscape. Based on a literature study, we found that the problem is most easily solved using convolutional neural networks. For the practical part of this thesis, we have chosen the YOLO (You only look once) recogniser. We have implemented our solution using YOLO v7 in the DarkNet toolbox. We have created our own collection of images captured by a drone. We split the dataset into training and test sets accordingly. The analysis of the obtained results showed that our solution is able to recognize tree canopy in top-down images of forests. The accuracy metric was above 90%, but the recall metric was slightly lower, i.e. around 50%. The thesis also gives some guidelines for the application of such learned models in forestry. strojno učenje konvolucijske nevronske mreže model “You Only Look Once“ (YOLO) računalniški vid prepoznava objektov s slike machine learning convolutional neural networks You Only Look Once (YOLO) computer vision object recognition from images true true false [J.
