It is important to the development of precision agriculture using advanced remote sensing technology and target detection method to extract crop information rapidly and accurately.Based on this,a high-resolution UAV image was proposed as the data source to train YOLOv3 network with labeled data and to obtain the optimal parameter estimation and form a neural network for orange trees,so as to realize the recognition of the dense orange tree images.In order to prove the reliability of the experiment,the same sample was used for comparison based on the Deep Learning module of ENVI5.6 platform.The results show that the proposed method can efficiently extract orange tree information from UAV images,and its identification accuracy is better than that of Deep Learning module of ENVI5.6 platform.The model is stable and reliable which can be applied as a selective method for crop statistics.
