First, the DANet and YOLOv4 are fused to solve the difficulty in understanding the scene and the discrimination of pixels caused by the complex and diverse scenes of UAV\u2019 (unmanned aerial vehicle) aerial images (lighting, viewing angle, scale, occlusion, and so on) so as to improve the significance of the detection target. Gaussian function and KL (Kullback\u2013Leibler) divergence are used to improve the nonmaximum suppression in YOLOv4 so as to improve the recognition rate of occluded targets; the focal loss function and the balanced cross entropy function are used to improve the loss function of YOLOv4 in order to reduce the impact of not only the imbalance between the background and the detection target but also the imbalance among the samples, which is aimed at improving the accuracy of the detection. Then, a data set is made for the experiment by using the UAV inspection image provided by a power grid company in Eastern Inner Mongolia. Finally, the algorithm proposed in this paper is compared with other target detection algorithms. Experimental results show that the average detection accuracy of the proposed algorithm can reach 94.7%, and the detection time of each image is 0.05 seconds. The method has good accuracy, real-time, and robustness.<\/jats:p>","DOI":"10.1155\/2021\/6235452","type":"journal-article","created":{"date-parts":[[2021,12,17]],"date-time":"2021-12-17T21:20:07Z","timestamp":1639776007000},"page":"1-12","source":"Crossref","is-referenced-by-count":4,"title":["Multitarget Detection of Transmission Lines Based on DANet and YOLOv4"],"prefix":"10.1155","volume":"2021","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-1270-2088","authenticated-orcid":true,"given":"Zhen","family":"Yang","sequence":"first","affiliation":[{"name":"Faculty of Electrical and Control Engineering, Liaoning Technical University, Huludao 125105, China"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1194-9428","authenticated-orcid":true,"given":"Xuefei","family":"Xu","sequence":"additional","affiliation":[{"name":"Faculty of Electrical and Control Engineering, Liaoning Technical University, Huludao 125105, China"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4784-6591","authenticated-orcid":true,"given":"Keke","family":"Wang","sequence":"additional","affiliation":[{"name":"Nanjing Institute of Electronic Technology, Nanjing 201139, China"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6056-257X","authenticated-orcid":true,"given":"Xin","family":"Li","sequence":"additional","affiliation":[{"name":"Faculty of Electrical and Control Engineering, Liaoning Technical University, Huludao 125105, China"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6106-8098","authenticated-orcid":true,"given":"Chi","family":"Ma","sequence":"additional","affiliation":[{"name":"Faculty of Electrical and Control Engineering, Liaoning Technical University, Huludao 125105, China"}]}],"member":"311","reference":[{"issue":"1","key":"1","first-page":"273","article-title":"Common problems in the operation of the high voltage transmission line and its maintenance","volume":"37","author":"L.
