    摘 要 :電力巡檢在輸電線路部件故障的排除中起著至關(guān)重要的作用。為了實(shí)現(xiàn)復(fù)雜背景下的輸電線路電力小部件的目標(biāo)檢測(cè),提出了一種改進(jìn) SSD 算法的小目標(biāo)檢測(cè)算法——PA-SSD。將反卷積融合單元融合到 PANet 算法中,以改進(jìn) PANet 結(jié)構(gòu),并以此為基礎(chǔ)產(chǎn)生新的特征融合方式,融合不同尺度的特征圖 ;將傳統(tǒng) SSD 算法中的特征圖用新的特征圖替換,形成新的特征金字塔模型。針對(duì)實(shí)際輸電線路中的 4 種目標(biāo)進(jìn)行了測(cè)試,結(jié)果表明,PA-SSD 算法與原始的 SSD 算法相比,其檢測(cè)精度有了明顯提高,檢測(cè)速度也可以滿足檢測(cè)性能的要求。

    Abstract: It is of great importance for the power inspection to troubleshoot the transmission line components. In order to achieve target detection of small power components of transmission lines in complex contexts, this paper proposes a small target detection algorithm based on the improved SSD algorithm-PA-SSD. The deconvolution fusion unit is integrated into the PANet algorithm to improve the PANet structure, and on this basis, a new feature fusion method is generated to fuse feature images of different scales. The feature graph in the traditional SSD algorithm is replaced with a new feature graph to form a new feature pyramid model. The results show that compared with the original SSD algorithm, the detection accuracy of PA-SSD algorithm is significantly improved, and the detection speed can also meet the require ments of detection performance.
    Key words: target detection; transmission line; SSD algorithm; PANet algorithm
