【摘要】：跳線聯(lián)板是輸電網(wǎng)中重要設(shè)備,其是否存在故障對(duì)輸電網(wǎng)正常運(yùn)行具有很大的影響。但由于現(xiàn)有的算法是對(duì)輸電網(wǎng)中所有的故障用統(tǒng)一的方法進(jìn)行識(shí)別,沒有對(duì)各類故障輸電設(shè)備進(jìn)行專門的研究,導(dǎo)致故障跳線聯(lián)板識(shí)別率低。為了高效識(shí)別紅外視頻圖像中故障跳線聯(lián)板,首先針對(duì)輸電線的紅外圖像特征,采用改進(jìn)的OTSU閾值分割圖像對(duì)紅外圖像進(jìn)行分割;其次,采用漫水法濾波分離各個(gè)連通域,運(yùn)用形態(tài)學(xué)濾去小區(qū)域,填充大區(qū)域內(nèi)的孔洞;最后,提取連通域的骨架,并從骨架圖像中提取出USFPF特征,通過該特征識(shí)別的故障跳線聯(lián)板。實(shí)驗(yàn)結(jié)果表明,識(shí)別故障跳線聯(lián)板準(zhǔn)確率為85.71%,漏檢率為14.28%,誤識(shí)別率為2.8%。該方法能夠較好地識(shí)別故障跳線聯(lián)板,具有較好的魯棒性。
[Abstract]:Jumper connection board is an important equipment in transmission network. Whether its fault exists or not has a great influence on the normal operation of transmission network. However, because the existing algorithm is to identify all the faults in transmission network by the unified method, there is no special research on all kinds of fault transmission equipment, which leads to the low recognition rate of the fault jumper board. In order to efficiently identify the fault jumper coupling in infrared video image, firstly, the improved OTSU threshold is used to segment the infrared image according to the infrared image feature of transmission line; secondly, the diffuse water filter is used to separate each connected region. The small area is filtered out by morphology and the holes in the large area are filled. Finally, the skeleton of the connected domain is extracted, and the USFPF feature is extracted from the skeleton image, and the fault jumper coupling is identified by the feature. The experimental results show that the accuracy of fault jumper coupling is 85.71, the missing detection rate is 14.28 and the error recognition rate is 2.8. This method can identify the fault jumper coupling well and has good robustness.
