According to the <a href="https://www.bp.com.cn/content/dam/bp/country-sites/zh_cn/china/home/reports/bp-energy-outlook/2020/energy-outlook-2020-edition-cn.pdf.pdf" target="_blank"> 2020 Energy Outlook</a> released by
<a href="https://www.bp.com/" target="_blank"> <b>BP</b></a>, global electricity
demand will increase by about 80% by 2050, and the total mileage of grid
expansion required globally in the next decade will be 16 million kilometers.
In China, with the development of UHV technology and the major national
strategic plan for power transmission from west to east, the mileage of
transmission lines has developed more rapidly. As of 2020, the length of
transmission lines of 220kV and above in China is 794,000 kilometers
(<a href="http://prpq.nea.gov.cn/uploads/file1/20211009/616135ef5d67c.pdf" target="_blank">2020 National Electricity Reliability Annual Report</a>), and the mileage
of lines under construction will reach 41,000 kilometers
(<a href="https://neec.no/%e5%b9%b4%e5%ba%a6%e9%87%8d%e7%a3%85-%e4%b8%ad%e5%9b%bd%e8%83%bd%e6%ba%90%e5%a4%a7%e6%95%b0%e6%8d%ae%e6%8a%a5%e5%91%8a%ef%bc%882021%ef%bc%89-%e7%94%b5%e5%8a%9b%e7%af%87/?lang=zh-hans" target="_blank">China Energy Big Data Report 2021</a>). Therefore, regular inspection of
transmission lines is necessary for the long-term safe operation of
the power grid.
</p>
<p>
Power inspection includes power component inspection and transmission
line defect inspection. In recent years, with the development of computer
vision, two-stage represented by R-CNN series and single-stage represented
by <a href="https://www.cv-foundation.org/openaccess/content_cvpr_2016/html/Redmon_You_Only_Look_CVPR_2016_paper.html" target="_blank"
><b>YOLO</b></a> and <a href="https://openaccess.thecvf.com/content_ICCV_2019/html/Duan_CenterNet_Keypoint_Triplets_for_Object_Detection_ICCV_2019_paper.html" target="_blank"
><b>CenterNet</b></a> have achieved good detection results on various general
datasets such as <a href="https://paperswithcode.com/dataset/pascal-voc" target="_blank"
><b>VOC</b></a> and <a href="https://cocodataset.org/" target="_blank"
><b>COCO</b></a>. The fast iterative update of the general
object detection algorithm makes it possible to perform accurate real-time
detection of power components in power transmission scenarios.
</p>
<p>
To meet the needs of power component detection algorithms,
we release the largest publicly available power component dataset - <a href="#data-dataset"
><b>WHU</b></a>.
The WHU dataset consists of two kinds of high spatial resolution UAV images,
with a total of 1347 scene images, covering the common types of electrical
components of general power ele components, with rich annotations and complex
image backgrounds, which can be used for various Algorithm evaluation provides
a data basis, and at the same time, it can meet the actual needs of production
and provide necessary data for various engineering practices.

<p>
WHU is composed of the two spatial resolution of drone
images shot alternately from the perspective of the distance,
covering the types of power components commonly common in the
current transmission line, which can basically meet the
needs of scientific research and engineering practice.
Specifically, WHU consists of 1347 high -resolution drone images,
covering Insulator, Pylon, Spacer, Vibration Damper, Nameplate, Grading Ring, Nest
and external intrusions in the overhead transmission lines, and there are 12050 detection boxes
marked. According to the ratio of 7:2:1, WHU is divided into three groups: training, verification and testing.

Specific workflow: After the operator on the ground enters the inspection path channel,
