The invention provides a crimping fitting live-line detection method and device, and the method comprises the steps: obtaining a power transmission line inspection image, and extracting the appearancecontour features of a crimping fitting in an image feature extraction mode when the crimping fitting is detected from the power transmission line inspection image; dividing the crimping fitting intoa plurality of structural sections according to the appearance contour characteristics; and calculating the structural proportion of each structural section in the crimping fitting according to the pixel size occupied by each structural section, and obtaining the process detection result of the crimping fitting based on the comparison result of the preset proportion reference range and the structural proportion. The unmanned aerial vehicle is used for shooting the image of the crimping hardware fitting assembled on the power transmission line, the proportional relation between the crimping hardware fitting pressing area and the non-pressing area is judged based on the image feature recognition method, the crimping process is identified, and the technical problems that an existing crimpinghardware fitting detection mode consumes long time and the safety guarantee of inspectors is low are solved.
Description
technical field [0001] The present application relates to the technical field of electric power inspection, and in particular to a live detection method of crimping fittings. Background technique [0002] At present, crimping fittings are the main means to realize long-distance uninterrupted power transmission of UHV transmission lines. Commonly used crimping fittings include strain clamps and splicing tubes. With the rapid development of power grids, the voltage level is getting higher and higher, and power transmission Lines are becoming more and more dense, and the use of crimping fittings on transmission lines has also increased significantly, making the performance defects of crimping fittings an important factor affecting the safe and stable operation of the power grid. [0003] Since crimping is a hidden project, there are few methods to identify the quality of crimping during acceptance and operation, and the operability is not great. The existing detection methods m...
