The invention provides a power equipment X-ray image registration method, which comprises the following steps of: firstly, enlarging the data volume through data enhancement modes such as rotation, translation, noise and contrast, so that the robustness to noise and illumination variation can be improved, and the diversity of data can also be improved; then, through a lightweight spatial conversion network, carrying out conversion on a floating image with a relatively large attitude, angle, voltage and focal length change to achieve coarse registration, so that conversion efficiency and precision are improved; and finally, accurately registering the fixed image and the floating image through a preset feature conversion algorithm, so that the registration effect is improved. According to the image registration method provided by the invention, registration of X-ray detection technical parameters and image quality identification and defect detection requirements of power equipment can be achieved, and the problems of low registration efficiency, insufficient data utilization and poor effect of a traditional registration method when physical parameters such as a shooting angle and voltage change greatly are solved; and high-quality X-ray images can be effectively obtained.
Description
technical field [0001] The present application relates to the field of power grid informatization, in particular to a method for registering X-ray images of power equipment. Background technique [0002] X-ray digital imaging detection technology can conduct intuitive and convenient visual detection of common material, foreign matter and assembly defects in power equipment, and realize defect positioning and size measurement. It can be applied to integrated equipment such as plant GIS and power transmission lines In the non-destructive testing of power equipment such as ground wires, fittings, insulators and underground cables, it plays a vital role in ensuring the safe and stable operation of power equipment. For combined power equipment such as GIS and tank circuit breakers, the structure is generally a closed tank with a large volume and composed of different materials, and the internal materials and structures are extremely complicated. Even for the same defect of the s...
