Abstract | The invention discloses a method for detecting and identifying internal defects of an in-operation high-voltage cable through X-ray digital imaging, which comprises the following steps of: (1) starting an X-ray detection system, and acquiring an original image of a sequence X-ray detection cable; (2) rejecting improper pictures; (3) identifying contour lines of different material areas by using gray level step, and extracting images of different areas of the cable; (4) de-noising the images of the different regions by adopting a bilateral filtering optimization algorithm; (5) after the X-ray detection image is subjected to denoising processing, sequence images are subjected to multi-frame superposition, and the graphic morphological characteristics of the gray difference area are detected; and (6) establishing a high-voltage cable defect database according to the fault and detection data, and performing judgment according to comparison between the established high-voltage cable internal defect feature informa |
