Transmission Cable Model Identification Based on Dual-Stage Correction
摘要
Abstract
Identifying and accurately reading transmission cable models is a key task in power system equip-ment management and operation maintenance.In order to solve the problems of low detection accuracy and slow speed of existing methods in transmission cable scenes with complex bending patterns and strong background interference,a transmission cable model identification method based on dual-stage correction is proposed.First-ly,region-level segmentation is used to accurately extract the text region location.Secondly,a dual-stage correc-tion strategy is designed,which adopts thin plate spline(TPS)interpolation to achieve coarse correction,and completes fine correction through offset mapping,so as to optimize the geometrical distribution of the text.Fi-nally,an attention-based feature optimization mechanism is incorporated in the recognition module,which en-hances the recognition ability for irregular and fuzzy text.The experimental results show that the proposed method performs well on the self-constructed transmission cable dataset and the publicly available datasets CO-CO-Text and CTW-1500,with an average recognition accuracy improvement of more than 2.7％over some of the traditional method.Meanwhile,its recognition accuracy reaches 85.3％in high reflection and complex background scenes,achieving an effective balance between detection efficiency and recognition accuracy.关键词
