The invention discloses a low-
voltage ammeter fuzzy correction and detection method based on double-domain feature decoupling, and belongs to the crossing field of
computer vision and
power equipment intelligent detection. Aiming at the problems of dual-domain feature
coupling interference, multi-task cooperative defects, calculation efficiency restriction and the like in the prior art, three aspects of innovation are provided: a dual-domain feature decoupling
hybrid network (DDFDN) is constructed, local texture features are extracted through an asymmetric ConvNeXt
encoder of a
spatial domain branch, a
frequency domain branch AMSA decoder is combined with
frequency domain gating attention (FSAS) to maintain a
global structure, and a multi-task cooperative
algorithm is provided for solving the problems of dual-domain feature
coupling interference, multi-task cooperative defects, calculation efficiency restriction and the like. Multi-scale
feature fusion is realized by adopting a dynamic gating weight; designing a
frequency domain constraint and
semantic alignment mixed
loss function, and performing joint optimization through multi-band L1 constraint and detection network feature similarity; a lightweight YOLO-Element detection head is developed, and a rotation sensitive
convolution module and a frequency domain enhancement ROIAlign module are integrated. According to the method, the technical bottlenecks of a traditional method in the aspects of digital edge
recovery,
artifact suppression and multi-task cooperation are effectively solved, and a high-precision and low-
delay solution is provided for intelligent inspection of the electric meter in a complex scene.
