Electric power measurement wiring line anomaly detection method and system

The invention discloses an electric power measurement wiring line anomaly detection method and system, and belongs to the technical field of image recognition. The method comprises the following steps: acquiring image data of a wiring line of a metering device in an electric power metering operation process, determining a bounding box and abnormal data of the image data, marking image masks corresponding to the bounding box and the abnormal data in the image data, and generating training data; constructing an instance segmentation model of the wiring circuit of the metering device, and training the instance segmentation model based on the training data to construct a state classifier; and obtaining target image data of a wiring circuit of a target metering device, and based on the state classifier, identifying the target image data so as to detect abnormity of the wiring circuit of the target metering device. The whole wiring condition of the electric power metering device can be analyzed to judge whether the
