Detection device and detection method for metal corrosion of power transformation equipment

Abstract

The invention discloses a detection device and a detection method for metal corrosion of power transformation equipment. The detection device comprises a sample collection module, a layered nesting labeling module, a target detection model training module and a detection result integration module which are connected in sequence; the sample collection module is used for a power transformation equipment sample with a corrosion defect; the layered nested labeling module is used for labeling samples and dividing the samples into a training set, a verification set and a test set; the target detection model training module adopts the marked training set to train a target detection model to obtain a transformation equipment corrosion detection model; and the detection result integration module combines all intersected detection frames in the detection result. Compared with a target detection model obtained by training through a traditional labeling method, the device and method have higher detection rate and recall rate in substation equipment corrosion detection.

Description

technical field [0001] The present invention relates to the field of target detection, in particular to a detection device and a detection method for metal corrosion of substation equipment. Background technique [0002] Substation equipment is prone to metal corrosion due to long-term exposure to the outdoor environment. In order to avoid potential safety hazards and prolong the service life of equipment, it is necessary to detect and intervene as soon as possible. The automatic detection method of metal corrosion images based on deep learning is currently a feasible method, but due to the irregularity and detachability of metal corrosion shapes, the traditional single rectangular box data labeling method often has corrosion detection in the trained model The problem of low precision and recall. Contents of the invention [0003] Purpose of the invention: The purpose of the present invention is to provide a detection device and detection method for metal corrosion of sub...
