Abstract
The invention discloses a target robust detection and defect identification method for the nuts and pins of a power grid. The method comprises the following steps of acquiring and screening a target picture set through an image acquisition module; labeling and storing the target picture set; constructing a deep learning model to form a training model; and detecting and identifying an augmented picture according to the training model. The invention further provides a target robust detection and defect recognition device for the nuts and pins of the power grid. At the training stage of a detection model, a deep neural network model training technology when the strabismus nut and pin samples are few is studied, and the automatic detection and defect identification of the robust strabismus with insufficient and unbalanced nut and pin samples are realized by utilizing a strabismus training data augmentation method based on perspective transformation.
Description
technical field [0001] The invention relates to the technical field of computer vision recognition, in particular to a method and device for robust detection and defect recognition of grid nuts and pins. Background technique [0002] China's geographical environment is relatively complex and its climate varies greatly. Many transmission lines are installed in harsh environments, such as lakes and forests. Ensuring the safety and stability of transmission lines is a very important content and a prerequisite for the safe and intelligent construction of power grids. Pins and nuts play a non-negligible auxiliary role in the line. In the transmission line, the main function of the pin and nut is to fix large fittings, such as clamps, anti-vibration hammers, pressure equalizing rings, and connecting fittings. Due to the complex environment, the pins and nuts are prone to rust, drop, and damage, which in turn affects the stable operation and work of the above large hardware. Th...
