The invention relates to the technical field of
power grid image classification, in particular to an image classification method based on a
semantic knowledge base in a
smart power grid, and the method comprises the following operation steps: S1, data collection: 1.1, collecting image data from various devices (such as a monitoring camera and unmanned aerial
vehicle inspection equipment) of the
smart power grid; the images may include the appearance of the
power equipment, the operation state (such as the
oil temperature indication of a
transformer and the on-off state of a switch), and the integrity of the line. 1.2, preliminarily preprocessing the acquired images, including unifying the format of the images (for example, converting the images into a
JPEG (Joint Photographic Experts Group) format), adjusting the size (enabling the images to adapt to a subsequent
processing algorithm, for example, uniformly adjusting the images into 512 * 512 pixels) and removing
noise (removing
salt and pepper noise in the images by using a filtering technology, for example,
Gaussian filtering); according to the method, the
feature extraction process can be guided through the
semantic knowledge base, so that the model focuses on key features related to
semantics, and the classification precision can be improved.
