Example 1
The application provides an infrared thermal imaging-based power equipment fault detection method, which is shown in fig. 1 and comprises the following steps:

In this embodiment, as shown in fig. 2, the preprocessing step of step S1 is as follows:
s11: the normalization operation is performed on the data set, and the step aims at normalizing the infrared thermal imaging data in the data set to ensure that the numerical range of the infrared thermal imaging data is in a uniform interval for subsequent processing. Normalization can be achieved by:
calculating the minimum value and the maximum value of all data in the data set;
the following formula is applied to normalize each data point in the dataset: normalized_value= (original_value-min_value)/(max_value-min_value), where original_value is the original value and min_value and max_value are the minimum and maximum values of the dataset.
S12: and carrying out histogram equalization operation on the image to improve the contrast ratio, wherein the histogram equalization can lead the pixel value distribution of the image to be more uniform, thereby improving the contrast ratio of the image. This step may be accomplished in the following manner:
converting an input image into a gray scale image;
calculating a histogram of the gray image to obtain the frequency distribution of each pixel value;

S13: filtering using the gaussian-laplace operator, enhancing the details and superimposing, this step aims at enhancing the details of the image while reducing noise. The method can be carried out according to the following steps:
gaussian filtering is applied to the normalized and histogram equalized image to reduce noise;
applying a laplacian operator to the gaussian filtered image to enhance details of the image;
and superposing the image enhanced by the Laplacian operator with the original image so as to preserve the characteristics of the original image.
In this embodiment, in step S2, the preprocessed image is labeled and divided into a training set and a test set, the Filter, the Batch Size, the learning rate, the regularization parameters, the adjustment of the model structure and the enhancement of the data thereof of the YOLOV5 model are input into the YOLOV5 model after the adjustment for training, the '. Pt' model file is generated, and the '. Pt' model file is converted into the model file based on the PyTorch frame.
In the embodiment, in step S3, the image size of the collected real-time infrared thermal imaging data is set to 256×256, and the captured real-time infrared thermal imaging data is input into a YOLOV5 model based on a PyTorch frame to extract features, obtain feature graphs with different dimensions, predict, judge the possibility of belonging to a target class according to the predicted value, and judge whether early warning is needed. In a YOLOv5 model of the PyTorch, outputting boundary box position and category information of target detection in a prediction stage, wherein each boundary box is provided with a confidence coefficient score and category probability in the output prediction value, and the prediction comprises calculation of coordinate loss, category loss and confidence coefficient loss;
the coordinate loss is used for measuring the difference between the predicted boundary frame position and the actual boundary frame position, and the mean square error loss calculation is adopted, and the formula is as follows:
coordinate loss=1/N Σ [ for each sample ] (coordinate weight Σ [ for each bounding box ] (true position-predicted position)/(2))
The class loss is used for measuring the difference between the predicted class and the real class, and the cross entropy loss calculation is adopted, and the formula is as follows:
class loss = -1/N = -per sample Σper class [ (true class label × log (predicted class probability) + (1-true class label) × log (1-predicted class probability))
The confidence loss is used for measuring the difference between the confidence score of the prediction boundary box and the true confidence, and the mean square error loss calculation is also adopted, and the formula is as follows:
confidence loss = 1/N Σ [ for each sample ] (confidence weight Σ [ for each bounding box ] (true confidence-predictive confidence)/(2))
And the formulas of the mean square error loss and the cross entropy loss are respectively as follows:
wherein: n: sample number,Actual target value, (-) ->Target value of model prediction, C: category number, y ij : whether sample i belongs to category j (actual tag, 0 or 1), or +.>The model predicts the probability that sample i belongs to category j.
In this embodiment, prediction in the YOLOV5 model based on the pyrerch framework performs output of a predicted value by removing post-processing steps of low confidence prediction, decoding a prediction frame, non-maximum suppression, class probability filtering. Removing low confidence predictions, i.e., in YOLOv5, typically sets a threshold (e.g., 0.3 or 0.5) as the confidence threshold. All bounding boxes with confidence scores below this threshold will be filtered out, i.e. those targets with lower predicted confidence will be removed. The predicted frame position of the decoded predicted frame, YOLOv5 output, is relative to the size and coordinates of the input image. At the time of post-processing, the coordinates of these predicted frames are decoded to obtain the actual position on the original image. Non-maximal suppression (NMS) is a technique used to eliminate redundant overlapping prediction blocks. Which IOU (Intersection over Union) overlaps the larger other prediction block. The class probability filtering, namely, for each prediction frame, selects the class with the highest class probability as the final target class, and outputs the final target class together with the confidence of the prediction frame. Finally, the YOLOv5 model outputs the position coordinates, class labels and confidence scores of the filtered and decoded prediction bounding boxes through a post-processing step. This information will help determine the categories of objects present in the input image and their location, thereby performing object detection and recognition tasks. The target class may cover: electric wires, electric workers, electric vehicles, utility poles, high voltage cables, transformers, electric towers, electric equipment.
