Detailed Description
In order to make the present invention better understood by those skilled in the art, the following description will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings, and it is apparent that the described embodiments are only some embodiments of the present invention, not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
For easy understanding, referring to fig. 1, an embodiment of a method for detecting rust defects of a damper of a power transmission line according to the present invention includes:
step 101, constructing a transmission line anti-vibration hammer image sample data set, wherein the transmission line anti-vibration hammer image sample data set comprises a rust defect image data set and a normal image data set.
In the embodiment of the invention, the rust defect image data set and the normal image data set are acquired first, and the vibration damper image sample data set of the power transmission line is constructed. The method comprises the steps of selecting an image containing the damper from an unmanned aerial vehicle inspection image, preprocessing the image, cutting the image into preset sizes such as 800 multiplied by 800, and classifying and labeling the rust defect image and the normal image, so that a real power transmission line damper image data set is constructed. In order to realize the comprehensiveness of the rust defect image sample, the rust defect image sample can be subjected to sample expansion, specifically, a generated countermeasure network model is trained based on a real power transmission line damper image data set, the generated countermeasure network model is a SinGAN network model, an image containing damper rust defects in the real power transmission line damper image data set is based on the trained generation network in the generated countermeasure network, and a power transmission line damper image containing damper rust defects is generated. Therefore, the image data set of the rust defect formed by the image containing the rust defect of the damper in the real power transmission line damper image data set and the power transmission line damper image containing the rust defect of the damper generated by the generation network can be obtained. And the image which does not contain the vibration damper rust defect in the real power transmission line vibration damper image data set is classified as a normal image data set.
Step 102, replacing a CBS module of a C2f module in the Yolov8s detection model by an EESP module in the ESPNetv2 model, replacing a SiLU activation function in a convolution module playing a role in downsampling in a backbone network in the Yolov8s detection model by a PReLU activation function, and replacing a CBS module of a head network in a feature pyramid of the Yolov8s detection model by downsampling operation and standard convolution of 1×1 to obtain an improved Yolov8s detection model.
It should be noted that, in the embodiment of the present invention, the conventional YOLOv8s detection model is improved, the EESP module in the ESPNetv2 model with a smaller parameter is used to replace the CBS module of the C2f module in the YOLOv8s detection model (the CBS module is composed of a 3x3 standard convolution+batch normalization+silu activation function), the prerlu activation function with a lower computational complexity is used to replace the SiLU activation function in the convolution module playing the role of downsampling in the backbone network in the YOLOv8s detection model, and the downsampling operation and a 1 x 1 standard convolution are used to replace the CBS module of the head network in the YOLOv8s detection model feature pyramid (a 3x3 standard convolution+batch normalization+silu activation function with a step length of 2), so as to obtain the improved YOLOv8s detection model.
Specifically, as shown in fig. 2, the network structure of the EESP unit module in the present invention has 4 parallel deep hole separable convolution modules, and the hole rates are 3,5,7 and 3 respectively. In fig. 2, H and W are the width and height of the input feature map, respectively, ci is the number of input channels of the input feature map, co is the number of output channels of the output feature map, s is the convolution kernel size, and r is the void fraction. The principle is as follows: firstly, processing input features by using a 1 multiplied by 1 point group convolution, adjusting the number of channels to Co/4, facilitating cross-channel feature information interaction, using a batch normalization layer to avoid network over fitting, and using a ReLU activation function to increase nonlinear expression capacity of the network. And then, extracting the features by using the depth hole separable convolutions of different receptive fields (namely four 3x3 depth hole separable convolutions with the hole rates r of 3,5,7 and 3 in fig. 2), so that the receptive fields of the network are effectively increased, and the network is facilitated to extract more effective feature information. And then combining and splicing the features extracted from different receptive fields to integrate effective feature information. And then, carrying out information fusion (the number of channels is unchanged) on the fused features by using a 1X 1 point group-by-point convolution, connecting the generated features with the input features through a shortcut, effectively utilizing the original effective feature information, and finally, increasing the nonlinear expression capacity of the module through a PReLU activation function to obtain an output feature map.
The network structure of the improved YOLOv8s detection model obtained in the invention is shown in fig. 3, a convolution module con_p_3 in the main network has the function of downsampling, the channel number is adjusted, and finally, a characteristic diagram is generated (the characteristic diagram sizes are respectively 100×100×256, 50×50×512 and 25×25×512). The c2f_1 and c2f_2 modules (in the backbone network) play a role in feature extraction, extracting valid features. The SPPF module is used for realizing fusion of local features and global features. The up-sampling module is used for expanding the input feature map by two times, and generating the feature map through two up-samplings (the feature map sizes are respectively 50×50×512 and 100×100×256). The feature map 100×100×256 generated by the upsampling operation and the feature map 100×100×256 generated by the con_p_3 module are subjected to feature fusion, and the fused feature map is input into the detection head (100×100×256). The two downsampling+1x1 standard convolution modules play a role in downsampling, the feature map 100×100×256 is adjusted to 50×50×512 after passing through one module, then the feature map 50×50×512 is adjusted to 25×25×512 after passing through the module again, and then the feature map 50×50×512 obtained after being respectively fused with the 50×50×512 feature map generated by the Con_P_3 module and the 50×50×512 feature map generated by the upsampling and the 25×25×512 feature map generated by the SPPF module are respectively input into the other two detection heads (50×50×512 and 25×25×512) through feature fusion. And finally, the detection head detects the rust defect of the vibration damper of the power transmission line according to the input characteristic diagram.
The total of 8C 2f modules in the traditional YOLOv8s detection model has 16 standard convolutions of 3 multiplied by 3, the corresponding 8C 2f modules in the improved YOLOv8s detection model has 64 depth holes with 3 multiplied by 3, the standard convolutions of 3 multiplied by 3 have the parameters of 9 multiplied by the number of output channels and 3 multiplied by 3, and the receptive field is 3 multiplied by 3; the parameter quantity of the separable convolution of each 3 multiplied by 3 depth hole is 9 multiplied by the number of input channels and the number of input channels multiplied by the number of input channels, and the receptive field is (2 multiplied by the void ratio+1) multiplied by (2 multiplied by the void ratio+1); the minimum input/output channel number of the C2f module in the Yolov8s model is 128, so that the improved model parameter is far lower than that of the traditional Yolov8s detection model; and the void ratio in the improved model is 3,5,7 and 3 respectively, so that the improved model receptive field is larger than that of the traditional YOLOv8s detection model, and the characteristics can be extracted more effectively.
And step 103, training the improved YOLOv8s detection model according to the transmission line damper image sample data set to obtain a target detection model.
The improved YOLOv8s detection model is trained by using the transmission line damper image sample data set. Specifically, the improved YOLOv8s detection model is pre-trained by using a Gogle Open Image public data set, model parameters obtained by pre-training are used as initial parameters of the improved YOLOv8s detection model, and then the pre-trained improved YOLOv8s detection model is trained by using a transmission line damper Image sample data set to obtain a target detection model. When the pre-trained improved YOLOv8s detection model is trained by using the transmission line anti-vibration hammer image sample data set, the transmission line anti-vibration hammer image sample data set can be divided into a training set and a testing set according to a preset proportion, the improved YOLOv8s detection model is trained by using the training set, and the improved YOLOv8s detection model is tested by using the testing set.
And 104, inputting the transmission line image to be identified and containing the damper into a target detection model to obtain a transmission line damper rust defect detection result.
It should be noted that, after the target detection model is obtained in step 103, the transmission line image to be identified containing the damper is input into the target detection model, so as to obtain the detection result of the rust defect of the transmission line damper, that is, whether the damper in the transmission line image to be identified containing the damper has the rust defect and the specific rust defect position are identified.
