Abstract
Description
Technical Field
[0001] This invention relates to the field of power system operation and maintenance technology, and in particular to a security monitoring method based on target image detection. Background Technology
[0002] With the development of power technology, power equipment defect detection technology is constantly being updated, among which image processing-based power equipment defect detection methods have received increasing attention. With the gradual maturation of computer vision technology and the continuous improvement of hardware technology, image processing-based power equipment defect detection methods have become a feasible and efficient technical means.
[0003] Existing techniques for detecting defects in power equipment typically involve collecting image data of the power equipment, analyzing the data, or comparing it with previous standard images to obtain analysis results. Based on these results, the presence of defects in the power equipment can be determined. However, in practical applications, changes in the natural environment and object placement at the location of the power equipment, along with the presence of numerous features in the collected images, can lead to significant errors during image analysis, making it difficult to accurately determine the presence of defects. Therefore, a security monitoring method based on target image detection has been developed. Summary of the Invention
[0004] The purpose of this invention is to provide a security monitoring method based on target image detection, so as to solve the problem that when the features of the image being analyzed differ greatly from the previous standard image, the analysis results are often erroneous.
[0005] This invention provides a security monitoring method based on target image detection, comprising:
[0006] Acquire power equipment monitoring image data and target image standard data, wherein the power equipment monitoring image data includes real-time acquired power equipment monitoring images and historical power equipment data;
[0007] The power equipment monitoring image data is analyzed to obtain the power equipment image data feature analysis results;
[0008] The target image is determined by matching the feature analysis results of the power equipment image data with the standard data of the target image.
[0009] Receive target image data within a preset time period, perform feature analysis on the target image data within the preset time period, and establish a target image environment template;
[0010] The real-time power equipment monitoring image data is compared with the historical power equipment image data. If the comparison results are significantly different, the real-time power equipment monitoring image data is used to extract features to obtain real-time image feature matching results. The real-time image feature matching results are then matched with the target image environment template to obtain target image environment template matching results.
[0011] The object features corresponding to the target image environment template in the real-time acquired power equipment monitoring images are removed to obtain the target equipment image. Defect detection is performed on the target equipment image to obtain the security monitoring analysis results of the target image detection.
[0012] Furthermore, power equipment monitoring image data and target image standard data are acquired. The power equipment monitoring image data includes real-time acquired power equipment monitoring images and historical power equipment data.
[0013] Image features are extracted from the historical data of the power equipment, and cluster analysis is performed on the image feature analysis results of the historical data of the power equipment to obtain the image feature analysis results of the historical data of the power equipment.
[0014] In the image feature analysis results of the historical data of the power equipment, the image analysis feature category is determined;
[0015] The real-time acquired power equipment monitoring images are processed by extracting features according to the image analysis feature categories, and the real-time acquired power equipment monitoring images are labeled according to the feature extraction results.
[0016] Further, the feature analysis results of the power equipment image data are matched with the target image standard data to determine the target image, including:
[0017] The target standard data includes image feature data of the monitored target power equipment and environmental feature data of the monitored target power equipment;
[0018] The analysis results of the power equipment image data are compared with the environmental feature data of the monitored target power equipment. If the difference in image features is within a preset range, the analysis results of the power equipment image data are matched with the image feature data of the monitored target power equipment.
[0019] If the analysis results of the power equipment image data are compared with the environmental feature data of the monitored target power equipment, and the difference in image features exceeds a preset range, then the corresponding power equipment is matched in the real-time acquired power equipment monitoring image based on the image feature data of the monitored target power equipment, and determined as the target power equipment.
[0020] Further, receiving target image data within a preset time period, performing feature analysis on the target image data within the preset time period, and establishing a target image environment template, including;
[0021] Establish dynamic preset time ranges. The time interval for the first preset time range is 3 seconds, the time interval for the second preset time range is 6 seconds, and the time interval for the third preset time range is 12 seconds.
[0022] The target image data is compared with the target image data collected in the previous time period. If the difference in image data is within the preset range, the third preset time period is started as the image acquisition frequency period.
[0023] After the third preset time period is used as the image acquisition frequency period for a preset number of times, the image acquisition frequency period is switched to the second preset time period range.
[0024] Furthermore, the object features corresponding to the target image environment template in the real-time acquired power equipment monitoring images are removed to obtain the target equipment image. Defect detection is performed on the target equipment image to obtain the security monitoring analysis results of the target image detection, including:
[0025] The real-time acquired power equipment monitoring images are compared with the target image environment template to obtain similar object features and different object features;
[0026] The approximate object features on the real-time acquired power equipment monitoring images are removed, and the real-time acquired power equipment monitoring images are analyzed again to obtain the target equipment image;
[0027] Defect detection is performed on the target device image to obtain the security monitoring analysis results of the target image detection.
[0028] The beneficial effects of this invention are as follows: This invention provides a security monitoring method based on target image detection, which acquires power equipment monitoring image data and target image standard data. The power equipment monitoring image data includes real-time acquired power equipment monitoring images and historical power equipment data. The method receives target image data within a preset time period, performs feature analysis on the target image data within the preset time period, establishes a target image environment template, removes object features corresponding to the target image environment template from the real-time acquired power equipment monitoring images to obtain target equipment images, performs defect detection on the target equipment images, and obtains security monitoring analysis results based on target image detection. By establishing an environment template, common noise object features are summarized and categorized. The real-time acquired image data is compared with the data in the environment template, achieving the effect of noise reduction of the real-time acquired image data and improving the accuracy of image data analysis results.

[0046] If the analysis results of the power equipment image data are compared with the environmental feature data of the monitored target power equipment, and the difference in image features exceeds a preset range, then the corresponding power equipment is matched in the real-time acquired power equipment monitoring image based on the image feature data of the monitored target power equipment, and determined as the target power equipment.
[0047] Specifically, receiving target image data within a preset time period, performing feature analysis on the target image data within the preset time period, and establishing a target image environment template, including:
