AI Technical Summary

Technical Problem

Existing technologies rely heavily on the analysis of insulator edge morphology, resulting in low recognition rates and poor accuracy, making it impossible to effectively determine the integrity of insulator equipment.

Method used

Image analysis methods are used to acquire the original image, identify the target rectangular region using a preset recognition model, perform multi-resolution curve transform to generate feature vectors, and compare them with the template feature vectors to determine whether the insulator is abnormal.

Benefits of technology

It improves the accuracy and effectiveness of insulator condition assessment, enabling simultaneous determination of insulator condition in both overall and detailed aspects.

Abstract

The present disclosure relates to the technical field of image analysis, and provides an image analysis method and device. The method comprises: acquiring an original image containing a target to be recognized; introducing the original image into a preset recognition model to recognize a target rectangular region; cutting a target sub-image from the original image based on the target rectangular region; performing multi-resolution curvelet transform on the target sub-image to generate a target feature vector; and comparing the target feature vector with a preset template feature vector to determine whether the target to be recognized in the original image is abnormal. The embodiments of the present disclosure can determine the state of the insulator in the whole and in the details synchronously, thereby greatly improving the accuracy and effectiveness of the analysis result.
