Embodiment 1

[0068] Such as figure 1 As shown, an insulator image recognition method based on salient features, including:

[0069] S1: Perform a feature extraction operation on the collected insulator image to obtain the salient features of the insulator image;

[0070] S2: Using BP neural network to train the salient features to obtain an insulator image recognition model;

[0071] S3: Transmitting the newly collected insulator image to the insulator image recognition model to obtain a recognition result.

[0072] In this embodiment, an effective classifier for insulators is obtained through neural network learning. At the same time, the addition of salient feature processing to extract the appearance of the insulator image by using the contrast of the histogram effectively reduces a large amount of redundant data and information in the original image, and improves the follow-up process.

Description

technical field [0001] The invention relates to the field of image processing, in particular to an insulator image recognition method and system based on salient features. Background technique [0002] At present, insulator identification methods are mainly traditional manual on-site inspection and UAV aerial photography inspection. Manual inspection technology has high recognition accuracy, but information collection is difficult and inefficient. UAVs are used for inspection of transmission lines, although information collection is convenient. , but it is still necessary to manually inspect the collected images. Although this technology is more efficient than the traditional manual field inspection technology, it will also be affected by related factors, such as the influence of light when the UAV is shooting insulators and artificial long-term inspection. The detection of aerial images is prone to missed detection. [0003] Machine vision technology has the advantages of ...
