Embodiment Construction
[0039] The present invention will be further described in detail below in conjunction with the accompanying drawings.
[0040] The present invention provides an image classification method for on-line monitoring of the state of power transmission and transformation equipment, the method comprising the following steps:
[0041] Step 1: Label the positive and negative samples;
[0042] Step 2: Extract feature data values to form an original training sample set;
[0043] Step 3: get the classification model;
[0044] Step 4: Perform 5-fold cross-validation on the classification model;
[0045] Step 5: Real-time classification of status images of power transmission and transformation equipment.
[0046] The positive and negative sample images in the step 1 are derived from aerial photography and infrared inspection images, and images showing normal device status are selected as positive samples, and images showing abnormal device states are selected as negative samples.
