Embodiment 1
[0068] see figure 1 , figure 1 It is a schematic flowchart of an insulator identification method based on infrared hotspot tracking disclosed in an embodiment of the present invention. figure 1 The described method can be applied to inspection equipment of transmission lines. Such as figure 1 As shown, the insulator identification method based on infrared hot spot tracking may include the following steps:
[0069] 101. The inspection equipment analyzes all the temperature values of the infrared images collected by the infrared camera, and judges whether there is a target temperature value higher than the preset temperature threshold in all the temperature values of the infrared images. If yes, perform step 102, if not , to end this process.
[0070] In the embodiment of the present invention, the temperature measurement algorithm has been integrated in the hardware of the infrared camera, and the temperature value of each pixel in the infrared image can be directly obt...

[0114] see Figure 4 , Figure 4 It is a schematic flowchart of another insulator identification method based on infrared hotspot tracking disclosed in the embodiment of the present invention. Such as Figure 4 As shown, the insulator identification method based on infrared hot spot tracking may include the following steps:
[0115] Wherein, steps 201 to 202 are the same as steps 101 to 102, and the following content will not be repeated.
[0116] 203. The inspection device judges whether the high-temperature target is located in the central area of the infrared image, if yes, execute step 204, and if not, execute step 205-step 207.
[0117] 204. The inspection equipment extracts the directional gradient histogram feature of the infrared image, and uses the AdaBoost classifier to identify whether the high-temperature target contains insulators according to the directional gradient histogram feature of the infrared image. If it does, perform step 208. If not, end this arti...
