Intelligent high-altitude power inspection vision module based on KendryteK210 microcontroller

Abstract

Now our country has a huge electric power system, it needs a complex electric power transmission network to support its normal operation. With the development of unmanned aerial vehicle platform and microprocessor technology in recent years, the unmanned aerial vehicle inspection platform based on microprocessor is an important development direction of power transmission network maintenance. Based on this background, this paper designs an intelligent high-altitude line inspection vision module based on KendryteK210 microcontroller. The module can be used as a UAV load to carry out efficient power line patrol work, and wireless communication is carried out by ESP8285Wi-Fi. First of all, the inspection vision module uses OV2640 visible light camera to complete the target image data acquisition. Then, in the process of data processing, the least square method and Theil-Sen regression algorithm are combined to get the target line object, so as to get the slope and length of the line object and other parameters. Finally, the target in the image was identifi ed based on the yolov2 neural network model, and then the fl ight path instruction was provided for the UAV platform.
