Unmanned aerial vehicle line patrol image auxiliary acquisition method and system based on resolution reconstruction

[0049] see figure 1 , On the one hand, the present invention provides a resolution-based reconstruction-based UAV line inspection image auxiliary acquisition method, which uses the UAV onboard camera to collect images of designated inspection areas, and inputs the collected images to the onboard computer Equipment, in this embodiment, the unmanned aerial vehicle adopts the DJI unmanned aerial vehicle, and the onboard computing device adopts the Miaosuan microcomputer; the images and video data collected by the camera are transmitted to the Miaosuan in real time;

[0050] Miaosuan is equipped with a sharpness evaluation algorithm, a pre-trained resolution reconstruction model and a target detection model;

[0051]Miaosuan first preprocesses the image, and evaluates the sharpness of the input image through the sharpness evaluation algorithm. If the sharpness of the input image does not meet the set threshold, it will be judged as a low-resolution image and input to the RR-CNN ( Re

[0093] This embodiment provides a UAV line inspection image auxiliary acquisition system based on resolution reconstruction, including:

[0094] UAVs for image acquisition via on-board cameras;

[0095] A computing device, the computing device is connected to the airborne camera, and the computing device includes a preprocessing unit, a sharpness evaluation unit, a resolution reconstruction unit and a target detection unit;

[0096] The preprocessing unit is used to preprocess the image collected by the airborne camera and then output the value clarity evaluation unit;

[0097] The sharpness evaluation unit is used to evaluate the sharpness of the input image through a sharpness evaluation algorithm, and output the image whose sharpness does not meet the set threshold to the resolution reconstruction unit, and output the image that meets the set threshold to the target detection unit;

[0098] The resolution reconstruction unit uses the resolution reconstruction model based on

[0102] This embodiment provides a resolution-based reconstruction-based UAV line patrol image auxiliary acquisition device, including a memory, a processor, and a computer program stored on the memory and operable on the processor, and the processor executes the program implement the auxiliary acquisition method as described in any embodiment of the present invention.
