By installing a camera on an unmanned aerial vehicle, the image information of crops is collected, and images of large-scale crops are collected through the running track of the unmanned aerial vehicle. The image acquisition signal is then converted into an electrical signal, thereby improving the transmission of the signal, and then the acquired image signal is stored and sent through the control module.
