1. A method for computer-implemented monitoring of one or more wind turbines in a wind farm, each wind turbine having a rotor with rotor blades which are rotatable by wind around a rotor axis, wherein one or several times during the operation of the wind farm a process is performed comprising the following steps for a respective rotor blade of one or more rotor blades of a respective wind turbine of the one or more wind turbines:
i) obtaining a digital image of the respective rotor blade, the digital image being a current image taken by a camera looking at the respective rotor blade; and
ii) determining one or more operation characteristics of the respective rotor blade by processing the digital image by a trained data driven model, where the digital image is fed as a digital input to the trained data driven model and the trained data driven model provides the one or more operation characteristics of the respective rotor blade as a digital output;
wherein the camera is installed on another wind turbine than the respective wind turbine for which the process is performed.
