Wind strength is measured in-flight with IMU/GPS calculations and is visualized inside C³P control software for flight purposes. However, the wind on the ground should be measured with anemometer before each flight and should be less than 8 m/s for stable flight and stable video image.
NOTE: Wind is always stronger higher in the air because of the wind gradient. If speed on the ground is 3 m/s you can assume 5 m/s at 100 m AGL.
