The present invention discloses an intelligently controllable fog screen projection system. The system comprises a fog screen generation module, a projection module, a control module, invisible light sources and an image acquisition device, wherein the fog screen generation module comprises a fog generation unit, a fog guide unit, a water filtering unit, a fog outlet and a side wall; the fog generation unit comprises a water tank and an ultrasonic wave integrated sprayer plate; the water filtering unit comprises a fog generation water fender; the fog guide unit comprises a fog guide fan, ventilation wall fans, a fog guide pipe and air guide pipes, and also comprises air velocity transducers and power adjusting modules, wherein outside air velocity information is detected by the air velocity transducers and sent to the control module, and the control module processes the air velocity data, controls rotating angles of the fog guide pipe and the air guide pipe according to the processed data, and controls the power adjusting modules to adjust output power of the fog guide fan and the ventilation wall fan. Influence factors of air velocity on fog screens are effectively compensated, the fog screen display effect is raised, and the intelligently controllable fog screen projection system is suitable for usage outdoors.
