The invention provides an artificial intelligence-based jelly effect prevention method and system in an aerial photography scene, and relates to the field of artificial intelligence. The method comprises the steps that a rolling shutter camera collects an image; optical flow information of the image is obtained through an optical flow method, and moving pixel points and static pixel points in the image are obtained according to the optical flow information of the image and the flight speed of the unmanned aerial vehicle; the method also includes obtaining a jelly effect index according to the optical flow information of the static pixel points as a label of a time sequence prediction network to train the time sequence prediction network; inputting the flight speed of the unmanned aerial vehicle, the shutter time of the camera and the reading of the IMU into a time sequence prediction network to predict a jelly effect index of a future frame image; and constructing dynamic characteristics of the image, and determining an adjustment mode and timely adjusting related parameters of the unmanned aerial vehicle according to a jelly effect index obtained by the time sequence prediction network and the dynamic characteristics of the current frame. According to the invention, quality prediction of the shot image is realized, parameters of the unmanned aerial vehicle are adjusted in time to prevent a jelly effect, and high-quality images are acquired.
