The present disclosure may provide a method for movement control. The method may include obtaining at least one tracking parameter associated with a moving object and a control algorithm including a first control algorithm and a second control algorithm associated with a capture device used to track the moving object. The method may also include determining a switching time point with respect to the first control algorithm and the second control algorithm. Further, the method may include accelerating, according to the first control algorithm, a speed of the capture device within a first acceleration time period from a start time point to the switching time point and accelerating, according to the second control algorithm from the switching time point to an acceleration termination time point.
