1. A system, comprising:
at least one storage device including a set of instructions; and
at least one processor in communication with the at least one storage device, wherein when executing the set of instructions, the at least one processor is configured to cause the system to:
obtain at least one tracking parameter associated with a moving object;
obtain a control algorithm including a first control algorithm and a second control algorithm associated with a capture device used to track the moving object, wherein the first control algorithm includes an exponential algorithm or T-shaped algorithm and the second control algorithm includes an S-shaped algorithm;
determine a switching time point with respect to the first control algorithm and the second control algorithm based on the at least one tracking parameter;
accelerate, according to the first control algorithm, a speed of the capture device from an initial speed to a first speed within a first acceleration time period from a start time point to the switching time point, the capture device moving a first acceleration distance within the first acceleration time period; and
accelerate, according to the second control algorithm, the speed of the capture device from the first speed to a second speed within a second acceleration time period from the switching time point to an acceleration termination time point, the capture device moving a second acceleration distance within the second acceleration time period, wherein at least one of a moving distance of the capture device or the second speed satisfies the at least one tracking parameter, the moving distance of the capture device being determined based at least in part on the first acceleration distance and the second acceleration distance.
