Abstract: A target tracking system includes an observation module, a dynamic tracking module, a control module and an aiming module. The observation module captures an observation frame including a tracked-object image of a tracked-object and an aiming point image and detects a distance between the observation module and the tracked-object. The dynamic tracking module analyzes the observation frame to obtain a lag correction vector between the aiming point image and the tracked-object image, and obtains a feed-forward correction vector according to the lag correction vector and the distance. The control module generates a control command representing the lag correction vector and a control command representing the feed-forward correction vector. The aiming module moves according to the control commands to control the aiming point image to align with the tracked-object image and control the aiming point image to lead the tracked-object image.
