Based on the confidence scores, the target loss status is determined. A recapture operation is performed on the lost target; if recapture is successful, tracking resumes and parameters are updated; if recapture fails and times out, the target is removed from the queue. This process filters to obtain a set of trackable targets. The gimbal aiming point is determined by combining the current scene type and the predicted bounding boxes of each target. Control commands are generated based on the deviation between the aiming point and the image center to drive the gimbal rotation and calibration.
