The invention discloses a moving object tracking method applied to human-computer interaction. The moving object tracking method comprises the steps of capturing images, and determining an initial position of an object in the current image; performing LK light stream tracking on an object region in the current image to obtain a tracking result frame; detecting the current image through a training classifier to obtain a detection result frame; computing credibility of the detection result, and determining a final position of the object and initial information for LK light stream tracking of the next image according to the credibility. By means of the moving object tracking method, an object detection method can be utilized in a differentiated mode under different conditions, and detection and tracking are combined to perform real-time high-efficiency tracking of the dynamic object. The moving object tracking method is universal, suitable for various human-computer interaction scenes and capable of performing r
