1. A tracking method, comprising:
capturing a plurality of images by a tracking camera;
tracking a first position of a trackable device within the images;
using the previously tracked first position of the trackable device to determine an object-related area in a region adjacent to the first position;
recognizing an object in the object-related area around the first position of the trackable device in the images; and
in response to the object being recognized, tracking a second position of the object in the images;
wherein the step of recognizing the object in the object-related area around the first position of the trackable device comprises:
dividing each of the images into the object-related area adjacent to the first position of the trackable device and a background area; and
searching the object-related area in each of the images for the object based on a computer vision algorithm.
