Image Tracking System and Image Tracking Method Thereof

An image tracking method, applicable in an image tracking system, and the image tracking system comprising an image capture module, a detection module and a processing module, and the image tracking method comprising the steps of:

• capturing a real-time image by the image capture module;
• analyzing the real-time image by the detection module;
• detecting whether positions of a plurality of instruments are disposed in the real-time image by the detection module;
• defining a buffer zone in the real-time image by the processing module;
• using the processing module to analyze whether the instruments are disposed in the buffer zone of the real-time image according to the positions of the instruments;
• using the processing module to calculate a spacing distance between the instruments and determine whether the spacing distance between the instruments is smaller than a first preset distance if the instruments are disposed in the buffer zone of the real-time image;
• and
• using the processing module to emit a controlling signal to control the image capture module to move to a capture position, if the spacing distance is greater than a second preset distance.
