1. A method for intensifying identification of three-dimensional objects, the method comprising: utilizing a left eye camera and a right eye camera to capture a left eye image and a right eye image; calibrating the left eye image and the right eye image to generate a calibrated left eye image and a calibrated right eye image; utilizing the calibrated left eye image and the calibrated right eye image to generate a disparity map; differentiating a three-dimensional object from a background image according to the disparity map; projecting the three-dimensional object onto a plan view; filtering noise out of the plan view to generate a filtered three-dimensional object; determining whether the filtered three-dimensional object contains at least two three-dimensional objects; and separating the at least two three-dimensional objects when the filtered three-dimensional object contains at least two three-dimensional objects.
