Abstract:
A coordinate positioning system with in-the-air positioning function includes an illuminator and an image sensor. The illuminator produces a directional light. The image sensor receives the directional light produced by the illuminator and produces an image corresponding to the directional light to accordingly analyze the image and obtain a rotating angle corresponding to the directional light.
