Abstract
A 3-point positioning device senses a scene including an auxiliary positioning module by means of an image sensor, and accordingly generates a sensed image. The auxiliary positioning module comprises a first, a second, and a third auxiliary positioning units. By means of the sensed image, the 3-point positioning device recognizes a first, a second, and a third sensing units of the image sensor corresponding to the first, the second, and the third auxiliary positioning units. In this way, the 3-point positioning device can calculate out an absolute location of the auxiliary positioning module according to the locations or the received power of the first, the second, and the third sensing units.
