Abstract
A laser positioning system includes a laser scanner, a first positioning tag, a second positioning tag, and a processing unit. The laser scanner is disposed on a mobile carrier and is for emitting a light beam to a positioning board and receiving a plurality of reflected light spot signals generated by the light beam reflected from the positioning board. The first positioning tag and the second positioning tag are for reflecting the light beam to generate a first positioning signal and a second positioning signal to the laser scanner. The processing unit is for finding information of positions of the light beam projected on the first positioning tag and the second positioning tag, and filtering the reflected light spot signals to define a reference coordinate for the processing to calculate relative positions of the laser scanner and the positioning board according to the reference coordinate.
