Abstract
A visual identification positioning system includes a first positioning member, a second positioning member, and a mowing robot. The mowing robot has a visual identification unit and a computation unit. The visual identification unit identifies a first identification feature of the first positioning member and a second identification feature of the second positioning member to generate first and second signals to the computation unit. The computation unit computes a first coordinate, a second coordinate, a first distance between the mowing robot and the first coordinate, and a second distance between the mowing robot and the second coordinate according to the first and second signals, and defines first and second ranges with the first and second coordinates as centers according to the first and second distances, and computes a coordinate of an intersection of the first and second ranges as a current location coordinate of the mowing robot.
