For an AGV to use the reflector as a reference for its own navigation, it must first obtain the coordinates of the field reflector.At present, the two-dimensional laser navigation scanner in the market has the calculation function of measuring the position coordinates of the field deployed reflector.The AGV only needs to be measured at the specified position, and the 360 degree rotation scanning function of two-dimensional laser scanner is used to obtain the position information of all reflectors in the current environment
