Quick orientating method of work space measuring and positioning system by standard rod

The invention provides a quick orientating method of a work space measuring and positioning system by a standard rod, which comprises the steps of: calibrating the standard rod; measuring the rotating angle values theta 1 and theta 2 of a rotating table of a transmitting station when two rotating laser planes transmitted out from the transmitting station respectively reach a receiver; obtaining the equation parameter of the rotating light plane equation of the two rotating laser planes transmitted out from the transmitting station under the self coordinate system according to the rotating angle values theta 1 and theta 2 of the rotating table of the transmitting station; and resolving the azimuth angle and the pitch angle of the receiver under the self coordinate system of the transmitting station, so that global orientation is realized, and the like. The method can be used for globally orienting independent of auxiliary equipment, and the positioning and the putting of a work space measuring and positioning system (WMPS) system are not strictly required when the method is used for orientation, so that the use cost of the system can be effectively reduced. One person can complete the field orientation of the WMPS system only within ten minutes by adopting the orientating method provided by the invention, so that the networking measurement efficiency of the WMPS system can be greatly improved, therefore, the quick orientating method is very suitable for industrial fields.
