The present disclosure discloses a method and system for positioning an engineering machinery work object. The method comprises: a reference station collects in real time satellite positioning information as a reference station current measurement value D0, and transmits D0 to first and second mobile stations; the first mobile station and the second mobile station respectively collect in real time satellite positioning information as a first mobile station current measurement value D1 and a second mobile station current measurement value D2, and respectively perform dynamic differential processes on D0 and D1 and D0 and D2 to obtain relative coordinate information of the first mobile station and the second mobile station; a crane resolving unit determines the boom extension length, the boom pitch angle and boom rotating angle based on the relative coordinate information of the first mobile station and the second mobile station; based on the boom extension length, the boom pitch angle and the boom rotating angle, a crane controller controls the boom to move to a hoisting position of the object to hoist the object. The present disclosure can greatly increase the precision of positioning the work object, and can also automatically track the boom to avoid errors and risks resulting from visual adjustment.
