The invention relates to an ultrasonic three-dimensional positioning system for realizing six-degree-of-freedom measurement and an ultrasonic three-dimensional positioning method for realizing six-degree-of-freedom measurement, and belongs to the ultrasonic three-dimensional positioning method. The system comprises transmitting devices and receiving devices. The receiving module first receiving the ultrasound is called the target module, and the remaining two receiving modules are called the target nodes. The time difference of the moment of receiving the ultrasonic waves of the target nodes and the target module is measured when the ultrasonic waves are transmitted by different transmitting modules so that the distance difference from the transmitting modules to the target nodes and the target module is solved when the ultrasonic waves are transmitted by different transmitting modules. Positioning of the transmitting modules is realized by calculating the coordinate values of the transmitting modules, and th
