Abstract

The invention discloses an external device positioning method and device, and a virtual reality device and system. The virtual reality device is provided with an ultrasonic transmitter. The external device is equipped with at least two ultrasonic receivers. The method comprises: ultrasonic signal information of at least two ultrasonic receivers is obtained, wherein the ultrasonic signal information includes distances between the at least two ultrasonic receivers and the ultrasonic transmitter and the ultrasonic signal intensity; according to the ultrasonic signal intensity, a first ultrasonicreceiver for locating an external device is determined between the at least two ultrasonic receivers; according to the distance between the first ultrasonic receiver and the ultrasonic transmitter, location information of the first ultrasonic receiver is determined; and on the basis of the location information of the first ultrasonic receiver, location information of the external device is determined. According to the embodiment of the invention, the accuracy of the location information of the external device is improved, so that the positioning effect of the external device is further improved.
