Method and system for 3D online sports athletics

A system for 3D online sports athletics, comprises:

• a cloud server and several head-mounted devices having a virtual reality function, wherein each of the head-mounted devices is paired with an intelligent terminal having a step counting function, and each of the head-mounted devices is assigned a unique ID in the cloud server, and is under centralized management by the cloud server;
• the several head-mounted devices comprise one master head-mounted device, and other head-mounted devices than the master head-mounted device are slave head-mounted devices;
• the master head-mounted device is configured to, at starting of the sports athletics, determine slave head-mounted devices that participate in the sports athletics, and send IDs of all the head-mounted devices that participate in the sports athletics and a preset competition rule to the cloud server, wherein the competition rule comprises sports scene, time and distance;
• each of the head-mounted devices comprises a 3D scene virtualizing unit, a wirelessly connecting unit and a processing unit;
• the 3D scene virtualizing unit is configured to, at the starting of the sports athletics, virtualize a 3D online sports athletics scene to display virtualized objects of all head-mounted device users that participate in the sports athletics;
• the wirelessly connecting unit is configured to, during the sports athletics, wirelessly connect the intelligent terminal that it is paired with and the cloud server;
• and
• the processing unit is configured to acquire, via the wirelessly connecting unit, in real time, step counting data of the intelligent terminal that it is paired with, upload in real time the acquired step counting data to the cloud server, and acquire the step counting data of other head-mounted devices from the cloud server;
• and drive the 3D scene virtualizing unit to display online the step counting data of each of the head-mounted device users in its 3D online sports athletics scene, to realize sports athletics where a plurality of persons are simultaneously online.
