Abstract: A system for 3D online sports athletics includes: a cloud server and several head-mounted devices, wherein each of the head-mounted devices is paired with an intelligent terminal having a step counting function. A 3D scene virtualizing unit virtualizing a 3D online sports athletics scene to display the virtualized objects of all the head-mounted device users. A wirelessly connecting unit wirelessly connecting the intelligent terminal that it is paired with and the cloud server. A processing unit acquiring step counting data of the intelligent terminal and uploading the step counting data to the cloud server, and acquiring the step counting data of other head-mounted devices from the cloud server, driving the 3D scene virtualizing unit to display online the step counting data of each of the head-mounted device users in its 3D online running athletics scene, to realize sports athletics where a plurality of persons are simultaneously online.

Abstract: Embodiments of the present disclosure disclose a head-wearable apparatus, a 3D video call system and a method for implementing 3D video call. The present disclosure relates to virtual reality technologies and is invented to relatively completely shoot video images of the scenario where the user locates, achieve real-time 3D video call between users of both parties, and mutually share scenes viewed by themselves. The head-wearable apparatus comprises at least two cameras which are spaced apart from each other and arranged on the head fixing means and/or the video output unit, and field of vision of the at least two cameras superimposes and covers all positions in a horizontal direction.
