Description
Technical Field
The embodiment of the invention relates to the technical field of virtual reality, in particular to a method and a device for positioning a target object in a virtual space.
Background
Virtual Reality (VR) technology generally refers to computer simulation technology that can create and experience a Virtual world. The basic principle of VR system is as follows: a virtual scene is generated by a computer, and then a user is immersed into the virtual scene through a specific interaction device, so that the user is guided to generate an immersive sensation. The interactive device is here used to map objects or views in real space into virtual space before the user can observe virtual objects or views in virtual space. After the object in the real space is displaced, the interactive device needs to update the position of the virtual object corresponding to the object in the virtual space, so as to display the scene change to the user in real time.
In the prior art, when updating the position of a virtual object in a virtual space, a camera is generally used to directly take a picture of the object in a real space, then a large amount of operations are performed to obtain a new position and a new posture of the object in the real space, and finally the new position and the new posture of the object in the real space are mapped into the virtual space to obtain the new position and the new posture of the virtual object in the virtual space. The existing technical scheme for updating the position of the virtual object has huge data volume to be processed, and in actual operation, the virtual object position can be updated only by processing the data by a powerful data processor, and the efficiency of updating the position of the virtual object is very low, so that the real-time experience requirement of a user on a virtual scene can not be well met.
