Specific embodiment
To make the technical problem to be solved in the present invention, technical scheme and advantage clearer, below in conjunction with accompanying drawing and tool
Body embodiment is described in detail.
The present invention is applied to the scene that somatic sensation television game is carried out in VR equipment, wherein, somatosensory device is connected with service end, clothes
Business end is connected with VR equipment by network, as shown in Figure 1.Heretofore described service end both can be server, it is also possible to
It is PC, somatosensory device is the equipment for referring to gather human body attitude data, such as body-sensing video camera, and network connection is preferably nothing
Line network connection, VR equipment refers to Android or IOS the end equipments (class such as the VR one head comprising mobile phone, built-in process chip is aobvious
Like equipment etc., the present invention and with the statement of VR equipment).
On the one hand, the present invention provides a kind of method that human body attitude is superimposed with virtual scene, and the method for the present invention is applied
Service end, as shown in Fig. 2 including：
Step 100：Obtain the human body attitude data that somatosensory device is collected.
In this step, somatosensory device, preferably 3D body-sensings video camera, it can realize immediately dynamic seizure, image identification,
The functions such as microphone input, speech recognition, community interactive.Somatosensory device gathers human body attitude data, and sends it to service
End.
Step 200：It is human body key point data by human body attitude data preparation.
The data volume of the human body attitude data of somatosensory device collection is huger numerous and diverse, be unfavorable for transmitting and use, it is necessary to
Detected, screening and filtering, it is human body key point data then to arrange, and human body key point data can simulation human body appearance very well
State.
Step 300：Human body key point data are converted into a character string.
Human body key point data data form be unfavorable for network transmission, in order to improve efficiency of transmission, can by its according to
Certain rule is organized into a character string.
Step 400：Character string is sent to VR equipment, so that character string parsing is human body key point data by VR equipment,
And be synchronized on virtual portrait.
After VR equipment receives character string, human body key point data is resolved to again, be synchronized to virtual in virtual scene
On personage, virtual portrait is set to make corresponding action (action of i.e. extraneous human body).In virtual scene, virtual portrait can be with
Element in scene carries out interaction, reaches the purpose that human body attitude and virtual scene are overlapped.
The method that human body attitude of the invention is superimposed with virtual scene utilizes the mechanism of network service, by VR equipment and service
A LAN is set up between device, somatosensory device is connected to service end and carries out input data collection, while service end will be adopted again
The data for collecting are sent to VR equipment by LAN, and last VR equipment synchronizes to the data for collecting and represents and update,
The action of virtual portrait is controlled, is overlapped with virtual scene, and interaction is carried out with the element in scene, enrich virtual reality neck
The interest that domain is applied and played.
And the present invention is capable of identify that the human action of complexity, separately using the attitude of human body key point digital simulation human body
Outward, human body key point data are converted to character string and are transmitted by the present invention, improve efficiency of transmission, reduce network delay,
Real-time is good.
In order to preferably characterize human body attitude, human body key point data bulk is in 25, including whole body basic point, vertebra
Heart point, neck, head, left shoulder, left elbow, left finesse, left hand, right shoulder, right elbow, right finesse, the right hand, left stern, left knee, a left side
Ankle, left foot, right stern, right knee, right ankle, right crus of diaphragm, shoulder central point, left finesse, left hand refer to, right finesse, the right hand refer to.Above-mentioned 25
Key point is mainly human joint pointses or skeletal structure, and 25 key points (artis, skeletal structure) can simulate human body
Most limb actions and form.
Foregoing character string can have various data forms, it is preferred that character string includes present frame human body in world coordinates
Position data, 25 position datas of key point of present frame human body, the position data of present frame human hands under system.Wherein will
It is convenient in order to do gesture identification that the data of hand individually send.World coordinate system, i.e., with personage position as the origin of coordinates,
Relative position of other objects relative to the point.
Data form is as follows：
km,1.000,0.000,0.000,0.000,0.000,1.000,0.000,1.000,0.000,0.000,1.000,
0.000,0.000,0.000,0.000,1.000|
kb,26300644264040000,6,25,0,0,0,0,0,0|
kh,26300644264040000,6,0,0,0,0,0,0
