According to inaccuracy, the threedimensional model inaccuracy of MEC server foundation will cause, i.e. the effect of building profile is fine, and fills color lump
Poor effect.Therefore, whether MEC server needs judge accurate from the received two-dimensional video data of terminal, to guarantee to model
It is accurate.
With reference to the accompanying drawing and specific embodiment the present invention is described in further detail.
The embodiment of the invention also provides a kind of data processing methods, are applied to server, which is specially in Fig. 1
Shown in MEC server.Fig. 2 is the flow diagram of the data processing method of the embodiment of the present invention；As shown in Fig. 2, the side
Method includes:
Step 201: receiving the three dimensional video data of terminal acquisition.
Wherein, the three dimensional video data includes two-dimensional video data and depth data；The two-dimensional video data is used for
Flat image is characterized, such as can be RGB data；The surface of the targeted acquisition target of depth data characterization acquisition component with adopt
Collect the distance between component.
Here, it after the terminal can acquire a frame three dimensional video data, is just sent to the MEC server.Wherein,
When image to be collected is face, the frame three dimensional video data can correspond to a position of face, such as nose
Or mouth etc..
The terminal can acquire the three dimensional video data from the acquisition component at least capableing of sampling depth information；It is described
Acquisition component can establish communication link at least one terminal so that counterpart terminal obtains the three dimensional video data.
As an implementation, the terminal can acquire 3 D video number by the acquisition component independently of terminal
According to, then communication link established by the communication component in acquisition component and terminal, so that terminal obtains the three of acquisition component acquisition
Tie up video data.Wherein, the acquisition component can specifically be realized by least one of: depth camera, binocular camera,

Step 202: from the three dimensional video data, obtaining two-dimensional video data；Based on the terminal handshake phase
The model of foundation judges whether the two-dimensional video data obtained is accurate.
In view of the scene of terminal acquisition three dimensional video data may be low-light scene, due to the depth in three dimensional video data
Degree is not according to being too sensitive, and the precision of two-dimensional video data and light strong correlation to light, if two-dimensional video data is inaccurate,
It will cause the threedimensional model inaccuracy of MEC server foundation, i.e. the effect of building profile is fine, and fills the effect of color lump very
Difference.Therefore, MEC server needs to judge whether received two-dimensional video data is accurate, to guarantee to establish accurate threedimensional model.
In one embodiment, described based on the model established with the terminal handshake phase, judge the two-dimensional video obtained
Whether data are accurate, comprising: in the handshake phase with the terminal, determine the current scene of the terminal；From default scene with
In the corresponding relationship of model, the model of the corresponding current scene is searched；Based on the model found, accurately two dimension view is determined
Frequency is according to corresponding value range；Judge whether the corresponding numerical value of two-dimensional video data of acquisition belongs to the value range；When
Determine that the two-dimensional video data of determining acquisition is accurate when belonging to the value range；Otherwise, it determines the two-dimensional video data of acquisition
Inaccuracy.
Wherein, when two-dimensional video data is RGB data, it can be determined that whether the corresponding brightness value of RGB data belongs to institute
Value range is stated, also may determine that whether the corresponding color-values of RGB data belong to the value range.
As an implementation, the corresponding relationship of scene and model can be pre-established, wherein it is based on model, it can
Determine the value range of the accurate two-dimensional video data under low-light scene or strong laser field scape.
Assuming that the MEC server in the handshake phase with terminal, determines that the current scene of the terminal is dim light field
Scape, and from the corresponding relationship for pre-establishing scene and model, the corresponding model of low-light scene is searched, it is true based on determining model
Make the value range of accurate two-dimensional video data, it is assumed that be (100,2000)；The two-dimensional video data of judgement acquisition is corresponding
Brightness value or color-values whether belong to the value range；When determining that the two-dimensional video data in three dimensional video data is corresponding
When brightness value or color-values belong to the value range, determine that the two-dimensional video data obtained is accurate；Otherwise, it determines obtain two
Tie up video data inaccuracy.
As another embodiment, under low-light scene, it is being also based on environment light of the terminal under low-light scene
Brightness, establish the corresponding relationship of environmental light brightness and model, wherein be based on model, be capable of determining that varying environment light
The value range of accurate two-dimensional video data under degree.
As an example it is assumed that the current scene of terminal is low-light scene, the brightness of environment light is level1, determining scene
Model is model 1, and the value range of accurate two-dimensional video data is capable of determining that based on model 1, it is assumed that is (100,1500)；
The brightness of environment light is level2, and determining model is model 2, and model 2 is capable of determining that taking for accurate two-dimensional video data
It is worth range, it is assumed that be (100,1800).
The MEC server is if it is determined that the two-dimensional video data in the three dimensional video data of present frame is accurate, then to institute
It states terminal and sends confirmation response message；The terminal that the confirmation response message is used to indicate continues to acquire next frame 3 D video
Data.
Step 203: when determining the two-dimensional video data inaccuracy obtained, sending open command to the terminal；It is described
Open command is used to indicate terminal and opens the exposure compensating function of default closing.
When the corresponding rgb value of two-dimensional video data in the three dimensional video data for determining present frame does not fall within described first
When the value range of the corresponding rgb value of model, determine that the terminal is in low-light scene and acquires the two-dimensional video of inaccuracy
Data, therefore, MEC server can open exposure compensating function with instruction terminal, to resurvey three dimensional video data.
Assuming that the MEC server is it is confirmed that two-dimensional video data inaccuracy in nth frame three dimensional video data, then institute
It states after terminal receives the open instruction, needs to adopt the N frame three dimensional video data for having been issued to the MEC server again
Collection.
As an implementation, after terminal opens exposure compensating function, after resurveying N frame three dimensional video data,
And the N frame three dimensional video data resurveyed is successively sent to the MEC server；The MEC server receives the terminal
After the frame three dimensional video data resurveyed, judge whether the two-dimensional video data in the three dimensional video data of present frame is quasi-
Really；When the two-dimensional video data for determining present frame is accurate, indicate that the terminal continues to acquire next frame three dimensional video data；When
When determining the two-dimensional video data inaccuracy of present frame, after indicating the terminal adjustment exposure value, resurvey again.
As another embodiment, after terminal opens exposure compensating function, N frame three dimensional video data is resurveyed
Afterwards, and the N frame three dimensional video data resurveyed is successively sent to the MEC server；The MEC server receives the end
After holding the N frame three dimensional video data resurveyed, only judge whether the two-dimensional video data in nth frame three dimensional video data is quasi-
Really, when determining that the two-dimensional video data in the nth frame three dimensional video data that resurveys is accurate, it can use and resurvey
The two-dimensional video data of two-dimensional video data replacement inaccuracy in nth frame three dimensional video data, and resurveyed described in discarding
Residue frame three dimensional video data.Wherein, N is the positive integer greater than 1.
In one embodiment, the method also includes: when determine obtain two-dimensional video data it is accurate when, utilize the end
The three dimensional video data for holding acquisition, establishes threedimensional model.
The MEC server can use accurate two-dimensional video data and depth data, and combine preset algorithm, build
Vertical threedimensional model.The preset algorithm includes but is not limited to that three-dimensional point cloud is rebuild, three-dimensional model gridding segments, three-dimensional model gridding
Simplified, binocular vision reconstruction etc..

For, the accurate two-dimensional video data such as RGB data that can be acquired based on terminal carries out recognition of face；Based on depth data,
The human face region of identification is split, to be partitioned into the corresponding human face data of foreground part；Using the depth data, obtain
Three dimensional point cloud；To the three dimensional point cloud and human face data, point cloud matching, Data Integration are carried out, three-dimensional face is obtained
Model.
During establishing threedimensional model, depth data is for constructing profile.Due to the depth in three dimensional video data
Data are not depth data that is too sensitive, thus being acquired under low-light scene using the terminal to light, can still construct effect
The preferable profile of fruit.
During establishing threedimensional model, two-dimensional video data is for filling color lump.Due in three dimensional video data
Two-dimensional video data and light strong correlation, thus the two-dimensional video data acquired under low-light scene using the terminal, may
The threedimensional model inaccuracy that will cause foundation, that is, fill the poor effect of color lump.Obviously, the three-dimensional of two-dimensional video data and foundation
The accuracy of model has very big association.Therefore, MEC server needs to judge the two-dimensional video number in received three dimensional video data
According to whether accurately, to guarantee to establish accurate threedimensional model.
When terminal, which is in, acquires three dimensional video data under low-light scene, since MEC server can pass through instruction terminal
Exposure compensating is opened to guarantee that received two-dimensional video data is accurate, thus MEC server can be based on accurately two dimension
Video data and depth data establish accurate threedimensional model, i.e., the effect for not only constructing profile is fine, but also fill color lump
Effect it is also fine.
, can be in the case where the two-dimensional video data of acquisition be inaccurate using the technical solution of the embodiment of the present invention, MEC
Server sends open command to terminal, is opened the exposure compensating function of default closing with instruction terminal, and adopt again
Collect three dimensional video data, to guarantee that MEC server receives accurate two-dimensional video data, in this way, the MEC server just can
It is enough modeled using accurate two-dimensional video data and depth data, to improve the accuracy of modeling.

The terminal can acquire the three dimensional video data from the acquisition component at least capableing of sampling depth information；It is described
Acquisition component can establish communication link at least one terminal so that counterpart terminal obtains the three dimensional video data.
As an implementation, the terminal can acquire 3 D video number by the acquisition component independently of terminal
According to, then communication link established by the communication component in acquisition component and terminal, so that terminal obtains the three of acquisition component acquisition
Tie up video data.Wherein, the acquisition component can specifically be realized by least one of: depth camera, binocular camera,
3D structure light camera module, TOF camera module.
As another embodiment, terminal itself has the acquisition function of three dimensional video data, it will be understood that terminal is set
It is equipped with the acquisition component at least capableing of sampling depth information, such as is provided with at least one lower component: depth camera, binocular
Camera, 3D structure light camera module, TOF camera module, to acquire three dimensional video data.
Step 302: the three dimensional video data of acquisition is sent to MEC server.
Here, the terminal can acquire a frame three dimensional video data, and send frame three-dimensional view to the MEC server
Frequency evidence.Wherein, when image to be collected is face, the frame three dimensional video data can correspond to a portion of face
Position, such as nose or mouth etc..
Specifically, when the terminal sends the three dimensional video data of acquisition to MEC server, interval can be sent first
Interior transmission depth data；It is sent second and sends two-dimensional video data in interval.
Step 303: receiving the open command that the MEC server is sent；The open command is used to indicate default pass
The exposure compensating function of closing is opened；The open command is responded, the exposure compensating function of default closing is opened.
If the MEC server determines the inaccuracy of the two-dimensional video data in the three dimensional video data of present frame, to
The terminal sends open command, opens exposure compensating function with instruction terminal, and resurveys and have been issued to the MEC service
Whole three dimensional video datas of device.
If the MEC server determines that the two-dimensional video data in the three dimensional video data of present frame is accurate, to institute
It states terminal and sends confirmation response message；The terminal that the confirmation response message is used to indicate continues to acquire next frame 3 D video
Data.

If exposure value be adjusted again, continue to acquire next frame three-dimensional view until receiving the instruction that the MEC server is sent
Until the confirmation response message of frequency evidence.
During the MEC server establishes threedimensional model based on three dimensional video data, depth data is for constructing
Profile, since the depth data in three dimensional video data is not too sensitive to light, thus using the terminal in low-light scene
The depth data of lower acquisition can still construct the preferable profile of effect.
During the MEC server establishes threedimensional model based on three dimensional video data, two-dimensional video data is used for
Color lump is filled, due to the two-dimensional video data and light strong correlation in three dimensional video data, thus using the terminal in dim light
The two-dimensional video data acquired under scene is likely to result in the threedimensional model inaccuracy of foundation, that is, fills the poor effect of color lump.
Obviously, two-dimensional video data and the accuracy of the threedimensional model of foundation have very big association.Therefore, when MEC server judges to receive
Three dimensional video data in two-dimensional video data inaccuracy when, the three dimensional video data that is acquired under low-light scene of characterization terminal
It is middle occur inaccuracy two-dimensional video data, thus the terminal need to open exposure compensating after resurvey, to guarantee to send out
