Detailed Description

Before the technical solution of the embodiment of the present invention is explained in detail, a system architecture to which the data processing method of the embodiment of the present invention is applied is first briefly explained. The data processing method of the embodiment of the invention is applied to related services of three-dimensional video data, such as services for sharing three-dimensional video data, live broadcast services based on three-dimensional video data and the like. In this case, since the data amount of the three-dimensional video data is large, the depth data and the two-dimensional video data transmitted respectively need high technical support in the data transmission process, and thus the mobile communication network is required to have a high data transmission rate and a stable data transmission environment.

FIG. 1 is a schematic diagram of a system architecture for applying a data processing method according to an embodiment of the present invention; as shown in fig. 1, the system may include a terminal, a base station, an MEC server, a service processing server, a core network, the Internet (Internet), and the like; and a high-speed channel is established between the MEC server and the service processing server through a core network to realize data synchronization.

Taking an application scenario of interaction between two terminals shown in fig. 1 as an example, an MEC server a is an MEC server deployed near a terminal a (a sending end), and a core network a is a core network in an area where the terminal a is located; correspondingly, the MEC server B is an MEC server deployed near the terminal B (receiving end), and the core network B is a core network of an area where the terminal B is located; the MEC server A and the MEC server B can establish a high-speed channel with the service processing server through the core network A and the core network B respectively to realize data synchronization.

After three-dimensional video data sent by a terminal A are transmitted to an MEC server A, the MEC server A synchronizes the data to a service processing server through a core network A; and then, the MEC server B acquires the three-dimensional video data sent by the terminal A from the service processing server and sends the three-dimensional video data to the terminal B for presentation.

Here, if the terminal B and the terminal a realize transmission through the same MEC server, the terminal B and the terminal a directly realize transmission of three-dimensional video data through one MEC server at this time without participation of a service processing server, and this mode is called a local backhaul mode. Specifically, suppose that the terminal B and the terminal a realize transmission of three-dimensional video data through the MEC server a, and after the three-dimensional video data sent by the terminal a is transmitted to the MEC server a, the MEC server a sends the three-dimensional video data to the terminal B for presentation.

Here, the terminal may select an evolved node b (eNB) accessing the 4G network or a next generation evolved node b (gNB) accessing the 5G network based on a network situation, or a configuration situation of the terminal itself, or an algorithm of the self-configuration, so that the eNB is connected with the MEC server through a Long Term Evolution (LTE) access network, and the gNB is connected with the MEC server through a next generation access network (NG-RAN).

Here, the MEC server is deployed on the network edge side near the terminal or the data source, that is, near the terminal or near the data source, not only in a logical location but also in a geographical location. Unlike the existing mobile communication network in which the main service processing servers are deployed in several large cities, the MEC server can be deployed in a plurality of cities. For example, in an office building, there are many users, and a MEC server may be deployed near the office building.

The MEC server serves as an edge computing gateway with the core capabilities of network convergence, computing, storage and application, and provides platform support comprising an equipment domain, a network domain, a data domain and an application domain for edge computing. The intelligent connection and data processing system is connected with various intelligent devices and sensors, provides intelligent connection and data processing services nearby, enables different types of applications and data to be processed in the MEC server, achieves key intelligent services such as real-time service, intelligent service, data aggregation and interoperation, safety and privacy protection and the like, and effectively improves intelligent decision efficiency of the service.

The embodiment of the invention provides a data processing method, which is applied to a terminal, wherein the terminal can be a mobile terminal such as a mobile phone, a tablet personal computer and the like, and can also be a computer and other types of terminals. FIG. 2 is a first flowchart illustrating a data processing method according to an embodiment of the present invention; as shown in fig. 2, the method includes:

step 101: three-dimensional video data is obtained.

Step 102: and when the condition that the three-dimensional video data meet the preset condition is detected, storing the three-dimensional video data, processing the three-dimensional video data according to a preset rule, and sending the processed three-dimensional video data to a mobile edge computing MEC server.

In this embodiment, as an implementation manner, the obtaining three-dimensional video data includes: the terminal obtains three-dimensional video data from a collection assembly capable of collecting at least depth data; the acquisition component can establish a communication link with at least one terminal so that the corresponding terminal can obtain the three-dimensional video data.

Specifically, in this embodiment, since the acquisition component capable of acquiring the depth data is relatively expensive, the terminal does not have the function of acquiring the three-dimensional video data, but acquires the three-dimensional video data through the acquisition component independent of the terminal, and then establishes a communication link through the acquisition component and the communication component in the terminal, so that the terminal acquires the three-dimensional video data acquired by the acquisition component. The acquisition assembly can be specifically realized by at least one of the following components: the camera comprises a depth camera, a binocular camera, a 3D structured light camera module and a Time Of Flight (TOF) camera module.

Here, the acquisition component can establish a communication link with at least one terminal to transmit acquired three-dimensional video data to the at least one terminal, so that the corresponding terminal can acquire the three-dimensional video data, and thus, the three-dimensional video data acquired by one acquisition component can be shared with at least one terminal, thereby realizing the sharing of the acquisition component.

As another embodiment, the terminal has a function of acquiring three-dimensional video data, and it can be understood that the terminal is provided with an acquisition component capable of acquiring at least depth data, for example, at least one of the following components: degree of depth camera, binocular camera, 3D structured light module of making a video recording, TOF module of making a video recording to gather three-dimensional video data.

The obtained three-dimensional video data comprises two-dimensional video data and depth data; the two-dimensional video data is used for representing a planar image, and can be RGB data for example; the depth data characterizes a distance between a surface of an acquisition object for which the acquisition assembly is directed and the acquisition assembly.

In this embodiment, the detecting that the predetermined condition is satisfied includes: detecting transmission quality information of a communication channel between the MEC server and the MEC server, and determining that a preset condition is met when the transmission quality information does not meet a preset transmission standard.

Here, the transmission quality information includes a transmission rate and/or a packet loss rate; when the transmission rate is lower than a first preset threshold value, the transmission quality information can be shown to be not up to a preset transmission standard; and/or, when the packet loss rate is higher than a second preset threshold, it may also be indicated that the transmission quality information does not reach the preset transmission standard.

The embodiment is suitable for an application scenario where the quality of a communication channel between a terminal and an MEC server is poor, that is, a scenario where the transmission rate and/or the transmission stability of the communication channel do not meet a preset condition, for example, the transmission rate of the communication channel is lower than a first preset threshold, and the packet loss rate of data transmission is higher than a second preset threshold. Under the low-speed and/or high-delay scene, the terminal transmits the processed three-dimensional video data after processing the three-dimensional video data on one hand, and locally stores the three-dimensional video data on the other hand, so that errors occur in the transmission process of the three-dimensional video data, and the stored three-dimensional video data can be retransmitted.

As an embodiment, the processing the three-dimensional video data according to a preset rule and sending the processed three-dimensional video data to a mobile edge computing MEC server includes: segmenting the three-dimensional video data according to a preset rule to obtain a plurality of subdata, and sending the plurality of subdata to the MEC server; or compressing the three-dimensional video data according to a preset rule, and sending the compressed three-dimensional video data to an MEC server.

In this embodiment, because the transmission quality of the communication channel is not good (not meeting the preset transmission standard), before the three-dimensional video data to be transmitted is sent, the three-dimensional video data is processed to reduce the amount of transmitted data. As an embodiment, the three-dimensional video data may be segmented to obtain a plurality of sub-data; one subdata is transmitted during each transmission, so that the transmission quality of the current communication channel can be met, and the successful transmission of data is ensured by reducing the data transmission quantity. Here, as an example, the division of the three-dimensional video data may be division by areas, that is, each sub data corresponds to two-dimensional video data and depth data of one area. As another embodiment, the three-dimensional video data may be compressed according to a preset compression algorithm, so as to reduce the data volume of the three-dimensional video data.

In an embodiment, as shown in fig. 3, the method further comprises:

step 103 a: receiving first indication information from the MEC server; the first indication information is used for indicating the terminal to continue to transmit other three-dimensional video data; and obtaining other three-dimensional video data based on the first indication information, and sending the other three-dimensional video data to the MEC server.

In this embodiment, if the MEC server successfully builds the model based on the first data, that is, successfully builds the model, the MEC server sends first indication information to the terminal, where the first indication information indicates that the previously transmitted three-dimensional video data is successfully built, and may continue to acquire and transmit other three-dimensional video data.

In an embodiment, as shown in fig. 3, the method further comprises:

step 103 b: receiving second indication information from the MEC server; the second indication information is used for indicating the terminal to resend the three-dimensional video data; and retransmitting the three-dimensional video data based on the second indication information.

In this embodiment, if the MEC server fails to perform modeling based on the three-dimensional video data, second indication information is sent to the terminal, where the second indication information indicates that the previously transmitted three-dimensional video data cannot be successfully modeled and needs to be retransmitted for the stored three-dimensional video data.

In practical application, the amount of stored data can be determined based on the storage capacity of the terminal; it is understood that, upon receiving the first indication information of the MEC server, whether to delete the stored three-dimensional video data may be decided based on the storage capability of the terminal. As an embodiment, the stored three-dimensional video data may be deleted after receiving the first indication information. As another embodiment, the remaining storage space of the terminal may be detected; and if the residual storage space is smaller than the preset threshold value, deleting the stored three-dimensional video data according to the sequence of the storage time of the three-dimensional video data.

By adopting the technical scheme of the embodiment of the invention, the server can be matched with the preset model based on the obtained three-dimensional video data of one frame through the integral model of the plurality of target objects preset in the server, and the model of the target object can be quickly established based on the matched model, so that the modeling time is greatly shortened; on the other hand, because the model is preset in the server, the requirement of technical support required in the data transmission process is reduced, namely, a faster data transmission rate and a stable data transmission environment are not required, and the method is suitable for various communication scenes; in addition, because the model is preset in the server, the modeling can be carried out without transmitting all three-dimensional video data acquired by the terminal, and the data volume needing to be transmitted is reduced to a certain extent. In addition, the present embodiment stores the three-dimensional video data sent out by the terminal, and is suitable for scenes satisfying a predetermined condition (for example, poor transmission quality).

The embodiment of the invention also provides a data processing method, which is applied to a server, wherein the server is specifically the MEC server shown in FIG. 1. FIG. 4 is a third flowchart illustrating a data processing method according to an embodiment of the present invention; as shown in fig. 4, the method includes:

step 201: receiving three-dimensional video data from a terminal, and establishing an initial model based on the three-dimensional video data.

Step 202: matching the initial model with models in a preset model set; the preset model set comprises integral models of a plurality of target objects.

Step 203: and sending indication information to the terminal based on the matching result.

In this embodiment, as an implementation manner, the received three-dimensional video data includes two-dimensional video data and depth data; as another embodiment, only depth data may be included in the received three-dimensional video data. The server performs modeling based on the depth data in the received three-dimensional video data to obtain an initial model.

In this embodiment, the server sets a model set in advance, where the model set includes an entire model of a plurality of target objects. The target object may be a real person, a virtual person, a real animal, a virtual animal, and the like, and the category of the target object is not limited in this embodiment. In practical applications, the model set may include a plurality of sub-model sets, and each sub-model set may be for a category of target objects. For example, a corresponding sub-model set is preset for the real person; for a certain kind of real animals, such as dogs, a corresponding set of submodels may be preset, and so on.

In one embodiment, as shown in fig. 5, the method further comprises:

step 204: obtaining a plurality of sample data; the plurality of sample data are global data corresponding to different target objects and/or local data corresponding to different parts of the target objects.

Step 205: establishing an integral model of the target object based on the plurality of sample data; or, local models of different parts of the target object are established based on the plurality of sample data, and an overall model of different target objects is generated based on the local models of different parts of different target objects.

In this embodiment, the server establishes an overall model according to the obtained multiple sample data. As a first embodiment, the obtained sample data is whole data corresponding to the target object. For example, if the target object is a real person, the sample data is the entire data of the real person. As another embodiment, the obtained sample data is local data corresponding to different parts of the target object. For example, the target object is a real person which may include a head region, a trunk region (the trunk region may also be specifically divided into a shoulder region, a chest region, a waist region, and the like), and an extremity region (the extremity region may also be specifically divided into an arm region, a hand region, a leg region, a foot region, and the like), and the like, the sample data may be local regions for the above-described different parts of the real person.

It should be noted that, a plurality of sample data of the present embodiment correspond to different target objects, and even correspond to different parts of different target objects; it can be understood that the overall model is established for different target objects in the present embodiment.

In one embodiment, when the sample data is whole data corresponding to the target object, a whole model of the corresponding target object is established based on the whole data.

As another embodiment, when the sample data is local data corresponding to different parts of the target object, a corresponding local model of the target object is established based on the local data; further, the permutation and combination can be performed based on the local models of different parts of different target objects, such as the obtained local model a1 and local model a2 of the target object A; obtaining the local model B1 and the local model B2 of the target object B, on one hand, the overall model of the target object a can be established based on the local model a1 and the local model a2, and the overall model of the target object B can be established based on the local model B1 and the local model B2, on the other hand, one overall model can be established based on the local model a1 and the local model B2, and the other overall model can be established based on the local model B1 and the local model a 2. The present embodiment can obtain a larger number of overall models of the target object based on the local model, thereby facilitating model matching.

In this embodiment, the sample data may include only depth data; or may also include depth data and two-dimensional video data. Any data that can be modeled in three dimensions is within the scope of the embodiments of the present invention.

It is to be understood that step 204 and step 205 are performed before step 202, i.e. before the initial model is matched with the models in the preset model set, the building of the overall model in the model set is performed.

In this embodiment, the server matches the initial model with a model in a preset model set.

As one embodiment, the server matches the initial model to the overall model in a pre-set of models. The embodiment is applicable to a scene in which the received three-dimensional video data is whole data corresponding to the target object, that is, as an example, the terminal transmits all the acquired three-dimensional video data corresponding to the whole target object to the server, so that the three-dimensional video data received by the server is the three-dimensional video data corresponding to the whole target object, and an initial model established by the server based on the three-dimensional video data is an initial model corresponding to the whole target object.

In another embodiment, the server matches the initial model with the local models that make up the global model in a pre-set of models. The present embodiment is applicable to a scene in which the received three-dimensional video data is local data of a part corresponding to the target object, that is, as an example, the terminal transmits the acquired three-dimensional video data of each part corresponding to the target object to the server, and the server needs to perform modeling processing on the received three-dimensional video data of each part, that is, the initial model obtained here is an initial model of each part corresponding to the target object.

In this embodiment, the matching the initial model with the models in the preset model set includes: and extracting the characteristic parameters of the initial model, and matching the characteristic parameters of the initial model with the characteristic parameters of the models in the model set to obtain the matching rate.

Specifically, in the process of matching the initial model with the models in the preset model set, regardless of the initial model corresponding to the whole target object or the initial models corresponding to the parts of the target object, as an embodiment, the characteristic parameters of the initial model are extracted, and the extracted characteristic parameters are matched with the characteristic parameters of the models in the model set; if the matching rate of the extracted characteristic parameters and the characteristic parameters of a certain model exceeds a preset threshold value, the matching success can be indicated; correspondingly, if the matching rate of the extracted characteristic parameters and the characteristic parameters of any model in the model set does not exceed the preset threshold, the matching failure can be indicated. The characteristic parameters may be parameters characterizing feature points of the contour and/or key points of the bone.

In an embodiment, as shown in fig. 6, the method further comprises:

step 203 a: and when the matching result is that the initial model is matched with a model in a preset model set, sending first indication information to the terminal, wherein the first indication information is used for indicating the terminal to continuously transmit other three-dimensional video data.
