Detailed ways

Before the technical solutions of the embodiments of the present invention are described in detail, the system architecture to which the data processing methods of the embodiments of the present invention are applied is briefly described first. The data processing method of the embodiment of the present invention is applied to a service related to 3D video data, such as a service of sharing 3D video data, or a live broadcast service based on 3D video data, and the like. In this case, due to the large amount of 3D video data, the depth data and 2D video data transmitted respectively require high technical support in the data transmission process, so the mobile communication network needs to have a faster data transmission rate , and a more stable data transmission environment.

FIG. 1 is a schematic diagram of a system architecture of an application of 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, and the Internet (Internet), etc.; the MEC server and the service A high-speed channel is established between the processing servers through the core network to achieve data synchronization.

Taking the application scenario of the interaction between two terminals shown in Figure 1 as an example, the MEC server A is the MEC server deployed near the terminal A (sender), and the core network A is the core network in the area where the terminal A is located; correspondingly, the MEC server B is the MEC server deployed near the terminal B (receiving end), and the core network B is the core network in the area where the terminal B is located; Establish high-speed channels for data synchronization.

Wherein, after the 3D video data sent by terminal A is transmitted to MEC server A, MEC server A synchronizes the data to the service processing server through core network A; and then MEC server B obtains the 3D video data sent by terminal A from the service processing server, and sent to terminal B for presentation.

Here, if terminal B and terminal A realize transmission through the same MEC server, then terminal B and terminal A directly realize the transmission of 3D video data through an MEC server without the participation of the service processing server. This method is called local return method. Specifically, it is assumed that terminal B and terminal A transmit 3D video data through MEC server A. After the 3D video data sent by terminal A is transmitted to MEC server A, MEC server A sends the 3D video data to terminal B for presentation.

Here, the terminal may select an evolved base station (eNB) to access the 4G network, or a next-generation evolved base station (gNB) to access the 5G network based on the network conditions, or the configuration of the terminal itself, or an algorithm configured by itself, so that the The eNB is connected to the MEC server through a Long Term Evolution (Long Term Evolution, LTE) access network, so that the gNB is connected to the MEC server through a Next Generation Access Network (NG-RAN).

Here, the MEC server is deployed on the edge of the network close to the terminal or data source. The so-called close to the terminal or close to the data source is not only logically located, but also geographically close to the terminal or close to the data source. Different from the existing mobile communication network where the main service processing servers are deployed in several large cities, multiple MEC servers can be deployed in one city. For example, in an office building with many users, an MEC server can be deployed near the office building.

Among them, the MEC server, as an edge computing gateway with core capabilities of integrating network, computing, storage and application, provides platform support for edge computing including device domain, network domain, data domain and application domain. It connects various smart devices and sensors, provides smart connection and data processing services nearby, and allows different types of applications and data to be processed in the MEC server to achieve real-time business, business intelligence, data aggregation and interoperability, security and privacy protection, etc. Key intelligent services can effectively improve the efficiency of intelligent business decision-making.

An embodiment of the present invention provides a data processing method, which is applied to a terminal, and the terminal may be a mobile terminal such as a mobile phone and a tablet computer, or a terminal of a type such as a computer. FIG. 2 is a schematic flowchart 1 of a data processing method according to an embodiment of the present invention; as shown in FIG. 2 , the method includes:

Step 101: Obtain three-dimensional video data.

Step 102 : when it is detected that a predetermined condition is met, store the 3D video data, process the 3D video data according to preset rules, and send the processed 3D video data to the mobile edge computing MEC server.

In this embodiment, as an implementation manner, the obtaining of 3D video data includes: the terminal obtains 3D video data from a collection component capable of collecting at least depth data; the collection component can establish a communication link with at least one terminal so that the corresponding terminal obtains the three-dimensional video data.

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

Here, the collection component can establish a communication link with at least one terminal to transmit the collected 3D video data to the at least one terminal, so that the corresponding terminal can obtain the 3D video data, so that the 3D video data collected by one collection component can be shared. To at least one terminal, so as to realize the sharing of acquisition components.

As another embodiment, the terminal itself has the function of collecting 3D video data. It can be understood that the terminal is provided with a collection component capable of collecting depth data at least, for example, at least one of the following components is provided: a depth camera, a binocular camera, a 3D structure Optical camera module and TOF camera module to collect 3D video data.

Wherein, the obtained three-dimensional video data includes two-dimensional video data and depth data; the two-dimensional video data is used to represent a plane image, such as RGB data; distance between.

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

Here, the transmission quality information includes the transmission rate and/or the packet loss rate; when the transmission rate is lower than the first preset threshold, it may indicate that the transmission quality information does not meet the preset transmission standard; and/or, when the packet loss When the rate is higher than the second preset threshold, it may also indicate that the transmission quality information does not meet the preset transmission standard.

This embodiment is applicable to the application scenario where the quality of the communication channel between the terminal and the MEC server is poor, that is, the scenario where the transmission rate and/or transmission stability of the communication channel do not meet the preset conditions, for example, the transmission rate of the communication channel is lower than The first preset threshold, the packet loss rate of data transmission is higher than the second preset threshold. In such a low-speed and/or high-latency scenario, the terminal processes the 3D video data and transmits the processed 3D video data on the one hand, and stores the 3D video data locally on the other hand, so that the 3D video data can appear during the transmission of the 3D video data. error, the stored 3D video data can be retransmitted.

As an embodiment, the processing the 3D video data according to preset rules and sending the processed 3D video data to the mobile edge computing MEC server includes: processing the 3D video data according to preset rules. Segmentation processing, obtaining multiple sub-data, and sending the multiple sub-data to the MEC server; or, performing compression processing on the 3D video data according to a preset rule, and sending the compressed 3D video data to the MEC server.

In this embodiment, since the transmission quality of the communication channel is not good (the preset transmission standard is not met), before sending the 3D video data to be transmitted, the 3D video data is processed to reduce the amount of transmitted data. As an embodiment, the 3D video data can be divided and processed to obtain multiple sub-data; one sub-data is transmitted in each transmission, so as to satisfy the transmission quality of the current communication channel, and the data transmission volume can be reduced to ensure the data of successful transmission. Here, as an example, the segmentation of the three-dimensional video data may be performed by regions, that is, each sub-data corresponds to two-dimensional video data and depth data of one region. As another implementation manner, the 3D video data may also be compressed according to a preset compression algorithm, thereby reducing the data amount of the 3D video data.

In one embodiment, as shown in FIG. 3 , the method further includes:

Step 103a: Receive first indication information from the MEC server; the first indication information is used to instruct the terminal to continue to transmit other 3D video data; obtain other 3D video data based on the first indication information, and send it to the The MEC server sends the other three-dimensional video data.

In this embodiment, if the MEC server succeeds in modeling based on the first data, that is, the model is successfully established, the MEC server sends first indication information to the terminal. The first indication information indicates that the previously transmitted 3D video data has been successfully modeled, and the collection can continue. And transmit other 3D video data.

In one embodiment, as shown in FIG. 3 , the method further includes:

Step 103b: Receive second indication information from the MEC server; the second indication information is used to instruct the terminal to resend the 3D video data; and based on the second indication information, resend the 3D video data.

In this embodiment, if the modeling based on the 3D video data is unsuccessful, the MEC server sends second indication information to the terminal. The second indication information indicates that the previously transmitted 3D video data cannot be successfully modeled, and the stored 3D video data needs to be retransmitted. video data.

In practical applications, the amount of stored data can be determined based on the storage capability of the terminal; it can be understood that after receiving the first indication information from the MEC server, it can be determined whether to delete the stored 3D video data based on the storage capability of the terminal. As an implementation manner, after receiving the first indication information, the stored 3D video data may be deleted. As another implementation manner, the remaining storage space of the terminal can be detected; if the remaining storage space is less than a preset threshold, the stored 3D video data can be deleted in the order of storage time of the 3D video data.

By adopting the technical solution of the embodiment of the present invention, through the overall models of multiple target objects preset in the server, on the one hand, the server can match the preset model based on one frame of 3D video data obtained, and can match the model based on the matching model. Quickly build the model of the target object, which greatly shortens the modeling time; on the other hand, because the model is preset in the server, the requirements for technical support in the data transmission process are reduced, that is, faster data transmission is not required. The speed and stable data transmission environment are suitable for various communication scenarios; in addition, because the model is preset in the server, it is also possible to model without transmitting all the 3D video data collected by the terminal, which also reduces the need for transmission to a certain extent. amount of data. In addition, this embodiment stores the 3D video data sent by the terminal, and is suitable for scenarios that meet predetermined conditions (eg, poor transmission quality).

An embodiment of the present invention further provides a data processing method, which is applied to a server, and the server is specifically the MEC server shown in FIG. 1 . FIG. 4 is a third schematic flowchart of a data processing method according to an embodiment of the present invention; as shown in FIG. 4 , the method includes:

Step 201: Receive 3D video data from a terminal, and establish an initial model based on the 3D video data.

Step 202 : Match the initial model with a model in a preset model set; the preset model set includes overall models of multiple target objects.

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

In this embodiment, as an implementation, the received three-dimensional video data includes two-dimensional video data and depth data; as another implementation, the received three-dimensional video data may also include only depth data. Then, the server performs modeling based on the depth data in the received 3D video data to obtain an initial model.

In this embodiment, the server presets a model set, and the model set includes the overall models of multiple target objects. Wherein, the target object may be a real person, a virtual person, a real animal, a virtual animal, etc., and the category of the target object is not limited in this embodiment. In practical applications, the model set may include multiple sub-model sets, and each sub-model set may target a type of target object. For example, a corresponding sub-model set may be preset for a real person; a corresponding sub-model set may be preset for a certain type of real animal, such as a dog, and so on.

In one embodiment, as shown in FIG. 5 , the method further includes:

Step 204: Obtain a plurality of sample data; the plurality of sample data are overall data corresponding to different target objects and/or local data corresponding to different parts of the target object.

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

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 overall data corresponding to the target object. For example, if the target object is a real person, the sample data is the overall data of the real person. As another implementation manner, the obtained sample data is local data corresponding to different parts of the target object. For example, the target object is a real person, and the real person may include a head area, a torso area (the torso area can also be specifically divided into a shoulder area, a chest area, a waist area, etc.) and a limb area (the limb area can also be specifically divided into arms area, hand area, leg area, foot area, etc.), etc.), the sample data may be local areas for the above-mentioned different parts of a real person.

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

As an implementation manner, when the sample data is overall data corresponding to the target object, an overall model of the corresponding target object is established based on the overall data.

As another implementation, when the sample data is local data corresponding to different parts of the target object, a local model of the corresponding target object is established based on the local data; further, the local models of different parts of the target object can be based on For example, the local model a1 and local model a2 of target object A are obtained; the local model b1 and local model b2 of target object B are obtained, on the one hand, the overall target object A can be established based on the local model a1 and local model a2. model, based on the local model b1 and the local model b2 to establish the overall model of the target object B, on the other hand, it can also establish an overall model based on the local model a1 and the local model b2, and establish another overall model based on the local model b1 and the local model a2. In this embodiment, a larger number of overall models of the target object can be obtained based on the local models, thereby facilitating model matching.

In this embodiment, the sample data may only include depth data; or may also include depth data and two-dimensional video data. Any data that can build a three-dimensional model falls within the protection scope of the embodiments of the present invention.

It can be understood that steps 204 and 205 are performed before step 202, that is, before the initial model is matched with the models in the preset model set, the establishment of the overall model in the model set is performed.

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

As an embodiment, the server matches the initial model with the overall model in the preset model set. This embodiment is applicable to a scenario where the received 3D video data is the overall data corresponding to the target object, that is, as an example, if the terminal transmits all the collected 3D video data corresponding to the entire target object to the server, the server receives The three-dimensional video data is the three-dimensional video data corresponding to the entirety of the target object, and the initial model established by the server based on the three-dimensional video data is the initial model corresponding to the entirety of the target object.

As another implementation manner, the server matches the initial model with the partial models constituting the overall model in the preset model set. This embodiment is applicable to a scene in which the received 3D video data is local data corresponding to the parts of the target object, that is, as an example, the terminal transmits the collected 3D video data corresponding to each part of the target object to the server respectively, then The server needs to separately model the received 3D video data corresponding to each part, that is, the initial model obtained here is the initial model corresponding to each part of the target object.

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

Specifically, whether it is an initial model corresponding to the entire target object or an initial model corresponding to each part of the target object, in the process of matching the initial model with the models in the preset model set, as an implementation manner , extract the characteristic parameters of the initial model, and match the extracted characteristic parameters with the characteristic parameters of each model in the model set; if the matching rate between the extracted characteristic parameters and the characteristic parameters of a certain model exceeds a preset threshold, It can indicate that the matching is successful; correspondingly, if the matching rate between the extracted feature parameter and the feature parameter of any model in the model set does not exceed the preset threshold, it can indicate that the matching fails. The feature parameters may specifically be parameters representing contour feature points and/or bone key points.

In one embodiment, as shown in FIG. 6 , the method further includes:

Step 203a: when the matching result is that the initial model matches the model in the preset model set, send first indication information to the terminal, where the first indication information is used to instruct the terminal to continue to transmit other 3D video data.

In this embodiment, if the MEC server determines that the initial model matches the model in the preset model set, that is, the model corresponding to the 3D video data is successfully established, the MEC server sends first indication information to the terminal, and the first indication information indicates that The previously transmitted 3D video data can be successfully modeled, and the next 3D video data can be transmitted.

In an embodiment of the present invention, when the matching result is that the initial model matches a model in a preset model set, a first model is generated based on the three-dimensional video data and the matched model.

In this embodiment, when the matching result is that the initial model matches the model in the preset model set, it indicates that the overall model of the corresponding target object has been stored in the server; however, the overall model often matches the 3D video data. The corresponding target objects are not completely consistent; then this embodiment adjusts and optimizes the matched model based on the three-dimensional video data (including the two-dimensional video data and the depth data). It can be understood that on the basis of the matched model, it is only necessary to do The first model corresponding to the target object can be obtained by corresponding adjustment; compared with the method of generating a model by referring to 3D video data, the embodiment of the present invention can greatly shorten the time-consuming of model establishment.

In an embodiment of the present invention, when the matching result is that the initial model matches a model in a preset model set, the method further includes: updating the matched model based on the three-dimensional video data.
