Benefits of technology

This patented technology helps analyze content without storing it permanently or requiring too much storage space for future use. It uses an identifier called title (title) instead of just one bit of data like its own identity number. By analyzing this identifier's value, we can determine which part needs more resources during processing time compared to older methods such as comparing attributes directly. Overall, these improvements improve efficiency and accuracy in identifying topics related to specific subjects within media files.

Problems solved by technology

This patented describes how each type of entity called a topic has its own unique identifier that helps it work with other entities like sensors and cameras. When these objects exchange data over networks they have their identifiers stored separately from any others' ones by defaulting to being used only once per day instead of continuously every time. Additionally, when this happens frequently, the process becomes very complex due to the large number of attributes associated with certain things such as people who may belong to another person or object within one group.

Embodiment 1

[0043] figure 1 It is a flowchart of a data processing method provided by Embodiment 1 of the present invention. This embodiment is applicable to the case of processing theme data. The method can be executed by a data processing device, and the device can be realized by software and / or hardware. see figure 1 , the data processing method provided in this embodiment includes:

[0044] S110. Receive a theme data access instruction including a target theme ID.

[0045] Specifically, before receiving the subject data access instruction including the target subject ID, it also includes:

[0046] Get the target topic ID;

[0047] Generate a data access instruction of the target subject according to the acquired target subject ID.

[0048] Wherein, the target topic ID refers to the topic ID of the topic to be processed. The topic ID can be any identifier smaller than the data volume of the topic's name string. Typically, it can be a fixed-length integer number, for example, th...

Embodiment 2

[0061] figure 2 It is a flowchart of a data processing method provided in Embodiment 2 of the present invention. This embodiment is an optional solution proposed on the basis of the foregoing embodiments. see figure 2 , the data processing method provided in this embodiment includes:

[0062] S210. Obtain the name string of each theme during the initialization process.

[0063] Because the name string of a topic usually consists of multiple module names for data communication of the topic, the name string of a topic is usually longer and takes up more storage space.

[0064] S220. Using a preset hashing algorithm, hash the name string of each topic into a fixed-length topic ID.

[0065] Wherein, the preset hash algorithm (also called a hash function) may be any algorithm for converting the subject name string into a subject ID with a small amount of data, which may be specifically set according to actual needs. The setting length of the topic ID can also be set accordin...

Embodiment 3

[0075] image 3 It is a schematic structural diagram of a data processing device provided in Embodiment 3 of the present invention. see image 3 , the data processing device provided in this embodiment includes: an instruction receiving module 10 and a data search module 20.

[0076] Wherein, the instruction receiving module 10 is used to receive the theme data access instruction including the target theme ID identity;

[0077] The data search module 20 is used to search for the data of the target theme by using the target theme ID as an index in the pre-built theme data index list, wherein the theme data index list uses the theme ID as the key and the data of the theme as the key value The index table of the subject ID is obtained by hashing the name string of the subject.

[0078] In the technical solution of the embodiment of the present invention, the topic name string is converted into a topic ID, because the topic ID occupies less memory than the topic name string, th...

Abstract

The embodiment of the invention discloses a data processing method, a device, an apparatus and a medium, which relate to the field of automatic driving. The method includes receiving a topic data access instruction including a target topic ID; in a pre-constructed subject data index list, data of a target subject being searched with the target subject ID as an index, wherein the subject data indexlist is an index table with the subject ID as a keyword and the data of the subject as a key value, and the subject ID being obtained by hashing a name string of the subject. The embodiment of the invention provides the data processing method, the device, the apparatus and the medium, which reduce the overhead of the subject name operation.
