[0022] To make the objectives, features, and advantages of this invention more apparent and understandable, the technical solutions of the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described below are only some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0023] It should be understood that the terms "comprising" and other similar expressions in the specification, claims, and accompanying drawings of this invention are intended to cover a non-exclusive inclusion, such as a process, method, system, or apparatus that includes a series of steps or units and is not limited to the listed steps or units. Furthermore, "first" and "second" are used to distinguish different objects and are not intended to describe a specific order.

[0024] Understandably, traditional high-precision map creation (extraction) tools are industrial application software that require human-computer interaction during the creation process. The extraction of map elements is done manually and then created into digital data in the software, thus completing one step in the high-precision map creation process. In contrast, the automated high-precision map extraction tool is based on artificial intelligence algorithms to automatically identify map elements and then convert them into digital data, thus completing one step in the high-precision map creation process.

[0025] Please see Figure 1 The present invention provides a flowchart illustrating a configuration management method for a high-precision map automated extraction tool, comprising:

[0026] S101. Obtain the input production configuration information based on the pre-defined configuration page, and generate the corresponding configuration file or add the corresponding production record on the server according to the production configuration information.

[0027] The pre-configuration page is used by technicians to input production configuration information, which includes production server, batch, database name, original data path, intermediate data path, signboard, map elements, etc.

[0028] The pre-configured page is requested by the interface provided by the backend server through the request method in the Flask framework, and rendered by the render function of the Flask framework.

[0029] Enter the relevant information on the configuration page. The configuration page is requested by the add_config interface provided by the system backend service through the get method of flask.request, and the page is rendered to the browser by the render_template() function of the Flask framework.

[0030] Preferably, the system calls the backend server's API to request the submitted production configuration information, verifies and filters the production configuration information, and automatically extracts the element values ​​from the production configuration information. Alternatively, the system calls the `add_config` API of the backend service to request the submitted configuration information via the `flask.request` POST method, and then verifies and filters the configuration information.

[0031] Among these, the version number of the precision map automatic extraction tool, the production server, the station information, the database to be written, the original data path, the intermediate data path, the graphics card, and the extracted features must not be empty values.

[0032] The production configuration information includes corresponding user options for selecting whether to generate a configuration file or add production records to the current configuration, or both simultaneously. Specifically, the user is determined based on the options corresponding to the configuration file in the production configuration information: generate only the configuration file, add only production records to the database, or perform both configuration file generation and production record addition simultaneously.

[0033] The generated configuration file includes:

[0034] An XML file is created using the `createDocument` function from Python's `minidom` module. The production configuration information, based on the requirements of the high-precision map automatic extraction tool configuration file, is then written into the XML file using the `open` function. Specifically, the `getDOMImplementation().createDocument()` function from Python's `xml.dom.minidom` module creates an XML file and writes the configuration information according to the requirements of the automatic extraction tool configuration file into it.

[0035] S102. Override the production configuration file in the high-precision map automated extraction tool based on the generated configuration file;

[0036] The newly generated configuration file can directly overwrite the original production configuration file in the high-precision map automated extraction tool, and the map data extraction and production can be carried out through the overwritten automated extraction tool.

[0037] Overwrite the config.xml configuration file in the high-precision map automatic extraction tool, and the high-precision map automatic extraction tool can then start production.

[0038] S103. Extract key information from the configuration file, reorganize it into production records, and save it to the database;

[0039] The information in the configuration file is selectively extracted, and the log record information related to the production of high-precision maps is selected to obtain the production record.

[0040] Specifically, the form information is assembled, unnecessary information is removed from the form, and the MySQL database is connected using the connect() function in the pymysql module of Python. Production records are then inserted and stored in the database for later querying, backup, and export.

[0041] S104. View the production record information on the system page and export the production record information.

[0042] Specifically, production record information is retrieved from the database via the `get_pro_info` interface provided by the system backend server, and then rendered to the browser using the `render_template()` function of the Flask framework. Similarly, production results are retrieved from the database via the `get_result_info` interface provided by the system backend service, and then rendered to the browser using the `render_template()` function of the Flask framework.

[0043] The production record export includes:

[0044] The system calls the interface provided by the backend server to obtain the time period information to be exported, connects to the database through the connect function in the pymysql module, queries the log records to be exported, creates a table document through the Wordbook function in the xlwt module, creates the corresponding table, writes the log record data to the table file and saves it, and renders the table file path for download and use.

[0045] After selecting the time period to be exported, the system obtains the time period information by calling the export_pro_log interface of the system backend service. It then connects to the database using the connect() function in the pymysql module of Python, queries the log records or result data to be exported, creates an xls document using the Wordbook() function in the xlwt module of Python, creates a sheet using the add_sheet() function, writes the data to the xls file and saves it, and renders the file path using render_template() for download and use.

[0046] This embodiment reduces manual intervention, improves the configuration efficiency of automated extraction tools, and thus increases the efficiency of high-precision map production. Simultaneously, it facilitates the querying and tracing of map production records, simplifying the management of the production configuration process.

[0047] In another embodiment, such as Figure 2As shown, after the staff inputs the production configuration information on the client, they start the high-precision map automatic extraction tool. The backend management server can generate a configuration file and assemble the production record information based on the configuration information. The configuration file is sent to the high-precision map automatic extraction tool, overwriting the existing configuration file, and the generated records are sent to the MySQL database for storage. The MySQL database can provide production record query and export services for the client.

[0048] The high-precision map automatic extraction tool is used to extract features from the input field measurement and collection data, such as extracting road lane lines based on collected laser point clouds, video images, etc.

[0049] It should be understood that the sequence number of each step in the above embodiments does not imply the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of the present invention.

[0050] Figure 3 This invention provides a schematic diagram of a configuration management system for a high-precision map automated extraction tool, comprising:

[0051] Client 310 is used to input production configuration information through the pre-defined configuration page, view production record information on the system page, and export production record information;

[0052] The pre-configured page is requested by the interface provided by the backend server through the request method in the Flask framework, and rendered by the render function of the Flask framework.

[0053] The system service module 320 obtains the input production configuration information, generates the corresponding configuration file or adds the corresponding production record on the server based on the production configuration information, and extracts the key information in the configuration file to reorganize it into a production record.

[0054] Specifically, the system service module includes a generation unit and an extraction and recombination unit: the generation unit is used to generate corresponding configuration files or add corresponding production records on the server according to the production configuration information; the extraction and recombination unit is used to extract key information from the configuration files and recombine them into production records.

[0055] The process involves calling the backend server's interface to request the submitted production configuration information, verifying and filtering the production configuration information, and then automatically extracting the element values ​​from the production configuration information.

[0056] Among them, the options corresponding to the configuration file in the production configuration information are used to determine whether to generate only the configuration file, add only the production record to the database, or generate the configuration file and add the production record at the same time.

[0057] Specifically, an XML file is created using the createDocument function in Python's minidom module, and the production configuration information is written into the XML file according to the configuration file requirements of the high-precision map automatic extraction tool using the open function.

[0058] Database 330 is used to store production records;

[0059] Extraction tool 340 is used to overwrite the production configuration file in the high-precision map automated extraction tool based on the generated configuration file.

[0060] The process involves calling the interface provided by the system's backend server to obtain the time period information to be exported, connecting to the database through the connect function in the pymysql module, querying the log records to be exported, creating a table document through the Wordbook function in the xlwt module, creating the corresponding table, writing the log record data into the table file and saving it, and rendering the table file path for download and use.
