Description

Technical Field

[0001] The present invention relates to the technical field of map data importing, in particular to an information processing system for map data importing. Background Art

[0002] Map data import is the process of introducing map-related data files or information into a map software or system for visualization, analysis or editing. This data can include geographic coordinates, road networks, terrain information, etc.

[0003] When map data is imported, the map data information needs to be processed. Therefore, an information processing system for importing map data is needed.

[0004] After processing and extracting map information data, current common information processing systems generally directly overwrite the original data, which can easily import abnormal data information and cause system map information anomalies. Summary of the invention

[0005] In view of the deficiencies of the prior art, the present invention provides an information processing system for importing map data, which solves the problems raised in the above-mentioned background technology.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solutions: an information processing system for map data import, including a data acquisition module, a data processing module, a data comparison module and a data storage module;

[0007] The data acquisition module is interactively connected to the input end of the data processing module, the data processing module is interactively connected to the input end of the data comparison module, and the data comparison module is interactively connected to the input end of the data storage module;

[0008] The data acquisition module is used for collecting and calibrating map information;

[0009] The data processing module is used to extract and process map information;

[0010] The data comparison module is used to compare and verify the processed map data with the original map data;

[0011] The data storage module is used to overwrite the original map data with the processed map data and save the original map data.

[0012] Optionally, the data acquisition module includes a data acquisition unit and a data calibration unit;

[0013] The data acquisition unit is used to obtain and import map data information through satellite images, aerial photos, geographic information system data, and geographic tags;

[0014] The data calibration unit is used to calibrate the data after data collection to verify whether the data is missing or erroneous. If data errors or missing occur, the data will be deleted and the data will be acquired again.

[0015] Optionally, the data processing module includes a data extraction unit and a data processing unit;

[0016] The data extraction unit is used to extract the map coordinate system, geographic name and coordinate system image from the acquired correct map data information data, and then classify the map coordinate system, geographic name and coordinate system image in the extracted data;

[0017] The data processing unit is used to divide and process the extracted data. The geographical name is marked as A and used as a data reference punctuation; the map coordinate system is marked as b and used as a data reference verification punctuation; the coordinate system image is cut according to 1m*1m, and the distribution of the cut image is divided according to the XY axis, and the map coordinate system is used as the origin. The image is marked according to the position of the cut image from the origin. The marking format is (X, Y), and the origin is marked as (0, 0). The extracted data is marked according to the Ab (X, Y) marking format;

[0018] Optionally, the data comparison module includes a first CPU and a second CPU;

[0019] The first CPU and the second CPU have the same function. The first CPU and the second CPU simultaneously retrieve map data marked in the Ab(X, Y) marking format and map data of the map data storage unit, and process them in the first CPU and the second CPU at the same time to find the map data in the Ab(X, Y) marking format under the same geographical name. When the same geographical name appears, the map data in the Ab(X, Y) marking format of the same map coordinate system is found in the map data in the Ab(X, Y) marking format of the same geographical name. When the same geographical name is not retrieved, the map data in the Ab(X, Y) marking format of the same map coordinate system is retrieved based on the map coordinate system. Then the first CPU inputs the processed data into the second CPU, compares the first CPU and the second CPU, and after the comparison is confirmed to be correct, generates a data overwrite instruction to transmit it to the map data storage unit.

[0020] Optionally, the data storage module includes a map data storage unit and a raw data storage unit;

[0021] The map data storage unit is used to receive the data overwriting instruction of the data comparison unit, extract the map data information to be overwritten and save it to the original data storage unit, and then use the newly generated Ab (X, Y) mark format map data information to correspondingly overwrite the original Ab (X, Y) mark format map data information;

[0022] The original data storage unit is used to save the overwritten original data information to facilitate subsequent manual retrieval, review and approval.

[0023] The present invention provides an information processing system for importing map data, which has the following beneficial effects:

[0024] The information processing system for importing map data uses a data processing module. The data processing unit in the data processing module can divide and process the data extracted by the data extraction unit. The geographical name is marked as A and used as a data comparison punctuation; the map coordinate system is marked as b, the coordinate system image is cut according to 1m*1m, and the image is marked in (X, Y) format. The extracted data is marked in Ab (X, Y) marking format. When covering map information data, data coverage can be performed more accurately, thereby improving the accuracy of map data import.

[0025] The information processing system for importing map data has a data comparison module, and the first CPU and the second CPU have the same function. The first CPU and the second CPU can process map information at the same time, and compare the processed information with the original map information at the same time, and then input the information compared by the first CPU into the second CPU, and then compare the comparison information in the first CPU and the second CPU. When the comparison information is the same, the map data information is overwritten to avoid abnormal situations when the map data information is overwritten. BRIEF DESCRIPTION OF THE DRAWINGS
