Problems solved by technology

In addition, there is another means of data inspection, which is offline program inspection, but the inspection results are not inherited. Records that have been confirmed as not requiring modification are still reported by each offline inspection, which will increase the amount of manual work.
[0004] In the process of realizing the present invention, it is found that there are at least the following problems in the prior art: the existing data correctness check method is usually an offline check, and is manually triggered, so the accuracy of the data check result will be affected due to human factors, Thus, wrong data may be output to the navigation electronic map

Embodiment Construction

[0058] In this embodiment, firstly, during the data entry process, the correctness of the intermediate result data in the data entry process is checked online, and the correct intermediate result data is allowed to be saved, thereby avoiding saving the wrong intermediate result data in the database middle. After the data input is completed, the correctness of the input result data is checked offline. By combining the above two checking methods, it can effectively prevent wrong result data from being entered into the database of the navigation electronic map.

[0059] In order to facilitate understanding, firstly, the drawing process of navigation electronic map is roughly divided into three major links, the specific links are as follows:

[0060] Step 1. Data collection process;

[0061] The above-mentioned data refers to the data used to draw the navigation electronic map, and the types of the data include: GPS track, voice, picture or mark, etc.

[0062] Step 2: Data entry...

Abstract

The invention provides a data checking method used for navigation electronic map production and a device thereof, belonging to the field of navigation technology. The method comprises the steps of: collecting the data used for drawing a navigation electronic map; inputting the collected data to the data base of the navigation electronic map and obtaining intermediate outcome data in the process of inputting; checking whether the outcome data input into the data base is correct on line according to preset data correctness checking rule during the implementation of of data input, if so, allowing the intermediate outcome data to be stored in the data base as outcome data; and after the step of data input is finished, checking whether the outcome data after the input is finished is correct, if so, converting the outcome data into the product data of the navigation electronic map. By the combination of the two correctness checking modes, the invention can effectively prevent wrong data from being input into the data base of the navigation electronic map, thus ensuring the correctness of the map product provided to users.

Description

technical field [0001] The invention belongs to the technical field of navigation, and in particular relates to a data checking method and device used in the production of navigation electronic maps. Background technique [0002] Navigation systems are becoming more and more popular in today's vehicles, especially in mid- to high-end cars. The navigation system performs route guidance to a predetermined destination selected by the user. Both the route guidance and the user's operation can be performed verbally through the voice control / recognition system and / or through the display device. [0003] Navigation databases for vehicles include navigation electronic map databases typically stored on removable storage media such as CDs or VCDs. In order to ensure that accurate navigation information can be provided to users, it is necessary for designers to check the correctness of the data in the navigation electronic map database. Currently, the data checking methods used in th...
