A real-time map update device and method based on big data

Abstract

The embodiment of the present invention discloses a real-time map update device based on big data, including a collection device for collecting image information, a mobile terminal for preprocessing data information and generating secondary map navigation model information, and the update method is as follows: The acquisition device collects several sub-data packets in real time when pedestrians walk along the navigation map path, and imports and uploads them to the big data processing module. The big data processing module obtains the image information collected by the acquisition device and performs data processing and analysis on it. After that, After the analyzed data is transferred to the data storage processing module, the present invention enables pedestrians to collect information such as road conditions in their walking trajectories during the process of walking through the combination of the mobile phone terminal and the collection device, so that the map route of the pedestrian can be obtained in real time The changes and reasonable planning are more time-sensitive, and at the same time, some areas that are vaguely represented on the map are fully displayed, avoiding detours and other situations.

Description

technical field [0001] The embodiments of the present invention relate to the field of map technology, and in particular to a device and method for real-time updating of maps based on big data. Background technique [0002] Big data is a large-scale data collection, which has four characteristics: massive data scale, fast data flow, diverse data types and low value density. Maps use lines, symbols, colors, Text notes, etc. describe graphics showing the physical geography, administrative regions, and social conditions of the earth's surface. With the advancement of science and technology, the concept of maps is constantly evolving. For example, maps are regarded as "images and symbolic models reflecting natural and social phenomena", and maps are "carriers of spatial information" and "transmission channels of spatial information". Wait, anciently Figure 1 Generally, maps are drawn on parchment or stone slabs. The carrier of traditional maps is mostly paper. With the develop...

Problems solved by technology

[0004] For this reason, the embodiment of the present invention provides a real-time map update device and method based on big data. Through the combination of mobile terminal and collection device, pedestrians collect information such as roads in their walking tracks during walking. When the situation is found, it will be uploaded to the big data processing module immediately, so that the pedestrian's map route can be changed in real time and reasonably planned to solve the problem that in the existing technology, there is only a large range in some areas in the current pedestrian map. When pedestrians follow the Detours are very easy to occur when walking on the map. At the same time, once the road situation occurs, pedestrians need to change the route again. The operation is cumbersome and time-consuming, and it also wastes a lot of time for pedestrians.
