Problems solved by technology

[0003] Image processing generally uses pixels as the basic unit of processing. For a 128×128 image, the number of pixels reaches 16384. This value is very large, which leads to a very high time complexity of the algorithm.

Abstract

The invention provides a vehicle navigation system. The vehicle navigation system comprises a line management module, a data processing module, a map storage module and an offline navigation module, wherein the offline navigation module is connected with the data processing module and the map storage module, the line management module is used for acquiring and sending road images and vehicle position information to the data processing module, the data processing module recognizes the road images on the basis of super pixels, the map storage module is used for storing offline maps, and the offline navigation module is used for navigating vehicles according to road recognition results, vehicle positions and the offline maps. The vehicle navigation system has the benefit as follows: offline navigation and rapid navigation of the vehicles are realized on the basis of offline map storage and super pixel images.

Description

technical field [0001] The invention relates to the technical field of navigation, in particular to a vehicle navigation system. Background technique [0002] Most of the existing navigation systems are online navigation. On the other hand, the speed of image processing restricts the level of vehicle navigation. [0003] Image processing generally uses pixels as the basic unit of processing. For a 128×128 image, the number of pixels reaches 16384. This value is very large, which leads to a very high time complexity of the algorithm. If some pixel points satisfying specific conditions are formed into a set, and these sets are used as the basic unit of processing, the time required by the algorithm will be greatly shortened. Superpixel generation is an efficient way to cluster pixels into ensembles. Image superpixel is to gather pixels with similar attributes into a region to represent the image instead of pixels. The process of image superpixel generation is to combine adja...
