Abstract

The invention discloses an intelligent vehicle navigation system, and the system has a scene recognition function. The system comprises an image preprocessing module, an image extreme point detection module, an image feature point positioning module, a main direction determining module, a feature extraction module, and a scene judgment module. The image feature point positioning module determines extreme points serving as feature points through removing low contrast points, sensitive to noise, of all extreme points and unstable edge points. The main direction determining module is used for connecting any two adjacent peaks in a gradient direction histogram of the feature points so as to form a plurality of sub-lines, and merging the adjacent sub-lines with the similar slope in a length direction to form one line, and then enabling the direction of the optimal line of the plurality of lines to serve as the man direction of the feature points. The system is high in scene recognition precision, and is high in speed.

Description

technical field [0001] The invention relates to the field of vehicle navigation, in particular to an intelligent vehicle navigation system. Background technique [0002] If the vehicle can judge the scene during driving and switch to different navigation modes, it will undoubtedly bring a better experience to the driver and passengers. However, current car navigation systems do not have a scene judgment function. In addition, in order to process a large amount of image data, it is necessary to improve analysis processing efficiency and accuracy. Contents of the invention [0003] In view of the above problems, the present invention provides an intelligent vehicle navigation system. [0004] The object of the present invention adopts following technical scheme to realize: [0005] An intelligent vehicle navigation system is provided, the navigation system has a scene recognition function, including: [0006] (1) Image preprocessing module, which includes an image conver...
