Problems solved by technology

However, in real life, due to complex and changeable road conditions and changes in driving speed limits, drivers cannot timely and effectively understand the contents of roadside traffic signal boards.
The road condition information stored in the GPS positioning system cannot be updated or the update speed is slow. After a long time, it is easy to cause wrong guidance to the driver.

Embodiment Construction

[0026] The implementation method of the present invention is described in detail below in conjunction with accompanying drawing:

[0027] figure 1 The present invention shown includes an image input system, a central processing system, a voice prompt system, and a video display system. The image input system is connected to the central processing system, and the central processing system is also connected to the voice prompt system and the video display system respectively.

[0028] Described central processing system comprises:

[0029] The target image interception system calculates the edge information of the traffic signal board according to the input image, determines the position of the traffic signal board area, and intercepts the information content of this part of the image;

[0030] The image distortion processing system performs image correction on the information content of the intercepted part of the image;

[0031] The automatic recognition system divides the c...

Abstract

The invention relates to an automatic identification warning system of a vehicle-mounted traffic annunciator, comprising an image input system, a central processing system, a voice prompt system and a video display system, wherein the image input system is connected with the central processing system; and the central processing system is also respectively connected with the voice prompt system and the voice prompt system. The automatic identification warning system can accurately prompt drivers with real-time road condition information so that the drivers are easy to know the road condition information and avoid incompletely and mistakenly seeing traffic signal marks; and the automatic identification warning system has advanced image identification method and high identification rate and can realize the real-time updating of navigation software.

Description

technical field [0001] The invention relates to a navigation device, in particular to a vehicle-mounted traffic signal board automatic identification and warning system. Background technique [0002] Traffic signal boards are important signs to guide drivers to drive. In the daily driving process, the most frequent contact of drivers is these traffic signal boards indicating road conditions. The vehicle-mounted GPS positioning system currently on the market can effectively provide drivers with prompts for road selection and driving direction, and some products also provide road section information prompts, such as speed limit, steering, etc. However, in real life, due to complex and changeable road conditions, changes in driving speed limits, etc., drivers cannot timely and effectively understand the contents of roadside traffic signal boards. The road condition information stored in the GPS positioning system cannot be updated or the update speed is slow. After a long time...
