At the same time, my country's road construction is also developing continuously, and tens of thousands of kilometers of roads are added every year. Drivers often need the assistance of a navigation system when passing through unfamiliar areas. The existing GPS navigation system relies on GPS and GIS. The system can accurately give the driver proper guidance, but the development of roads is changing with each passing day, and because the urban roads often change, and the electronic map often takes a period of time to update, which brings inconvenience to the driver and is likely to cause traffic accidents

example
[0037] When the driver is driving the vehicle, the video monitoring unit of this system starts to work to capture real-time changes in the surrounding road conditions. The image data unit samples the video images according to the set frequency, which can be set according to specific conditions , can take 1hz or higher frequency, organize it into frame images with a certain time interval, and judge whether it belongs to the key image predefined by the system according to the content in the frame image. informational image. The image processing unit processes the key image obtained in the previous step, extracts the graphic indicated by the road sign in the key image, and compares it with the pre-stored image in the memory, and if the comparison is consistent, records it and passes The character recognition unit recognizes the words on the sign and transmits the information to the reminder unit, and the reminder unit plays the above information to the driver through the voice ou...

The invention provides an immediate navigation road condition system which comprises a video monitoring and control unit, an image obtaining unit and an image processing unit and. The video monitoring and control unit is used for obtaining a video of a nearby road condition, the image obtaining unit is used for obtaining a key image from the obtained video of the video monitoring and control unit, and the image processing unit is used for obtaining order information form the key image and used for informing a user of the order information. The invention further provides a navigation method of the immediate navigation road condition system. The navigation method includes following steps of obtaining an immediate road condition video, confirming the key image from the immediate road condition video, obtaining the order information from the key information, and informing the user of the order information. The immediate navigation road condition system and the navigation method have the advantages of being capable of immediately and effectively aiming at road condition changes to give a driver immediate and accurate road surface navigation information.
Description
technical field [0001] The invention belongs to the field of communication and navigation, and in particular relates to an instant navigation road condition system and a navigation method. Background technique [0002] In recent years, under the background of maintaining rapid economic growth, automobiles have gradually entered ordinary households. The State Information Center predicts that my country will surpass the United States around 2015, and by then, the market capacity will exceed 17 million vehicles. At the same time, my country's road construction is also developing continuously, and tens of thousands of kilometers of roads are added every year. Drivers often need the assistance of a navigation system when passing through unfamiliar areas. The existing GPS navigation system relies on GPS and GIS. The system can accurately give proper guidance to the driver, but the development of roads is changing with each passing day, and because the urban roads often change, and ...
