A GPS-based real-time navigation road condition system and navigation method

Abstract

The invention provides a real-time navigation road condition system based on global positioning system (GPS). The system comprises a positioning module, a digital map, a map matching unit and a reminding unit; the system is characterized by further comprising a video monitoring unit, an image acquiring unit, an image processing unit, an integrated information processing unit and the reminding unit, wherein the video monitoring unit is used for acquiring peripheral road condition videos; the image acquiring unit is used for acquiring key images from the videos obtained by the video monitoring unit; the image processing unit is used for obtaining the image command information from the key images; the integrated information processing unit is used for integrally processing GPS and image information and obtaining the final command information; and the reminding unit is used for informing users with the final command information. The system has the beneficial effects that more accurate and effective navigation information can be supplied for drivers more precisely, and conditions of conventional GPS navigation errors and the non-timely updated digital map are effectively avoided.

Description

technical field [0001] The invention belongs to the field of road condition navigation, in particular to a GPS-based real-time road condition navigation 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 the driver appropriate guidance. But the existing GPS navigation system mainly has the following problems: [0003] Due to the problem of GPS a...

AI Technical Summary

Problems solved by technology

[0003] Due to the accuracy of GPS, the error is generally within tens of meters. For more complex intersections or overpasses, especially where there are several intersections or intersections with similar positions, this error can easily lead to fatal navigation errors.

Misleading drivers to miss the correct route

[0004] In addition, due to the rapid development of highways, there are often newly built routes, or due to other reasons, the road conditions in the city have undergone relatively large changes, but the electronic map built in GPS often needs to be updated for a period of time, which is somewhat different from the actual situation. A certain lag, easy to give wrong guidance to the driver
