Description
The present invention relates to a road traffic information providing system and method, and more particularly, to a road traffic information providing system and method using image processing technology.
Conventionally, a navigation system of a vehicle has been started at a basic level that indicates a static situation stored in a map database with respect to a road that coincides with the position and direction of the vehicle based on the map database and the vehicle position. However, Integrated with the information providing system, it is possible to reflect the traffic volume information on the map in real time, and furthermore, it has developed to the level of guiding the fast road reflecting the traffic situation in real time.
However, in the existing road traffic information providing system, for example, when passing time information for passing vehicles having a specific transmitter between two detectors installed in a specific road section is cumulatively received by a central server for a predetermined time Next, since the information is processed and updated appropriately, the road traffic volume information received by the driver is information based on traffic volume at least several minutes to several tens of minutes ago.
For example, since the traffic volume increases rapidly in the hours of leaving the office, the roads indicated as smooth in traffic volume information about a dozen minutes ago are often clogged.
In addition, the function of the road may be deteriorated due to temporary reasons such as a contact accident, but it may take longer to recover due to reasons such as pavement construction. When a driver does not know the situation ahead, It is difficult to predict.
In the case where an accident or emergency such as an accident occurs in front of the traveling path of the vehicle and the road suddenly paralyzes, the existing road traffic information system may not be able to detect a traffic accident due to the fact that, for example, The transit time information can not be newly received for a considerable time and the incorrect traffic amount information indicating that the traffic is smooth according to past transit time information may be provided. In such a case, the driver who has entered the road by trusting the wrong traffic volume information may be embarrassed.
Conventional traffic volume analysis that considers vehicle type is classified by vehicle type and recorded on a check sheet or integrated, or image data is acquired by using a CCD camera or the like image acquisition device, Passive or semi-passive method of knowing the number of units. In addition, there is a technique for distinguishing and analyzing the type of vehicle by size, medium, small size according to size.
However, the above methods are passive, and only a rough classification of vehicle types such as size is possible, so that the traffic volume analysis based on the type of vehicle can not be accurately performed.
SUMMARY OF THE INVENTION The present invention has been conceived to solve the above-mentioned problems, and it is an object of the present invention to provide a digital image processing method, And to provide a system and method for providing the same.
