Traffic data online collection system and method

Abstract

The embodiment of the invention provides a traffic data online acquisition system and a traffic data online acquisition method. The system comprises a camera, an acquisition client connected with the camera, an acquisition server side connected with the acquisition client, and a Web server and an independent client connected with the acquisition server side. The method comprises an image capture step, a data acquisition step, a load balance judgment step, a recognition processing step, a storage step and a display step. By the system and the method, a common camera can recognize license plates of vehicles automatically, and the problems that the camera with a recognition function only captures but not processes or processes slowly in traffic rush hours are avoided effectively; after the adoption of the system and the method, a traffic data acquisition system can be configured in a general static state mode; and because of the load balance capacity in the system, the system and the method have dynamic adaptivity to complex changeable dynamic urban traffic conditions. In addition, queries can be published online in real time, so that the construction cost of traffic facilities is reduced, and the work efficiency and the accuracy are improved.

Description

technical field [0001] The invention relates to the field of intelligent transportation, in particular to a system and method for online collection of traffic data. Background technique [0002] With the increase of personal ownership of cars, the task of intelligent transportation facilities to manage cars is getting heavier and heavier. Traffic network cameras can be used to collect car license plate information to effectively manage traffic violations, random parking, inspections, etc. Even fight crime. At present, traffic network cameras collect license plate information by directly designing embedded programs for traffic network cameras, and adding intelligent license plate recognition functions inside traffic network cameras; traffic network cameras with license plate recognition functions use embedded license plate recognition technology Limited by hardware computing power and storage space, compared with the license plate recognition technology of the PC version, it...

Problems solved by technology

At present, traffic network cameras collect license plate information by directly designing embedded programs for traffic network cameras, and adding intelligent license plate recognition functions inside traffic network cameras; traffic network cameras with license plate recognition functions use embedded license plate recognition technology Limited by hardware computing power and storage space, compared with the license plate recognition technology of the PC version, it has a slower recognition speed and a lower recognition rate, and there may be cases where data can be collected but cannot be processed in real time during peak traffic hours. question

In addition, only a few companies in China have mastered the embedded license plate recognition technology and applied it to certain types of cameras, which directly leads to the high price of traffic network cameras with license plate recognition functions.
