Snapshot system for bus lane

Abstract

The invention relates to the field of traffic monitoring, in particular to a snapshot system for a bus lane. According to the snapshot system for the bus lane, firstly, whether a road segment is the bus lane and whether the present time is within a traffic control time are determined according to GPS data sent by a GPS positioning device and the traffic control time, and video capture is conducted on the front end or the rear end of a bus through high-definition cameras, each analog video signal is converted into a digital video signal. Secondly, vehicle detection is conducted within a detected lane line on each frame of an image which is captured, a vehicle is traced, and images are stored to be used as a snapshot result. Thirdly, license plate location is conducted on the snapshot images, double-line license plate distinguish and separation, license plate character segmentation, and license plate character recognition are conducted, whether the vehicle is repeatedly detected is determined according to a recognition result, whether the vehicle is an illegal vehicle is judged according to a legal license plate base if the vehicle is not detected repeatedly, and three snapshot images which are captured are stored and the recognition result are stored and the recognition result is sent to a background data processing subsystem if the vehicle is illegal.

Description

technical field [0001] The invention relates to the field of traffic monitoring, in particular to a bus lane capture system. Background technique [0002] In recent years, in order to solve the problem of urban road congestion, many cities across the country have opened bus lanes and implemented Bus Rapid Transit (BRT) under the policy of "prioritizing the development of urban public transport". There are obvious effects in reducing pressure and improving transportation capacity. However, in actual operation, the effect is not as good as expected. In terms of driving speed and punctuality, some cities are far from reaching the expected indicators before construction. In addition to facility factors such as platform design and road allocation, illegal occupation of bus lanes by social vehicles is the most important reason. In this context, the bus lane capture system was born. [0003] The current bus lane capture system has the following problems: [0004] 1. Mistake: Th...

AI Technical Summary

Problems solved by technology

[0004] 1. Mistake: The bus is not in the dedicated lane, the bus lane is not in the restricted time period, and the interfering vehicles on the surrounding roads, etc., can easily lead to mistaking

[0005] 2. Illegal data: Using high-definition smart cameras to automatically shoot illegal vehicles on dedicated lanes can easily lead to repeated shooting of the same road section and the same time period, resulting in multiple unreasonable violation data of the same vehicle

[0006] 3. A large amount of transmitted data: all the captured license plate pictures are transmitted to the background data processing subsystem, which will easily lead to a large amount of transmitted data, high transmission cost, and slow transmission speed
