Description

Technical Field

[0001] This invention relates to the field of traffic management technology, specifically to a two-way evidence collection and recording method for traffic violations by large vehicles. Background Technology

[0002] Traffic accidents involving large vehicles remain consistently high. Some large trucks that could detour outside the city choose to navigate through congested urban areas. Many large trucks, in their rush to transport more goods, disregard traffic safety, frequently speeding, overloading, running red lights, and recklessly overtaking at night. Despite continuous and targeted efforts to regulate the traffic behavior of large vehicles and ensure traffic order, traffic violations by trucks persist, and traffic accidents remain high.

[0003] Existing electronic traffic enforcement systems use rear-view cameras to capture traffic violations. However, for large vehicles, due to their length, the first position in the recorded photo cannot capture the entire rear view of the vehicle, failing to meet the industry standard GA / T832 "Technical Specification for Image Evidence Collection of Road Traffic Safety Violations," which requires images to contain clearly identifiable panoramic features of the front or rear of the motor vehicle. Furthermore, the rear license plate is easily obscured by the vehicle's cargo box, making it difficult for the electronic traffic enforcement system to effectively see the license plate number. Additionally, many trucks travel on construction sites and other road sections where the rear license plates are heavily contaminated with dust and mud, making them difficult to record effectively. Moreover, the rear license plates of large vehicles in China are often double-layered, with the characters on the first layer being too small to be easily identified in video and photographic records. These factors result in insufficient evidence for traffic violations, hindering the imposition of penalties. Therefore, a two-way evidence collection method for traffic violations by large vehicles is proposed. Summary of the Invention

[0004] The purpose of this invention is to provide a two-way evidence collection and recording method for traffic violations by large vehicles, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a method for two-way evidence collection and recording of traffic violations by large vehicles, comprising the following steps: S1. Record 3 sets of photos of vehicles that run red lights through the two-way evidence recording system. Record a total of 6 photos from the front and rear of the vehicle. For evidence of running red lights, at least three photos of the violation must be recorded. S2. Through the two-way evidence collection and recording system, record 6 photos of vehicles that do not drive in the correct lane, with the front and rear of the vehicle being recorded simultaneously. For the evidence of violations of driving in the correct lane, record the violations at least three locations. S3. The two-way evidence collection and recording system takes three sets of photos of vehicles that illegally cross solid lines, and records a total of six photos from the front and rear of the vehicle. These three high-definition panoramic images from different positions show the illegal process, including photos of the vehicle crossing solid lines. S4. The two-way evidence collection and recording system detects, captures, records, saves, and identifies all vehicles passing through each lane. S5. Detect, capture, record, and identify vehicles that violate traffic restrictions by using a two-way evidence collection and recording system; S6, the two-way evidence recording system can determine the status of traffic lights through video detection and analysis; S7. Clearly record images of vehicles traveling in the wrong direction through a two-way evidence collection and recording system. The images must meet the requirements of GA / T832. S8. Accurately record traffic flow through the two-way evidence collection and recording system; the information must comply with the requirements of GA / G920. S9. Use the two-way evidence collection and recording system to record video footage of traffic violations that is easy to preserve, and use this video footage as evidence for administrative review. S10. The two-way evidence collection and recording system has automatic vehicle license plate recognition. The character library used for license plate recognition should be complete and able to recognize license plates specified in GA36, armed police vehicle license plates, and military vehicle license plates. Based on the captured target photo, it can automatically complete the recognition of license plate number and license plate color, and can also recognize new energy vehicle license plates.
