How was the line pressed captured? Revealing the technology of photographing traffic violations
Recently, "shooting under the line" has become a hot topic, and many car owners are curious about the capture principle of traffic cameras. This article will combine the hot content of the entire network in the past 10 days, analyze the principles, technical methods and common misunderstandings of line capture, and present key information through structured data.
1. Technical principles of line-pressing and capturing
Line capture mainly relies on high-definition cameras and intelligent algorithms. When a vehicle crosses a solid or dotted line, the camera will complete the capture through the following steps:
| steps | Technical implementation |
|---|---|
| 1. Image acquisition | Camera above 5 million pixels, shooting at 30 frames per second |
| 2. License plate recognition | OCR technology, accuracy rate exceeds 99% |
| 3. Line pressure judgment | AI algorithm analyzes the relationship between tires and markings |
| 4. Data upload | 4G/5G real-time transmission to traffic control system |
2. Recent hot case data
According to data released by local traffic control departments, illegal cases of line crossing in the past 10 days show the following characteristics:
| city | Average number of snapshots per day | High frequency illegal road sections |
|---|---|---|
| Beijing | From 1,200 | East Third Ring Road Guomao Bridge |
| Shanghai | From 980 | Yan'an Elevated Road |
| Guangzhou | From 850 | Tianhe Interchange |
| Shenzhen | From 1,100 | Shennan Avenue |
3. Analysis of common misunderstandings among car owners
1."It is not illegal to press the rear wheel line": It is illegal to actually press the front or rear wheel line. The system will record the complete contact process between the tire and the marking line.
2.“I won’t be photographed on rainy days.”: The new camera is waterproof and can still work normally in bad weather.
3."It doesn't matter if it's temporary.": As long as the tire continues to press the line for more than 3 seconds, the system will determine it as an illegal act.
4. New trends in technological upgrading
The latest snapshot system deployed in 2023 has the following new functions:
| Technology | Function description | Application city |
|---|---|---|
| Multiple target tracking | Monitor 6 lanes simultaneously | Hangzhou, Chengdu |
| 3D modeling | Three-dimensional restoration of the illegal process | Beijing, Shanghai |
| edge computing | Process data locally in real time | Shenzhen, Guangzhou |
5. Driving advice to avoid crossing the line
1. Observe the lane signs in advance and start changing lanes at least 100 meters in advance.
2. Keep the distance between vehicles and avoid following the vehicle in front too closely, causing you to be forced to cross the line.
3. Use the lane-level navigation function of the navigation software to obtain accurate lane guidance.
4. On unclear road markings, follow the arrows on the road.
By understanding the technical principles and latest trends of line capture, car owners can better abide by traffic rules and ensure driving safety. The traffic control department also stated that the ultimate purpose of the intelligent capture system is to regulate driving behavior rather than simply punishing drivers.
