Attention!
ANPR를 구성하려면 다음 단계를 따르세요.
실시간 번호판 인식에 이 탐지 도구를 사용하려면 해당 매개변수를 예(2)로 설정하세요 (Configuring real-time vehicle license plate recognition 참조).
차량 진행 방향 감지 알고리즘을 선택하세요 (1)
번호판 좌표 기준—번호판 좌표가 위에서 아래로 이동하면 차량이 카메라 쪽으로 다가오는 것이고 아래에서 위로 이동하면 차량이 카메라에서 멀어지는 것입니다.
번호판 크기 기준—번호판 크기가 커지면 차량이 카메라 쪽으로 다가오는 것이고 작아지면 차량이 카메라에서 멀어지는 것입니다.
객체 도구 작동 모드를 선택하세요: 표준 또는 신경망 (2).
적절한 필드에서 ANPR를 위해 하나 이상의 국가를 선택하세요.(3).
Attention!
Analyzed framed are scaled down to a specified resolution (5, 1920 pixels on the longer side). This is how it works:
If the longer side of the source image exceeds the value specified in the Frame size change field, it is divided by two.
If the resulting resolution falls below the specified value, it is used further.
If the resulting resolution still exceeds the specified limit, it is divided by two, etc.
Note
Select the current license type (6).
| License | Description |
|---|---|
| Search in archive | Basic ANPR Search License. Attention! This type of license provides a 30-sec delay between the number recognition and the corresponding event (see Vehicle number plate recognition and search). |
Standard (25 FPS or 6 FPS) | The 25 FPS license has a priority. The 6 FPS license is used only if you don't have 25 FPS license. You cannot use the license plate recognition function if you have not purchased both licenses. |
Fast speed (25 FPS) | The "Fast" license allows you to process video feeds up to 25 FPS with a maximum vehicle speed of 150 km/h. You cannot use the license plate recognition function if you have not purchased the license. |
Slow speed (6 FPS) | The "Slow" license allows you to process video feeds up to 6 FPS with a maximum vehicle speed of 20 km/h. You cannot use the license plate recognition function if you have not purchased the license. |
Attention!
Set the maximum and minimum width of the vehicle license plate as a percentage of the FOV width (7, 8).
Attention!
The Minimum LP width parameter affects the CPU load as follows: the higher the parameter is, the higher the load.
Choose a processor to run detection on (9, see 번호판 인식(VT)을 위한 하드웨어 요구 사항, 검출 구성에 대한 일반 정보). In standard mode, detection runs on the CPU only. In neural network analysis mode, the algorithm runs on the NVIDIA GPU.
Attention!
Starting with Detector Pack 3.11, Intel HDDL and Intel NCS aren’t supported.
Set the number of frames required for LPR/ANPR (10). This is a necessary condition, but it is not sufficient for the first output. This condition delays the LPR output. This parameter allows increasing the reliability of the results, as well as hiding false positives.
If necessary, configure the advanced detection settings (see VT 번호판 검출 도구 미세 조정).
You can configure the ANPR area in FOV. The area is resized by moving the anchor points.
Note
Configuration of ANPR is now complete.
