Media Server can detect and read number plates that appear in video.
To detect and read number plates in video
Create a new configuration to send to Media Server with the process
action, or open an existing configuration that you want to modify.
In the [Session]
section, add a new analysis task by setting the EngineN
parameter. You can give the task any name, for example:
[Session] Engine0=Ingest Engine1=ANPR
Create a new section in the configuration file to contain the task settings and set the following parameters:
Type
|
The analysis engine to use. Set this parameter to numberplate . |
Input
|
(Optional) The image track to process. If you do not specify an input track, Media Server processes the first track of the correct type that is produced by the ingest engine. |
Location
|
(Set this or |
LocationWithPriorities
|
(Set this or For example, if you are recognizing number plates in France but are near the border and also want to recognize plates from Germany and Belgium, you might set |
Region
|
(Optional) The region of interest (ROI) to monitor for number plates (left, top, width, height). If you do not specify a region, Media Server detects and reads number plates anywhere in the scene. |
RegionUnit
|
(Optional) The units used to specify the position and size of the region of interest (pixel or percent ). |
Sensitivity
|
(Optional) The confidence level required to detect a number plate. |
MinValidScore
|
(Optional) The average character score required for a number plate to be recognized. |
For example:
[ANPR] Type=numberplate Location=GB RegionUnit=percent Region=20,10,60,90 Sensitivity=14
For more information about the parameters that customize number plate recognition, refer to the Media Server Reference.
Save and close the configuration file. Micro Focus recommends that you save your configuration files in the location specified by the ConfigDirectory
parameter.
