Setting up the CARMEN-Auto program module is performed in the following way:
Enter the value of minimal validity of recognition in percent in the Minimum validity of LP type recognition field (3). Validity is defined by the degree of similarity between results of recognition and the LP template and it allows distinguishing the LP from other marks on the vehicle.
The validity is displayed in the List of parameters of the Active monitor box.
Setting up the CARMEN-Auto program module is completed.
For the best quality of recognition consider the following characteristic while the CARMEN-Auto configuring:
The less recognizers are created on the one computer the higher speed of video processing because the speed of video processing is shares between all created recognizers. Low speed of processing results in plate recognition delay and bad quality of recognition.
Here's approximate data of speed of video processing:
For the Common characters template:
For other templates:
These data can differ decreasingly of frequency of processed frames at different lighting conditions, on different processors etc.
