To access the advanced settings in CAMMRA and customize the application according to your needs, follow these instructions:
Plate Size Min. and Max. (Default): The plate size settings determine the minimum and maximum size of license plates that CAMMRA will recognize. It is recommended to use the default values unless specific adjustments are required.
Number of Symbols: Set the range for the minimum number of symbols in license plates for the region or country templates. It is advised to keep this range as narrow as possible to ensure accurate recognition based on regional license plate patterns.
LPR Confidence Threshold: Adjust the LPR confidence threshold to determine the minimum confidence level required for a license plate detection. A threshold of 0.6 to 0.7 is typically recommended, striking a balance between detection rate and false recognitions. Lower thresholds increase the detection rate but may also result in more false recognitions.
Comparison of Blacklisted Plates: Choose the type of comparison for blacklisted plates:
Preferred Country: Specify the preferred country for license plate recognition. This helps improve country detection when multiple countries are involved.
Enable Make and Model Recognition (MMR): Toggle the MMR feature to enable or disable make and model recognition. If only license plate recognition (LPR) is required, it is recommended to turn off MMR. This is especially useful when capturing the rear side of vehicles.
MMR Confidence:
Set the confidence threshold (0-100) for make and model recognition. The optimal threshold depends on the task CAMMRA needs to fulfill. For accurate make and model recognition, a recommended range is 30-60. For type classification, a range of 10 is suggested
Security/HTTPS Settings:
To enhance the security of your CAMMRA application, you have the option to enable HTTPS encryption and use self-signed certificates. By turning on HTTPS encryption and utilizing self-signed certificates, you can ensure that the communication between the application and browsers is secure and protected. This helps safeguard the integrity and confidentiality of data transmission
