The MatcherSettings.xml file contains the settings for the techniques used by the ALPR matcher: OCR equivalence, number of character differences, and common and contiguous characters.
<Matcher>tags that define the settings for each type of matching scenario:
- Settings for matching plate reads with hotlists.
- Settings for matching a plate read against all other plate reads in the Genetec Patroller™ database.
- Settings for matching plate reads with permit lists.
- Settings for reconciling inventories in Security Desk.
The structure of the MatcherSettings.xml file allows you to have different behavior for the different enforcement scenarios. For example, to maximize your plate read accuracy rate in an enforcement scenario that includes both permits and hotlists, you’ll typically want to use only OCR equivalence for the hotlist matcher, but also allow one difference in the number of characters for the permit matcher to decrease false-positives.
