In the source code ALPRCoreWorkerNeuralLabs.cpp, the ALPR has the result prepared and the program processes the result given in the method CALPRWorkerCoreNeuralLabs::internalAddRead().

For the full information of the parameters given by the result, the struct tResults has them defined, which is documented in the VPAR's given documentation (/docs/[ ENGLISH ] VPARMT C++ - Reference Manual.pdf).

The only caveat is that the parameter vlFormat is a number that references the internal country code of the license plate. The complete list of the country codes can be found in the VPAR's documentation (/docs/VPAR 7 - Valid Country Codes for each Region.pdf or in the VAPR's header file countrycodes.h).
