The software for detection and reading of license plates developed by SLR Engineering can be used for applications in traffic monitoring, and traffic planning. In this case license plates are extracted either from pre-recorded video sequences, or in live mode using a PC with attached camera. The SLR Engineering smart camera supports this function as well. The SLR Engineering ALPR software extracts the license plates from the video source and merges multiple readings into one result. The license plate string is enhanced with a timestamp and then stored in a file. The license plate strings can be hashed so that they are transformed into an ID which is unique (and later re-identifiable on another reading), but not connected to the original license plate string.
