SimpleLPR is a software component for vehicle license plate recognition. It has a very simple programming interface that allows applications to supply a path to an image or a buffer in memory and return the detected license plate text and its location in the input image. It can be used from C++, .NET-enabled programming languages, or Python. Integration is simple and straightforward, as demonstrated by the examples provided with the SDK. Typical detection rates range between 85% and 95%, provided the license plates are in good condition, free of obstructions, and the text height is at least 20 pixels. You can download the user's guide from https://www.warelogic.com/doc/SimpleLPR3.pdf, and the class reference for .NET from https://www.warelogic.com/doc/SimpleLPR.chm.

Code example: using System; using System.Collections.Generic; using SimpleLPR3; // Create an instance of the SimpleLPR engine EngineSetupParms setupP; setupP.cudaDeviceId = -1; // Select CPU setupP.enableImageProcessingWithGPU = false; setupP.enableClassificationWithGPU = false; setupP.maxConcurrentImageProcessingOps = 0; // Use the default value // Create the SimpleLPR engine ISimpleLPR lpr = SimpleLPR.Setup(setupP); // Enable country templates for Brazil lpr.set_countryWeight("Brazil", 1.0f); lpr.set_countryWeight(countryId, 1.0f); // Create a processor object IProcessor proc = lpr.createProcessor(); // Use the analyze version that takes the path to a file List<Candidate> cds = proc.analyze("image.jpg"); // Iterate over all candidates foreach (Candidate cd in cds) { // Iterate over all country matches foreach (CountryMatch match in cd.matches) { Console.WriteLine("Text: {0}, country: {1}", match.text, match.country); } }
