Wagon Number Recognition SDK


Current Version: 1.1.3

DTK WNR SDK (Wagon Number Recognition) is a software development kit designed for software developers who want to integrate freight wagon number recognition into their software products. DTK Wagon Number Recognition engine detects and recognizes 1520 mm gauge railways eight-digit wagon numbers (used in the former-USSR and now the CIS and Russia) from various video sources (IP cameras, video files, video capture devices) and still images (JPEG, PNG, BMP). The fast and stable WNR engine is built on the latest technologies and algorithms, provides highly accurate recognition from the real-time video at a resolution up to 1920x1080 (Full HD).

It is compatible with standard IP camera protocols and encodings (such as MJPEG/HTTP, H.264/RTSP) and custom video sources, providing decoded (RAW) frame images to the recognition engine. The SDK can be used with the most popular programming languages like C++, C#, VB.Net, Java, Python, etc. The documentation, help files, and sample applications (C++, C#, VB.NET, Delphi, Java, Python) are included in the SDK.
