CARRIDA Software Engine

Hardware-Independent Software Engine, running Windows® and Linux® on PC and ARM® Architectures

ALPR/ANPR Software Engine

Vision Components’ Carrida Software Engine is a powerful OEM Library, which is easy to integrate into existing security and surveillance applications. The software tool assures reliable high-speed recognition of number plates/license plates.

Advantages of CARRIDA

The software is resistant against changing and difficult lighting conditions. Furthermore, it is well suited for stationary systems and also for mobile systems when coupled with a small lightweight compact camera. The VC ALPR software (Automatic License Plate Recognition Software) can be called from any C and C++ projects via API, allowing broad range of applications.

The VC ANPR software (Automatic Number Plate Recognition Software) is quick and easy to set up and can also be trained to read codes reliably on boxes, containers or similar, even if special fonts or symbol codes have to be detected. For the result’s data transfer standard network protocols are available. The recognition accuracy of more than 96% includes identifying damaged plates and angle correction.
