Since 2012, the Raspberry Pi Single-board computer series have developed to an affordable yet powerful processing platform. In its latest issues, the computer features a quad-core processor with gigabytes of RAM. Its price point and capabilities have made it a good choice for close to any (embedded) application.

Q-Free confirms these possibilities and delivers the offering for world-leading Intrada® ALPR software as application or OEM module for the various Raspberry Pi models. Intrada ALPR automatic license plate recognition runs natively on the embedded ARM processor, with support for license plates all over the world. To this purpose, field tests have proven suitability for live video and image processing, with applicability in monitoring, parking and access control applications.

With Intrada Live for Raspberry Pi you can connect to any IP camera and trigger on passing vehicles. You can also read video directly from the onboard CSI interface. Intrada Live reports triggers and identifications to a local application or to any remote server. When choosing for SDK integration, you can feed frames directly to the Intrada shared library for automatic license plate recognition.
