Embedded vision systems control traffic

The hardware-independent OEM library achieves a typical reading accuracy of more than 96% for international license plates, including damaged, dirtied, or skewed plates. Carrida reads all common still image and movie formats from memory or file, detects all plates displayed in one image, and recognises characters with a minimum height of 12px. It works reliably at car speeds to 200km/h.

A dedicated parking management tool facilitates setup and organisation of access control systems via black/white lists. Accompanying the software tools, miniature smart camera solutions were also showcased. The Carrida Cam is easy to integrate into existing security and surveillance applications. It runs the Carrida engine and makes any gate system or similar application smart, connected simply via an Ethernet port. At a power consumption of less than 3W, it is also suitable for standalone operation in mobile and stationary systems.

Both a board camera and an enclosed version are available. At 88 x 58 x 36mm, the Carrida Cam is among the world’s smallest standalone ALPR/ANPR cameras.
