Sighthound’s AI Software Now Reads License Plates

License plate detection and recognition now available on Sighthound Cloud and for edge deployments with Sighthound Sentry

Palo Alto, California - March 23, 2017 - Sighthound, Inc. today announced the release of a deeply learned license plate detection and recognition API in its Cloud service and as part of its Sighthound Sentry software. The software scans images or videos and uses Sighthound’s proprietary deep computer vision algorithms to detect and read license plates as well as recognize the country/state of origin. In addition, it also provides confidence scores for each of the above to help with custom development.

The license plate detector can find license plates in a much broader range of real world deployments than traditional single lane focus cameras, and the recognition models are not only robust to license plates from many different parts of the world but also to natural variations in conditions. The software is designed to return the state for US license plates and country for certain EU countries. Demonstrations of the software running on an nVidia TX1 edge device and in the Sighthound Cloud are available at

The deeply learned system is significantly more accurate than any open source or commercial alternatives to which Sighthound had access. Benchmarks are available in a white paper here: The technology draws upon Sighthound’s experience in building fast, deep Convolutional Neural Networks (CNNs) to perform complex tasks accurately with much more speed and much less data than in the past.

License plate recognition joins Sighthound’s vehicle make, model and color recognition in a new Vehicle Product Suite that is available to companies in fields such as law enforcement, traffic control, toll monitoring, and motor vehicle transportation.

Sighthound makes it easy for developers to get started by offering free tutorials, sample code, and documentation to help integrate its APIs into their own applications.

Developers can use the free Sighthound Cloud API at Paid accounts (Basic, PRO, and Enterprise) have access to production servers for commercial use and begin at $49 per month.
