Traffic Sign Recognition

Keywords

How does traffic sign recognition work?

A traffic sign recognition (TSR) system uses the forward-facing camera fitted to a car to scan the roadside and ‘read’ traffic signs indicating the speed limit. The pictures from the camera are run through software in the TSR system to recognise the characters and a message of the legal speed limit is then sent to a display in the driver’s instrument panel. This is permanently displayed, so the driver always knows what the speed limit is, allowing them to stay within the law.
