Road Sign Detection and Recognition System

Québec’s Ministère des Transports (MTQ) is responsible for highway management in the province, including regular inventory taking. Authorities often lack reliable information for this purpose. Inventories require a great deal of time and resources to update, which makes it hard to do so on a regular basis. Road sign inventories are a good example. MTQ turned to us to develop new technologies capable of conducting inventories quickly and efficiently.

Working with MTQ, we developed a new system that automatically generates road sign inventories. This system—known as RSR for Road Sign Recognition—automatically detects, recognizes, and localizes road signs from video images. This system accelerates inventory data extraction and review, thereby reducing the cost of accurate road sign surveys.
