Full Description
Background
Transportation and vehicle classification systems are becoming smarter and more automated. For example, electronic toll collection systems have been introduced and drivers are not required to stop, eliminating road delays. New technologies have also been added to these systems that enable service providers to acquire data on the type of vehicles that are utilizing their amenities as well as vehicle identification for safety and control purposes.
Technology
UCR researchers have developed a method and system for vehicle classification using video imaging. The novel invention entails a vehicle ground clearance measurement along with a video camera that captures a travelling vehicle and categorizes it into a vehicle class. The method addresses an important challenge with current methods and systems - that of reliance on side views of the vehicle which can be easily obstructed by other vehicles.
Advantages
- Classifies vehicles into one of six classes: sedans, pickups, minivans, SUVs, buses and trucks
- Camera imaging of the rear end of vehicles for a more accurate classification
Suggested uses
- Vehicle identification readers for toll roads – provides information on the type of vehicles that are using the tolls as well as an added security measure for violators
- Substitute parking attendants – automatic classification of vehicle for parking entrance & exit payment systems
- Other safety and control system products
