Use of Embedded Linux for Toll Estimation System Based on Vehicle Detection

There are many toll collection systems implemented in India. But when factors like reliability and cost matter there is a need of new efficient system. This presented system can be implemented in Embedded Linux platform with the help of OpenCV library. The system is designed using Embedded Linux development kit (Raspberry pi). The input to the system is a camera which captures images of vehicles passing through the toll booth. Depending upon the key pressed by the tollbooth controller, current frame will be passed to the Raspberry pi, which is responsible for all the core processing like vehicle detection and other calculations. Depending on the features (mainly area) of vehicle, classification of vehicles basically as light and heavy is done. Then it will access database (containing standard information) and according to the type of the vehicle, appropriate toll is charged. This system can also be used to count number of vehicles passing through the toll booth
