Image Processing Application in Toll collection

چکیده
The toll rate charged for the usage of facilities such as a tunnel or a bridge is usually proportional to the number of axles possessed by a vehicle. However, it is sometimes difficult to determine the number of axles of a vehicle by the toll-booth operator and therefore, an automatic system that can identify the number of axles is sought. Instead of detecting the axle, wheels of a vehicle are tested and a method based on the Hough transform for detecting circles is proposed. As the system must be able to detect the correct number of wheels in real-time, sub-sampling based on the Haar Wavelet transform is applied. Experimental results show that the system is able to identify the wheel correctly and to process the input images in real-time.

Electronic toll collection (ETC) system has been a common trend used for toll collection on toll road nowadays. The implementation of electronic toll collection allows vehicles to travel at low or full speed during the toll payment, which help to avoid the traffic delay at toll road. One of the major components of an electronic toll collection is the automatic vehicle detection and classificati...
