Abstract
A toll violation enforcement system that contains a capture unit that receives a trigger signal and takes vehicle images of passing vehicles. A lighting unit configured to operate continuously is provided to establish a major lighting source incident on the vehicle. A processing unit is provided that processes the vehicle image and controls the settings employed by the capture unit. The processing unit preferably contains a plate location module for extracting an original resolution license plate area image from a first vehicle image; an exposure control module for controlling the exposure setting on the capture unit to provide consistent intensity of the license plate area; a resolution reset module for changing the image resolution for a second vehicle image; an image enhancement module for brightening pixels of the second vehicle image; and an image compression module for compressing the license plate area image and second vehicle image to a predetermined format.
