Video surveillance system is widely used in the current traffic monitoring system. Existing commercial image processing system works well in vehicle detection and tracking, but it has difficulties in vehicle classification if the camera is not calibrated. A priori camera calibration is used in many systems, which is a complicated process. In this paper, a very simple roadside camera calibration is...
Many vision-based automatic traffic-monitoring systems require a calibrated camera to compute the speeds and length-based classifications of tracked vehicles. A number of techniques, both manual and automatic, have been proposed for performing such calibration, but no study has yet focused on evaluating the relative strengths of these different alternatives. We present a taxonomy for roadside camera...
Speed cameras are systems which normally include a camera, a calibration system, speed estimation software, and a vehicle recognition system (which includes a vehicle type detector and a LPR system). These systems are normally used to detect and identify vehicles disobeying a speed limit in a road. While these systems are used widely in the world, their use in Iran is restricted due to various difficulties...
Intelligent driver assistance systems, such as lane departure warning, extract 3D information of the road geometry from a camera. Therefore, the transformation between the image and the ground plane has to be determined with a very high accuracy. Conventional calibration methods are usually a compromise between the accuracy and a preferably small effort for the calibration set-up. In this paper, we...
