Application on Vehicle Detector using Laser Ranging Image Sensor

In traffic control systems, the vehicle detectors play a central role in collecting information. As information gathering equipment, there are many types of current vehicle detectors, such as ultrasonic type, loop coil type, and image type. But there are problems such as reduced accuracy due to temperature and wind, maintainability problems, and reduced accuracy at night. Therefore, in this research, we are considering using a Laser Ranging Image Sensor that can obtain an image including the distance as a new vehicle detector. In this paper, we first examined the sensor installation conditions. And then we proposed vehicle detection method for Laser Ranging Image Sensor for One-lane detection and Multiple-lanes detection. Finally, we conducted the demonstration experiment of vehicle detection and compared with the few public information of traditional vehicle detectors. From experiment results, we confirmed that for One-lane detection, it is excellent in accuracy. For Multiple-lines detection, it also has sufficient detection accuracy and can be further improving. In addition, as a new vehicle detector, it is excellent in installation and maintenance than traditional vehicle detectors.
