A Vehicle Distance Measurement System Using the License Plate

An objective of this research is to develop a car distance detection system that detects the distance from the license plate, using the color of the license plate for analyzing and detecting the vehicle's rear section, and by designing the system to operate on a smartphone. The system will allow drivers to recognize and maintain the distance between vehicles with better efficiency and safety. The experimental result revealed that the system was able to detect and display the distance between vehicles correctly and accurately, as well as to signal a proximity alarm if the vehicle is approaching a hazardous distance that may cause an accident. Moreover, the researchers found that brightness and the distance of the camera affect the quality of the data processing. In this experiment, the author measured the level of accuracy and efficiency of the car distance detection system which detects the distance from the license plate of the vehicle in the front and the vehicle that follows, the system's accuracy was measured at 95 percent, which was excellent.
