Abstract

The present studies about road and road-edge detection are mainly based on laser sensor, LIDAR sensor, laser radar, frequency modulated continuous wave (FMCW) radar and machine vision. In this project, an instrument was developed for road and road-edge detection to measure road width. It was also may be used on the road line painting mobile robot. The device is based on the ultrasonic sensor. Nowadays, the process of road line painting was done manually by human. It takes many time, money and manpower. Workers also were at risk to have an accident during painting the road lines and it may be fatal. The objectives for this project are to design an instrument to measure road width and to analyse the accuracy and the reliability of the sensor for road width measurement. The project was used an ultrasonic sensor as a road region detection. The rotating of ultrasonic sensor have ranging the road region to detect the road edge. The ultrasound wave transmit to the road region reflected to the receiver. The time of flight is determined as well as the distance between the sensor and the road surface. The road surface profile was plotted and display on the computer. Several experiments were done by the instrument and the results showed the proposed method on accuracy and reliability.
