Abstract

Indian roads are full of potholes and during monsoon season the potholes are lled with water. This makes it dicult for the driver to drive upon the potholed roads. So its crucial to detect water-lled potholes. Dry pothole detection has already been done using sound waves. Detection of water-lled potholes is harder. The sound waves from the ultrasonic sensor will not penetrate the water surface due to impedance mismatch of air and water. So to detect the water-lled potholes a laser beam based system is used. The frequency of the laser beam which can detect water-lled potholes need to be used. The wavelength in the range of 400 nm to 450 nm which has less absorption in water is used. This range is blue light which is least attenuated in water. So a multimodal sensing system is designed to detect both dry and water-lled potholes.
