Abstract: In this paper, ultrasonic system approach to obstacle detection and edge detection for industrial and rescue operations has been presented. The developed system consists of tough sonic sensor configure with personal computer for monitoring. First, the mathematical model has been presented for the object detection system. Then the numerical simulation has been performed using Matlab platform. The experiments have been conducted using ultrasonic frequency. The curtain, paper and bamboo sheet have been considered as a media during experiments. The presented system is highly accurate for object detection and edge detection behind the obstacle.


Keywords: Ultrasonic, Surveillance system, Object detection, Edge detection
