Autonomous Robot for Crack Detection and Mapping for Bridge Surface

Abstract

ABSTRACT:Aim of this project is to inspect and detect the cracks on the bridge surface using of autonomous robot which is equipped with android phone having high resolution camera used to transmit the images wirelessly to the laptop through local host WAMP-Server. The main purpose of this research is to create 2-dimension crack map of the inspected area. For crack detection and Mapping, MATLAB tool is utilized. Image processing is being used as the technique to detect cracks. Edge detection algorithm is used in image processing technique where different preprocessing of image is done and morphological operations are performed to detect cracks. We have used prewitt operator for edge detection along with median filter. We can control motion of mobile robot via control panel is developed in MATLAB. Prior to this Android APK is developed and installed on phone which capture images and sends via WAMP-Server to the laptop where images are received and processed in MATLAB. Finally we have trying to create two dimensional map of crack detected image which will be very helpful to engineers who inspect and points cracks on bridge manually, locating position of crack.
