Abstract

The aging and reduction in quality or strength of some structures such as buildings is a bigger concern. Hence, regular inspections in order to preserve the structures are really necessary. Consequently, there is an increase in cost especially in terms of safety due to the difficulty to access. Drones would be the most suitable tool replace the existing method of visual inspection, which provide several advantages. This study aims to apply technology of drones for visual inspection without consuming a lot of cost. In order to achieve the aim of this study, several objectives have been identified and there are to study and explore the drone technology in maintenance for inspection, improve the current inspection method using drone by adding image processing techniques and study on the defects found during inspection and analyze them through image processing techniques. This study starts with carrying out inspection using a drone then if there any failures such as corrosion and cracks, a further investigation and analysis will be performed on MATLAB. The accuracy of the technique used to find the length of crack is found to be 73% and 27% error from the original length measured. The results obtained and recommendations are discussed and suggested at the end of this report.
