Infrared thermography has emerged as a promising method for inspecting tiled building exteriors, leveraging temperature variations caused by solar radiation to detect detached tiles. Traditional methods require positioning an infrared camera at high altitudes to ensure that the angle between the camera's optical axis and the vertical axis of the tile surface does not exceed 45 degrees. While drones have been employed to address this challenge, stringent regulations in urban areas often restrict their use.
This study proposes an innovative approach to exterior wall inspections using a balloon-mounted infrared camera. This method offers several advantages over drone-based systems, including the elimination of requirements for aircraft certification, pilot licenses, and other permits. Additionally, balloons operate quietly and safely, reducing operational risks and costs. The balloon-mounted system provides stable and unrestricted operation, making it particularly suitable for densely populated urban environments where drone usage is heavily regulated.
Our results demonstrate that the balloon-mounted infrared camera system is capable of maintaining the necessary angle and resolution for effective thermographic inspections, achieving a pixel density significantly exceeding regulatory standards. This approach enhances the efficiency and reliability of detecting potential detachment areas on building exteriors, providing a viable alternative to traditional methods. The findings highlight the potential of this balloon-based technique to revolutionize the field of high-rise building inspections.
