This study evaluates the feasibility and accuracy of using smartphones for road crack detection through open-source and commercial image analysis tools. High-resolution images were captured with Galaxy and iPhone smartphones, and their accuracy was enhanced using ground control points (GCPs) determined by Network RTK surveying. The study utilized Reality Capture and Pix4DMatic for image analysis, comparing their results with actual measurements. Pix4DMatic effectively converted smartphone images into precise 3D models, detecting even small cracks with minimal error. The findings indicate that smartphones offer a cost-effective and efficient solution for road maintenance, providing high precision and convenience without the need for frequent site visits. Future research should validate this method under various conditions and enhance data collection and analysis automation.
