Abstract: The irregular arch bridge is increasingly favored by designers for its aesthetic appeal. However, traditional displacement measurement methods fail to meet the high-precision, high-frequency requirements for health monitoring of such Irregular arch bridge structures. Therefore, based on the Echeng Bridge in Huizhou City, a study proposes a close-range photogrammetry system using ellipse fitting and inverse perspective transformation principles. This system effectively eliminates displacement errors caused by shooting angles and improves measurement accuracy. Experimental results demonstrate that compared to traditional total station measurement methods, both methods yield highly consistent results with measurement accuracy reaching millimeter-level requirements. The study analyzes the feasibility and measurement accuracy of applying this visual measurement system to the EchengBridge, providing a theoretical basis for similar irregular arch bridges.
