This conference contribution introduces and validates a laboratory-scale measurement method employing photogrammetry techniques. With the rapid advancement of computer vision technology, it is possible to improve the limitations of traditional wave gauges and better describe temporal and spatial wave field variations using such techniques. This method effectively reconstructs water surface variations using data from webcam recordings. It captures wave characteristics at a single location, akin to traditional wave gauges, and can also reconstruct the 3D free water surface, revealing wave fields over time and space. With appropriate temporal and spatial resolution, capturing more detailed variations in the wave field is possible. The wave height extracted from the 3D free water surface reconstruction (6.28 cm) also compares with that measured by the wave gauge (6.24 cm). This approach provides an effective supplementary tool for measuring wave characteristics, offering advantages over traditional wave gauges.
