The four brick chimneys at Kamotsuru Sake Brewing are regional sake-brewing symbols recently designated as a registered cultural structure. More than 100 years old, these chimneys have deteriorated and present structural safety issues. To ensure structural integrity, prevent collapse, and establish preservation policies, Nagoya City University needed to ascertain the current conditions of the brick chimneys and evaluate seismic performance. They needed a comprehensive reality modeling application to generate accurate 3D meshes.
Nagoya City University imported hundreds of drone-captured images and ground photography into ContextCapture to create a reality model of the relevant area, reducing labor hours and costs, eliminating the need to separately model the existing buildings. Using the model provided highly accurate digital site information, enabling them to perform vibration experiments and structural analysis to develop a preservation plan. The reality mesh also allows them to map the location and degree of points of deterioration to be able to compare with current conditions
in the future.
