Many historical structures in Pennsylvania have lost their valuable surface texture and even structural integrity. Restoring those historical structures are important to the local culture, tourism, and economy. Traditional photography, ultrasound, Eddy Current and Lidar imaging methods are not able to provide enough details in large scale and in high speed. In this project, we develop a reconfigurable 3D surface texture scanning and modeling technology for surface inspection and reconstruction. The system consists of affordable hardware such as digital cameras, a data projector, and a laptop. The software includes robust mobile self-calibration algorithm, texture characterization, template matching, and performance optimization algorithms. The Pennsylvania corporate partners include Old St. Luke Church. The CMU faculty collaborators include faculty members from Robotics, ECE, Architecture, and ACRC.
