Deformation detection via visual metrology (geodetic method) for inspection and data validity of an object has high potential in structure measurement. Visual metrology are based on close range photogrammetry i.e. V-STARS system. The V-STARS system is an enhanced (and portable) digital close range photogrammetric system for precise 3D coordinate measurement using special high-resolution digital intelligent camera (INCA), special target (high contras retro-reflective) and special software, for the automation of the entire measurement process. The typically accuracy of V-STARS is better than 10 ppm, i.e. about 0.010mm on a 1.0m object. This research focuses on the procedure and potential of deformation detection using visual metrology technique and S-transformation for geometrical analysis via displacement vector and graphic presentation. A simulation test is included to verify the practicality of the procedure.
