Vibration Measurement of a Metal Sheet Using Single-Camera Digital Image Correlation with Projection Components
Shock and Vibration
Digital image correlation has emerged as a popular method for the dynamic performance measurement of metallic and polymer sheets, owing to the benefits of being a noncontact, full-field, and high-precision method. Two or more high-speed cameras are required for full-field vibration measurements with three-dimensional digital image correlation, which is generally costly. Perpendicular view to the specimen surface is conventional in two-dimensional digital image correlation, and the out-of-planedoi:10.1155/2022/1098337 fatcat:fi5mp3fd2vajlbhdxe7fzr4z3e
