Chovan, C., Mengiste, B., Chen, X., Yang, L. et al., "Improving Material Property Measurement by Using Multi-Camera Digital Image Correlation," SAE Technical Paper 2013-01-1428, 2013, doi:10.4271/2013-01-1428.
In this work, a multi-camera Digital Image Correlation (DIC) system is applied to measure the material properties of aluminum (5754) specimens. Such tests are usually done using 2D (one-camera) or 3D (two-camera) DIC systems. A multi-camera DIC system includes three or more cameras and inherits all the advantages of a conventional 3D DIC system (with two cameras) such as, full-field measurement, high accuracy and high speed. In addition, this system further improves the measured results by including redundant data. In this work, we will show the potential of this system to measure a variety of material properties at one time.
