AB  - To reduce the uncertainty region of a three-dimensional (3D) position, a 
      four-camera 3D digital image correlation (3D-DIC) system was built by 
      orthogonally arranging two sets of two-camera DIC systems. The theoretical model 
      proposed herein revealed the relationship between 3D coordinates and system 
      parameters and the propagation of the matching error to the position error. 
      Numerical simulation and experiment were conducted to verify the theory. The 
      simulation and experimental results indicated that the 3D position error of the 
      four-camera system was smaller than that of the two-camera DIC system. The 
      present contribution proves the feasibility of using four-camera DIC systems to 
      improve measurement accuracy.
