• How does Digital Image Correlation address the challenges of complex lighting?

  Complex lighting is a critical factor—one that cannot be overlooked—affecting the measurement accuracy of Digital Image Correlation (DIC). To obtain highly accurate and reliable DIC measurement results, lighting control must be regarded as a core component of equal importance to system calibration and speckle pattern preparation. By meticulously designing active, uniform illumination, strictly controlling the testing environment, optimizing camera settings, and ensuring high-quality speckle patterns—supplemented by appropriate image preprocessing and the selection of robust algorithms—the accuracy and reliability of DIC measurements can be maximized.

• The Impact of Complex Lighting on the Measurement Accuracy of Digital Image Correlation?

  Acquiring high-quality, stable speckle images serves as the cornerstone for ensuring the accuracy and reliability of DIC measurements; however, complex lighting conditions often emerge as one of the primary factors that degrade image quality and introduce measurement errors. This paper primarily investigates the specific mechanisms through which complex lighting impacts DIC measurement accuracy, and proposes practical strategies to assist users in overcoming these "lighting" challenges, thereby enabling the acquisition of more reliable DIC measurement data.

• What are the application advantages of a 2D-DIC measurement system in specific scenarios?

  2D-DIC measurement systems offer significantly reduced costs, rapid setup and calibration, streamlined data processing, and simplified operation; they demonstrate exceptional practical value in specific scenarios involving deformation measurement strictly within a plane—particularly where out-of-plane displacement (in the Z-direction) is minimal or negligible.
