Non-contact distortion and displacement measurement Digital Image Correlation method sDIC system
sDIC
By measuring distortion and displacement through image measurement, it is possible to measure coordinates, displacement, velocity, distortion, shape, and deformation.
sDIC is a non-contact strain measurement software that analyzes the deformation and strain distribution of the measurement target using Digital Image Correlation (DIC). The Digital Image Correlation method involves applying a random pattern called a speckle pattern to the surface of the measurement target and comparing images before and after deformation to analyze the extent of deformation. It can detect not only the amount of deformation but also the direction of deformation. By performing sub-pixel interpolation, it achieves high-precision measurement with a displacement resolution of 1/10 to 1/100 of a pixel, which has garnered attention in recent years.

basic information
Digital Image Correlation (DIC) is a method that involves applying a random pattern called a speckle pattern to the surface of the measurement target, and by analyzing images before and after deformation, it measures strain and displacement, visualizing the deformation. It is also referred to as DIC, which is an abbreviation for Digital Image Correlation. Unlike strain gauges, it analyzes strain and displacement through image analysis, allowing for the visualization of surface and three-dimensional strain in a non-contact manner. Seika Digital Image has established a development system for the strain analysis software sDIC and specializes in proposing systems tailored to customer needs. There is 'sDIC 2D,' which uses a single camera for two-dimensional (xy) analysis, and 'sDIC 3D,' which uses two cameras for three-dimensional (xyz) analysis, including depth direction. Additionally, we offer standalone 'sDIC software' for those who already have an image acquisition environment, as well as a complete 'sDIC system' that includes cameras, lenses, fixtures, lighting, and analysis PCs.
