MultiDIC contains novel algorithms to automatically merge meshes from multiple stereo-pairs, and to compute and visualize 3D shape and full-field motion, deformation, and strain. MultiDIC integrates robust two-dimensional subset-based DIC software with specially tailored calibration procedures, to reconstruct the dynamic behavior of surfaces from multiple stereo-pairs. To address these limitations, we present MultiDIC, an open-source MATLAB toolbox, featuring the first 3D-DIC software specifically dedicated to multi-view setups. While various commercial and academic 3D-DIC software exist, the field lacks 3D-DIC packages which offer straightforward calibration and data-merging solutions for multi-view analysis, which is particularly desirable in biomedical applications. 3D-DIC can be used to extract shape and full-field displacements and strains with high resolution, at various length scales. Three-dimensional Digital Image Correlation (3D-DIC) is a non-contact optical-numerical technique for evaluating the dynamic mechanical behavior at the surface of structures and materials, including biological tissues.

The reason behind this is due to - PLUS setting that does not use Reference. Thank you.Ī) Only Reference value for NDI, Slicer and Unity is the sameī) All other sensors for both Slicer and Unity which share the same value contradicts with NDI. It is a great help in getting us a useful result. If I am multiplying them with IJKToRAS - none of the values are the same in all 3 Apps. I am getting different values in Unity, compare to the value from NDI Track App.Īnd, the value I am getting from NDI Track App is the same for Slicer and Unity.ĭoes it mean that I need to set the Needle origin in Slicer or can I set this in PLUS server setting? so that I get same values for Needle coordinates in NDI Track, Slicer and Unity?įYI - The reference coordinate is correct and similar for all three - NDI Track, Slicer and Unity (if I am using the matrix and not the IJKToRAS) It looks like the steps for conversion is not complete there. = LPS_to_RAS * inv( fromParent_LPS ) * RAS_to_LPS IJKToRAS.SetRow(3, new Vector4(0.0f, 0.0f, 0.0f, 1.0f)) Ĭomparing to the steps that you described above Matrix.SetRow(2, new Vector4(m, m, m, m / scaleMultiplier)) Matrix.SetRow(1, new Vector4(m, m, m, m / scaleMultiplier)) Matrix.SetRow(0, new Vector4(m, m, m, m / scaleMultiplier)) Refering to Unity Code (OpenIGTLinkConnect.cs) taken from this Github ( OpenIGTLink-Unity/OpenIGTLink-Unity/Assets/Scripts at master
