3d Dic A General Experimental Setup B Cameras And Lenses The general 3d dic setup is shown in figure 2 a, (only basic dic principles are presented in this chapter without going into the details of 3d dic and differences compared to 2d dic, which can be. Low speed cameras system for 3d dic vibration measurements in the khz range. a stereo camera 3d dic system for full field vibration measurements is presented. the optical setup is based on two low frame rate cameras and a multimedia projector. a down sampling approach is used to overcome the nyquist shannon theorem limitation.
3d Dic A General Experimental Setup B Cameras And Lenses Metrics. stereo digital image correlation technique (stereo dic or 3d dic) has been widely used in three dimensional (3d) shape and deformation measurement due to its high accuracy and flexibility. A flowchart of the proposed multi camera 3d dic measurement method is shown in fig. 1 pared with a common 3d dic, the main challenge of this method is to unify the measurement results of multiple sets of 3d dic systems from the local coordinate systems to the global coordinate system, that is, to calculate the extrinsic parameters between systems. Abstract. the 3d digital image correlation (dic) is a very popular method for 3d shape and deformation measurements in the optics and mechanics fields. in general, the 3d dic technique requires two calibrated cameras to simultaneously capture images of object from two different views. in practice, this can be challenging for fast or high speed. The image of the cylindrical specimen captured by the single camera 3d dic system based on the fb is shown in fig. 5 (b). in contrast to the regular 3d dic method, each captured image was split into two sub images, with each sub image still having an image resolution of 1320 × 1421 pixels. the actual fiber resolution is 500 × 500 optical.
