XTOP-DK Series

3D measurement SDK software

DIC digital speckle, DIC full-field strain measurement system, DIC measurement system
An efficient SDK toolset designed for photogrammetry and 3D reconstruction
XTOP-DK is a highly efficient SDK toolset designed for photogrammetry and 3D reconstruction. It provides powerful camera control and calibration, 3D point cloud reconstruction, deformation calculation, and data analysis capabilities for scientific research, engineering, and industrial applications. Its core algorithm combines camera control with digital image correlation and stereo vision techniques to track and reconstruct speckle patterns or markers on an object's surface, enabling dynamic measurement of full-field 3D coordinates, displacement, and strain on an object's surface during deformation.
Modular design

Modular design

The algorithm library adopts a modular design, including modules such as data, camera, reconstruction, calculation and analysis, covering the complete chain from basic data structures to advanced computing functions, forming a full-link closed loop of "acquisition-reconstruction-analysis-output". Each module is decoupled through a C++ standardized interface, supports independent calling or collaborative work, and provides multi-threaded acceleration capabilities, taking into account the real-time requirements of industrial inspection and high-precision expansion of scientific research scenarios. Users can flexibly cut or customize the function chain based on business needs, and achieve one-stop efficient analysis from camera image acquisition to image processing, from point cloud reconstruction to post-processing analysis.
Advantages and features of XTOP-DK software
XTOP-DK software uses advanced algorithms and modular design to help users quickly and accurately reconstruct 2D images into 3D point clouds. It also supports advanced functions such as point cloud processing, deformation measurement, and material analysis.
