+Image recognition and matching algorithms
For digital speckle and coded markers, high-precision digital image correlation matching algorithms, marker center positioning and coding recognition algorithms have been developed to achieve accurate positioning and matching of multiple features.
+High-precision camera flexible calibration algorithm
A flexible global camera calibration method based on photogrammetry technology can complete single-camera, dual-camera, and multi-camera calibration in the range of a few millimeters to tens of meters. This method does not require the exact size of the calibration object in advance. Utilizing 10 parameters and a 2F camera lens distortion model, it can accurately calibrate optical systems such as conventional, ultra-short-throw, ultra-telephoto, and stereo microscopes.
+High-precision 3D reconstruction algorithm
A photogrammetry algorithm based on single-camera multi-perspective has been developed, which can perform accurate three-dimensional reconstruction of key points. At the same time, a full-field dense point three-dimensional reconstruction algorithm based on binocular stereo vision has been developed to realize dynamic measurement and rapid solution of full-field big data.
+Rich data post-processing algorithms
It has 18 deformation and strain calculation methods, interpolation and hole filling and data smoothing algorithms, multiple geometric element creation and distance and angle analysis functions based on the created elements, etc., combined with curve and icon display, making scientific research more efficient and convenient.
