Edges along lines or circular segments are measured with subpixel accuracy in less than a millisecond. Combined with grayscale calibration, nonlinear grayscale distributions can also be compensated, achieving the highest precision.
By fitting ellipses or other shapes to subpixel-accurate contours computed by an edge filter, maximum precision is achieved.
The measurement model automatically extracts contour data, including from multi-channel images such as color images. Typical tasks include measuring circle diameters or geometric structures.
Disparity and distance images, as well as 3D coordinates of surfaces, can be reconstructed using various methods, including:
In addition, the software enables 3D pose estimation of circular and rectangular objects using only a single camera. By segmenting and fitting 3D primitives such as cylinders, spheres, and planes, surfaces and volumes can be measured precisely.
