[50x50mm]

Material: aluminum oxide, non-reflective surface. Optical float glass.
Main features:
High precision processing technology, low thermal expansion coefficient, high precision (±0.01mm).
High-precision calibration tool for the field of view
Three-dimensional image measurement, three-dimensional reverse engineering, three-dimensional matching, three-dimensional reconstruction, etc. mainly receive the data of camera calibration results through calibration software.
Function:
For the correction of lens distortion, determine the physical size and the conversion relationship between pixels and determine the space objects at a certain point on the surface of the three-dimensional geometry and the interaction between the corresponding points in the picture to set the geometry model of the camera dgebung, for Precision measurements are a distortion of the lens itself inevitable. The calibration is used to improve the performance of applying high-precision measurements and tests to achieve satisfactory precision
Use:
Most programs support filled points or squares as orientation points. In the process of high-precision camera calibration, feature points are usually used as reference points to accurately extract the centre position through graph-fitting. The centre of gravity caused by the projection is eliminated by known calibration template parameters.
