[50x50mm]

Material: Aluminum Oxide, Non Reflective Surface Optical Float Glass
Main features:
High precision processing technology, low coefficient of thermal expansion, 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 obtain the data of camera calibration results through calibration software.
Function:
For correcting the lens distortion, determine the physical size and conversion ratio between pixels and determine the space objects at a certain point on the surface of the three-dimensional geometry and the interrelation between the corresponding points in the image to determine the geometry model of camera imaging, for precision measurements is a distortion of the lens itself inevitable. Calibration is used to improve the performance of the application of high-precision measurements and tests to achieve satisfactory precision
Intended use:
Most programs support filled points or squares as landmarks. In the process of high-precision camera calibration, feature points are usually used as reference points to accurately extract the center position through graphfitting. The center of gravity caused by the projection is eliminated by known calibration template parameters.
