Texture of material:alumina,Surface non-reflective。
1、Characteristic of calibration board:Using High Precision Processing Technology,Low coefficient of thermal expansion,High-precision(±0.01mm )、All sizes can be customized。2、Scope of application:Research institutes or special high-precision calibration tools in the field of vision,Three-dimensional image measurement、Three-dimensional Reverse Engineering、stereo matching、Three-dimensional reconstruction, etc.,Data of camera calibration results are obtained mainly through calibration software。
3、Effect:To correct lens distortion、Determining Conversion Relations between Physical Sizes and Pixels,And determine the relationship between the three-dimensional geometric position of a point on the surface of a space object and its corresponding points in the image.,Geometric model of camera imaging needs to be established,For accuracy measurement,The distortion of lens itself is unavoidable,Calibration is used to improve the application performance of high precision measurement and detection.,To achieve satisfactory accuracy。
4、Use:Most software supports solid dots or squares as markers。High Precision Camera Calibration,Most of them use feature points as reference points.,Accurate extraction of center position by graph fitting。Elimination of centroid caused by projection by known calibration template parameters。
