2D calibration

Although not essential for all applications, calibrating a vision system is important if you are looking to extract data and make decisions based on measurements using real world units, such as for robot guidance.

In its simplest form, calibration converts the pixel output from a camera into real world units or complete images. Good calibration algorithms not only transform the coordinate systems, but eliminate perspective and lens distortion. For 3D calibration please refer to 3D tools.
