# Acquire Calibration Image

To use a Checkerboard Calibration tool you must acquire an image of a calibration plate and provide the spacing of the grid points on the plate in physical units. The tool locates the vertex points in the plate and computes the best-fit 2D transformation between the vertex points in the calibration image and the supplied physical units, storing the calibration data.

Your application must call the Calibrate method to generate the calibrated coordinate space.
