# Step 1: Find and Label the Checkerboard Vertices

This step locates the vertices in the image of the checkerboard calibration plate or the dot centers in a grid-of-dots plate. It then uses the grid spacing ("tile size") information and the grid point locations to automatically label each grid point.

Inputs:

- CalibrationImage()

Outputs:

- NumPoints()

- GetUncalibratedPointX()

- GetUncalibratedPointY()

- GetUncalibratedPoint()

- GetRawCalibratedPointX()

- GetRawCalibratedPointY()

- GetRawCalibratedPoint()
