Example of angular correction
1. Detection of the amount of angular deviation (using measurement 0, 2 point search (positional
deviation measurement).
2. Performing measurement 1 to 4 (of distance and angle measurement) on an image that has been
rotated around its center by the amount of angular diviation detected in step 1.
