Example 1

An example of a good image is shown to the right. The ruler is close to the object, it is in the same level and the image is taken in a perpendicular angle.


  1. Lay the object (in this case a leaf) flat on an even surface, like a table
  2. Place the calibration object (in this case a ruler) next to the object
  3. Acquire the image in a perpendicular angle
