4.3.3. Edit a Template
The purpose of editing a template is to extract features of shooting points. Thus, it is
convenient to find the position of the feature points in the picture according to the
extracted features.
When enditing a template, please ensure:
• The number of extracted feature points is enough.
• The workpiece is not tilted, because it is not allowed to pick the feature points
while the feature points are tilted.
