11.1. Method of Image Matching
11.1.1. Method 1– Geometric Feature Matching
l System saves the pattern and features of the image and inspects the image
according to the features. [Missing] is inspecting with this algorithm and you can
select this algorithm to do image matching for [Warp].
11.1.2. Method 2– Normalize Correlation Matching
l System learns gray level and feature of the image then finds the best matching
object in the search range when inspecting. [Lead] is inspecting with this
algorithm and you can select this algorithm to do image matching for [Warp].
