versatile. You can find detailed information on this in the section "Performance features of
PAT Genius object recognition (Page 76)".
• Apart from the normal functions for object recognition such as determining the object
position, angle of rotation and quality, the PAT Genius algorithm has the following
properties:
– Invariance (= insensitivity) to size scaling (selectable range)
– Very high accuracy
– Simultaneous recognition of up to 200 instances of one or more models in one step
– Simultaneous search for different models
– Important for classification tasks: Very good selectivity even with very similar objects.
• By means of comparisons with desired specifications in the form of the processing result
when saving the program, even complex presence checks can be created very quickly and
simply.
• A preview function is available in the locator steps. At all times, the preview function
provides feedback about the effects of the currently active settings.
• The very flexible parameter assignment of the result output using format tags also
provides many options for representing the object recognition results. This means that
results that are important for your application can always be transferred to the process.
