signature

The signature friend class holds the Vision Sensor Signatures. signature objects are used to make code Class objects and used directly with the vision class. Up to seven Signatures can be stored at once.

A Signature is created by using the following constructor:

The signature constructor uses nine parameters:

Parameter	Description
index	The signature object’s index, from 1 - 7. Note: Creating two signature objects with the same index number will cause the second created object to override the first.
uMin	The value from uMin in the Vision Utility.
uMax	The value from uMax in the Vision Utility.
uMean	The value from uMean in the Vision Utility.
vMin	The value from vMin in the Vision Utility.
vMax	The value from vMax in the Vision Utility.
vMean	The value from vMean in the Vision Utility.
rgb	The value from rgb in the Vision Utility.
type	The value from type in the Vision Utility.

In order to create a Signature, go to the Vision Utility and configure a Signature. Once a Signature is configured, copy the parameter values from the Configuration window.

// Create a new Signature "darkBlue" with the signature class.
vision::signature darkBlue = vision::signature(1, -3911, -3435, -3673,10879, 11421, 11150,2.5, 0);
