IMAQ Setup Learn Pattern 2 VI

Owning Palette: Searching and MatchingInstalled With: NI Vision Development Module

Sets parameters used during the learning phase. Execute this VI before the IMAQ Learn Pattern 2 VI.

Examples

IMAQ Setup Learn Pattern 2

Learn Mode specifies the invariance mode to use when learning the template pattern. Choose from the following values:

All (0)

(Default) Extracts template information for shift- and rotation-invariant matching.

Shift Information (1)

Extracts information for shift-invariant matching.

Rotation Information (2)

Extracts information for rotation-invariant matching.

error in (no error) describes the error status before this VI or function runs. The default is no error. If an error occurred before this VI or function runs, the VI or function passes the error in value to error out. This VI or function runs normally only if no error occurred before this VI or function runs. If an error occurs while this VI or function runs, it runs normally and sets its own error status in error out. Use the Simple Error Handler or General Error Handler VIs to display the description of the error code. Use error in and error out to check errors and to specify execution order by wiring error out from one node to error in of the next node.

status is TRUE (X) if an error occurred before this VI or function ran or FALSE (checkmark) to indicate a warning or that no error occurred before this VI or function ran. The default is FALSE.

code is the error or warning code. If status is TRUE, code is a nonzero error code. If status is FALSE, code is 0 or a warning code.

cstr.gif

source describes the origin of the error or warning and is, in most cases, the name of the VI or function that produced the error or warning. The default is an empty string.

Learn Pattern Setup Data is a string that contains information about the setup parameters selected for the learning phase. Connect this output to the IMAQ Learn Pattern 2 VI or to the IMAQ Advanced Setup Learn Pattern 2 VI.

error out contains error information. If error in indicates that an error occurred before this VI or function ran, error out contains the same error information. Otherwise, it describes the error status that this VI or function produces. Right-click the error out indicator on the front panel and select Explain Error from the shortcut menu for more information about the error.

status is TRUE (X) if an error occurred or FALSE (checkmark) to indicate a warning or that no error occurred.

code is the error or warning code. If status is TRUE, code is a nonzero error code. If status is FALSE, code is 0 or a warning code.

source describes the origin of the error or warning and is, in most cases, the name of the VI or function that produced the error or warning. The default is an empty string.
