Epson 5 CameraY2 Result

CameraY2 Result

CameraY2 Result

Applies To

Vision Objects: Line

Description

Returns the ending point position (Y2) of a Line object in Camera coordinates.

Usage

VGet Sequence.Object.CameraY2, var

Sequence Name of a sequence or string variable containing a sequence name.

Object Name of an object or string variable containing an object name. The object must exist in the

specified sequence.

var Real variable that will contain the value of the result.

Values

The value returned for the CameraY2 result depends upon the calibration used for the camera. Values are

always returned in millimeters.

Remarks

Every line must have a starting point and ending point. The CameraY1 and CameraY2 results represent the

Y coordinate position starting (X1,Y1) and endpoints (X2,Y2) of the specified Line object. Since Line

object starting and endpoints can be assigned to other vision objects, the (CameraX1, CameraY1) and

(CameraX2, CameraY2) coordinate pairs can actually be Camera coordinate positions which match the

CameraX and CameraY results for other vision objects. (In other words if a Line object's starting point is

defined by a Correlation object, then the (CameraX, CameraY) results from the Correlation object will

match the (CameraX1, CameraY1) results for the Line object.)

It should be noted that the CameraY2 result can only be calculated for vision sequences which have been

associated with a calibration. If no calibration has been assigned to the vision sequence then if VGet is

used to retrieve the CameraY2 result, an error will occur.
