CameraY1 Result
Applies To
Vision Objects: BoxFinder, Line, LineFinder
Description
Line, LineFinder: Returns the starting point position Y coordinate (Y1) of a Line object in Camera coordinates.
BoxFinder: Returns the Y (Y1) coordinate position for corner points of rectangles detected in a camera coordinate system.
Usage
VGet Sequence.Object.CameraY1[(result)], 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.
- result
- Optional result number. If omitted, the result number is the CurrentResult. Used for objects that return multiple results.
Values
Real number in millimeters.
Remarks
For Line, LineFinder
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.)
For BoxFinder
The camera coordinates for the four corners of a rectangle can be retrieved as Camera X1, 2, 3, 4 results and Camera Y1, 2, 3, 4 results. CameraY1 is used to retrieve the Y coordinate for the Corner1 point shown in the diagram below.
The CameraY1 result can be calculated only when valid calibration data is set to the Calibration property of the vision sequence. If the calibration has not been completed or the Calibration property has not been set, the CameraY1 result will be an error.
