Anleitung Zusammenfassung
When teaching an object which has the CenterPointObject set to something other than Screen, the vision object defined as CenterPointObject is executed first and the resulting position (PixelX and PixelY) is used to position the object before it is taught. In order for the current object to be found in the future also requires that the vision object defined as the CenterPointObject is found so that the center of the current object can be based on the PixelX and PixelY positions for that object. See Also Blob Object, CenterX Property, CenterY Property, Correlation Object, Geometric Object, Object Tab, Polar Object CenterX Property Applies To Vision Objects: Polar Description Specifies the X Coordinate position to be used as the center point for the Polar object. Usage VGet Sequence.Object.CenterX, var VSet Sequence.Object.CenterX, value 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 property. value Real expression for the new value of the property. Values Real number from 0 – (video width in pixels – 1). However, we must take into account the value of the Radius property for the Polar object since the center of the Polar object cannot be at the edge of the Camera's field of view. Therefore, the actual range is: (0 + Radius) - (Max Camera X Resolution – Radius – 1) For example, an image resolution of (640x480) and a 16 pixel radius gives a range of 16 - 623. Default: X coordinate screen position of the center of the Polar object Remarks This property is filled in automatically when the CenterPointObject property for a Polar object is set to another vision object. However, if the CenterPointObject property for a Polar object is set to Screen, then the user may set the CenterX property to position the Polar object. The user may also set the CenterPointObject property for a Polar object automatically by physically dragging the Polar object to a new position on the screen. When this drag operation is done, the CenterX property is automatically updated with the new CenterX position of the Polar object. See Also CenterY Property, CenterPoint Property, Object Tab, Polar Object CenterY Property Applies To Vision Objects: Polar Description Specifies the Y Coordinate position to be used as the center point for the Polar object. Usage VGet Sequence.Object.CenterY, var VSet Sequence.Object.CenterY, value 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 property. value Real expression for the new value of the property. Values Real number from 1 – (video width in pixels – 1). However, we must take into account the value of the Radius property for the Polar object since the center of the Polar object cannot be at the edge of the Camera's field of view. Therefore, the actual range is: (0 + Radius) - (Max Camera Y Resolution – Radius – 1) For example, an image resolution of 640x480 and a 16 pixel radius gives a range of 16 - 463. Default: Y coordinate Screen Position of the center of the Polar object Remarks This property is filled in automatically when the CenterPointObject property for a Polar object is set to another vision object. However, if the CenterPointObject property for a Polar object is set to Screen, then the user may set the CenterY property to position the Polar object. The user may also set the CenterPointObject property for a Polar object automatically by physically dragging the Polar object to a new position on the screen. When this drag operation is done, the CenterY property is automatically updated with the new CenterY position of the Polar object.

Usage VGet Sequence.Object.Compactness [(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 integer result number from 1 to the NumberToFind property. If omitted, the result number is the CurrentResult Values Minimum value is 1.0. Remarks Compactness is a measure of how close all particles in a blob are from one another. It is derived from the perimeter and area. A circular blob is most compact and is defined to have a compactness measure of 1.0 (the minimum). More convoluted shapes have larger values.
