Radius Property
Applies To
Vision Objects: Polar
Description
Defines the radius for a Polar object. See diagram below.
Radius
Usage
VGet Sequence.Object.Radius, 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
Integer variable that will contain the value of the property.
Values
The radius in pixels
Default: 50
Remarks
It is important to remember that the Polar object is used to process images that are circular in nature. The
Radius property defines the size of the circle used for the Polar object. This means that the Radius property
along with the Thickness property defines the size of the Search Window for the Polar object.
The size required for a Polar object Search very much depends upon what the Polar object is being used for.
For example, if the Polar object is being used to Inspect Gear Teeth then the Polar object should be made
just a little larger than the Gear to be inspected. However, if the Polar object is used just to find an angular
position of a specific part of an image, then the Polar object may be smaller in size. Keep in mind that the
smaller the Polar object search window, the faster the execution time for the Polar search.
