Use a Find Circle tool to configure a series of Caliper tools over a specified circular region of an image to locate multiple edge points, supply these edge points to an underlying Fit Circle tool, and return the circle that best fits those input points while generating the smallest root mean square error (RMSError).
The Find Circle edit control allows you to specify the region of the image analyzed, control the number of Calipers used, and view vision tool results.
See the topic Control Reference for a description of the buttons along the top of the edit control
A Find Circle tool edit control supports the following image buffers:
- The Current.InputImage buffer contains the current image and the set of calipers that will search for edges.
- The LastRun.InputImage buffer contains the results of the Find Circle tool after it fits a line to the found edge points.
- The LastRun.RegionData_Caliper<X>, where <X> represents a caliper number.
