Use a Find Line tool to configure a series of Caliper tools over a specified region of an image to locate multiple edge points and return the line that best fits those input points while generating the highest score based on a scoring function you choose and the smallest root mean square error (RMSError).
The Find Line 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 Line 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 Line tool after it fits a line to the found edge points.
- The LastRun.RegionData_Caliper<X>, where <X> represents a caliper number.
