Description
Use this component to find lines in the image using Canny edge detection and Hough transform.
Diagram:
Example:
Pins
- OutputPin - The detected lines data output pin of the component.
- TransfromOutputPin - The Hough transformation matrix data pin.
Events
- OnLinesDetect - Occurs each time lines are detected.
