I'd like to detect circles in a 8bit image using the grayscale information (instead of brutally applying a threshold) in order to get sub-pixel accuracy. Does Labview do that? Did anybody write a program that does it? I'm using labview 5.0.1 and Imaq vision. thanks
The good news is that it is relatively easy to do. The bad news is that it uses a new tool in IMAQ Vision 6.
There is a tool that will locate the edges of a circle and determine the size and location of the circle. It is called a circular rake. It basically finds edges along radial lines around the circle, then determines the circle parameters.
