Hi, I am solving a similar problem. Did you find the coordinates of the sphere in the STL image?

Have a few spheres? Is there a distance between them?

x1 = X(X<a & Y>b);
y1 = Y(X<a & Y>b);
x2 = X(X>a);
y2 = Y(X>a);
x1 = X(X<a & Y<b);
y1 = Y(X<a & Y<b);

Hi, yes I did.

First the user select the point in the STL image (ginput), then I selected the area near the point through a function called findNeighborsInRadius (the name is pretty self explanatory) and finally I used the function pcfitsphere.
