This seems to find the intersectionpn that image:

run("8-bit");
run("Invert");
run("Minimum...", "radius=4");
run("Gaussian Blur...", "sigma=6");
run("Find Maxima...", "noise=10 output=[Point Selection]");
getSelectionCoordinates(x,y);
print(x[0],y[0]);

You might have to adjust some of parameters above (radius and sigma) depending
if the line thickness is always the same.
Perhaps converting to 32-bit instead of 8-bit is better, not sure.

Hope it helps.
Cheers

Gabriel
