I have a laser grid plotted on a object. A stereocamera watches this scene (a pair of images of the same subject).

I want to detect nodes (cross points) of the laser grid in a image. Using Harris is not a good solution, because it founds all the corners not the intersection. How to find the center of the intersection?

One of my image is attached

So, if i have the skeleton... how to find the intersection there? With 'banchpoints' is not enough accurate, because there are a lot of spurity in the skeleton
