Extract crosshair in a image for edge detection

Hello,

 

I'm trying to extract the crosshair in the attached image in order to detect the edges of it. An alternative would be to remove the green cross in the picture.

Does anyone got an idea how i could do this with Vision?

 

Thank you!

 

Best Regards

I could solve the problem with the Vision Operator-VIs. Especially with the IMAQ Compare VI comparing to a constant.

Extract the grren plane from your image

Then run an edge tool top to bottom and then one bottom to top. Average the two lines

Repeat this but now do the horizontal axis

Intersect of the two lines and you have the coordinates of the centrepoint
