Detection of vanishing points with matlab

Bonjour,

I have a problem of detection of vanishing points (les points de fuites) in image , in fact i have to extract planes in monocular image using matlab and all the algorithms that i found it are based on detection of lines and vanishing points.
Please who have an idea or code of vanishing points detection help me
I have to finish my project as soon as possible and i can't find a solution for this issue
I'm waiting for your answers and i hope have a solution.
Regards
