hi i want to develop a facial motion capture system. i want to get 3d position of markers that is mounted on face of actor. i want to know can i get real 3d position with two camera and is there any library that capture 3d position of all markers?

Since you have the points, just calibrate both cameras and then look for stereo correspondance of markers. That will yield 3d positions!

is there any library that get two camera output and give us 3d position of markers?

and another question is that witch camera types i can use?

Please stick to comments as long as no solution has been suggested. As to your questions, OpenCV can do that, look at the calib3d module which is explicitly for calibrating a stereo setup and retrieving 3D points. The position of the markers will play a big role in the stereo matching. As to the camera types, basically any decent resolution camera will do the trick.
