Fingertip Pose Estimation

What method should I use to do fingertip pose estimation if I cannot use checker-board.

I was reading about SLAM methods, but failed to understand how to use it to do fingertip pose estimation.

I read about FastSLAM, EKF-based SLAM and LSD-SLAM . what should I use to do pose estimation of my hand and also calculate the camera matrix.

SLAM is simultaneous localization and mapping, it has nothing to do with finger/hand tracking. Most SLAM implementations assume a static scene and humans are anything but static. Your best bet is to get 3D data either via stereo cameras or a 'depth camera' like the Kinect or an Intel offering (both are stereo with structured light, though some versions are time-of-flight). Then with both 2D and 3D information, train a detector/segmentor and then a pose estimator. The pose estimator will require synthetic data as ground truth cannot be obtained any other way (except maybe form an existing system). This is no small feat, so as a first approach, I recommend skin-color segmentation and convexity defects analysis as much can be found on this approach.
