I have done that. I have captured images from HTC Smartphone. I have designed CHECKER BOARD and have taken pictures of it from my phone. I then used opencv to calibrate my camera. I have got the fx, fy, cx and cy parameters. I also tried MATLAB calibration toolbox. Thanks a lot to all for your guidance.

You normally need focal length to do matching between 2d images and 3D models. Focal length makes up your camera matrix which u need to compute the pose via RANSAC. If you get good pose between your 2D image and 3D model then you say you have found the match. I kept my query really simple so everyone can understand.
