Abstract

The present teaching relates to method, system, medium, and implementations for estimating 3D coordinate of a 3D virtual model. Two pairs of feature points are obtained. Each of the pairs includes a respective 2D feature point on an organ observed in a 2D image, acquired during a medical procedure, and a respective corresponding 3D feature point from a 3D virtual model, constructed for the organ prior to the procedure based on a plurality of images of the organ. The first and the second 3D feature points have different depths. A 3D coordinate of a 3D feature point is determined based on the pairs of feature points so that a projection of the 3D virtual model from the 3D coordinate substantially matches the organ observed in the 2D image.
