1. process of image registration comprises:

  • Extract two dimensional character collection (36) from two dimensional image (30);

    Extract three-dimensional feature collection (38) from 3-D view (32);

    Use perspective geometry to project into two-dimensional projection'"'"'s feature set (44) on the described three-dimensional feature collection mathematics;

    Described two dimensional character collection and described two-dimensional projection feature set are carried out the registration first time;

    AndThe parameter that use was derived the registration from the described first time is carried out the registration second time with the mathematical projection of described two dimensional image and described 3-D view.
