摘要： An improvement of measuring geometry parameters of a geometry object from an image with a reference object whose thickness can not be ignored. A hidden point on the plane with which geometry object contacts is computed from visible points. The computed hidden point combined with other points in the same plane is used to compute a homography matrix between a known size shape and its projection in the image. With the computed homography matrix and enough valid points in the image, the geometry parameters of the geometry object are determined. With the geometry parameters of the geometry objects, useful information can be calculated from.
