Study on Pole in the Application of Three-Dimensional Reconstruction

Abstract:

Making use of the three-dimensional reconstruction that poles features do to the two elements of the space and the quadric curve,we can make the polar lines of the image pairs.The polar lines in one of the features points meet and form the pole.According to the speciality the pole has in the optical center line of the CCD-camera and making use of the invariance of the rate of change of the theorem of the sequence in the projective transformation,we can find the corresponding matching points.According to the characteristics of their orders,their intersections form space objects.At last,accordiong to it,we can get the correct parameters of the space objects.
