Correction of lens distortion However, it should be note that the lens distortion is not considered for the computed 3D coordinates of the temporal points, nevertheless lens distortion influences 3D coordinate of the temporal control points. In order to revise lens distortion, epipolar geometry is adopted in this paper. Epipolar line for a temporal control point on the left image is obtained on the center image, similarly epipolar line for the same point on the right image is obtained on the center image. The correction of lens distortion is performed using these epipolar lines since two epipolar lines should be intersect at the same point on the center image if there are no lens distortion. In this method, the lens distortion was corrected by calculating the orientation parameters to minimize the difference between intersection point (p?) and interesting point (p;) at the center image by following equations.

EXPERIMENTATION In order to evaluate the calibration method which is proposed in this paper, triplet images were taken using amateur digital camera CP-900Z(EPSON). Figure 4 shows appearance of the CP-900Z, and Table 1 shows the specifications. Table 2 shows imaging conditions and Figure .5(a)-(c) shows the triplet images. 17 circular points are temporal control points and check points. 3D coordinate for these points were measured by the total station MET2NV(SOKKIA MET2NV, distance accuracy — Imm, angle accuracy 3 2^" ), and image coordinate for the points are given as the center of area gravity by image processing. Table 3 shows the exterior orientation parameters
