However, these procedures can not apply for all necessary lines due to fragment or multiple. Therefore, the unmatched lines were corrected using epipolar matching. The epipolar matching was performed using epipolar lines for the first and last image. In order to estimate epipolar lines, relative orientation was performed by coplanarity condition using the first and last image. The both ends for the each matched lines were used as pass points, and the orientation int of parameters (9j, Kj, €», 9», K;) were determined. After the orientation, geometric correction of the first and last image was (b) Probabilistic relaxation en performed using the orientation parameters. Consequently, ded to epipolar lines were estimated. of the Furthermore, in order to perform stereo matching using these e third epipolar lines efficiently, stereo matching was performed by above 3 general methods, and performances of each method were compared. As a result, LSM method realized efficient stereo matching more than other 2 methods which shown in Table 3 and Figure 5. Consequently, LSM method was adopted tching for the epipolar matching in this paper. (c) Area correlation . gH Figure 5. Results of epipolar matching igated, | Table 3.
