Mitsumoto et al. [3] describe a stereo method for obtaining a stereo image by imaging an object and its mirror reflection with a planar mirror.
Inaba et al. [4] propose a system using four planar mirrors (Fig. 1(c)), but its view becomes small.
(b) The result of reconstruction of the chess corners In order to estimate the accuracy of the reconstruction result, we caculated the errors of size in length and width direction, and the distances every reconstructed corners to their fitted plane, denoted as EL, EW, DP, separately.
The average and variance of EL, EW, DP then be obtained, as shown in Table 1.
We used AEL, AEW, ADP to represent average of EL, EW, DP, respectively.

Recently, the enhanced hybrid mean value (HMV+) method is proposed by Youn et al [4], to improve numerical stability and efficiency in the Most Probable Point (MPP) search.
In the paper of Kharmanda et al. [5], we had demonstrated that the HM reduced the computational time almost 80% relative to the classical RBDO approach.

This widely used method requires numerical procedures for its evaluation, as do the finite difference solutions of Shuja et al. [6].
