Image rectification is a process of transforming a set of images into a new set such that the epipolar lines in the transformed images have the same direction as the image rows or columns to enable an efficient and reliable stereo matching. Previous algorithms for stereo image rectification either work for two view uncalibrated or two/three view calibrated situations. In this paper we propose s...

The thesis presents rectification methods of an omnidirectional stereo pair. Several methods are developed and a novel rectification method called stereographic rectification is introduced. In the second part of the thesis, a method of 3D reconstruction from a stereo pair rectified using an arbitrary method of the adduced methods is presented. Further, a method of judging the accuracy of an ess...

Background: We have developed edge-control for the Precessions TM process suitable for fast fabrication of large mirror segments, and other applications sensitive to edge mis-figure. This has been applied to processing of European extremely large telescope (E-ELT) prototype mirror-segments, meeting the specification on maximum edge mis-figure. However we have observed residuals that have proved...

In this paper, we propose a match propagation algorithm between perspective and omnidirectional images of same scene consisting of planes, which does not require a rectification for the omnidirectional image. First, a linear transformation is introduced to identify the area containing the corresponding point candidates. Then, a geometric invariant is computed as a constraint for quasi-dense mat...

In this paper, we propose a direct depth map acquisition method for a convergent camera array as well as a parallel camera array. Since image rectification is necessary for conventional stereo matching methods, disparity values are found in the same horizontal line of stereo images. Consecutively, the acquired disparity values are transformed to depth values. However, image rectification may le...
