Abstract: A method for self-recalibration of a structured light vision system including a camera and a projector. A camera plane and a projector plane are defined, a Homography matrix between the camera plane and the projector plane is computed, and a translation vector and a rotation matrix are determined from Homography-based constraints. A computer vision system implementing the method is also described.

A flexible new technique for camera calibration
TL;DR: A flexible technique to easily calibrate a camera that only requires the camera to observe a planar pattern shown at a few (at least two) different orientations is proposed and advances 3D computer vision one more step from laboratory environments to real world use.

Fast and globally convergent pose estimation from video images
TL;DR: It is shown that the pose estimation problem can be formulated as that of minimizing an error metric based on collinearity in object (as opposed to image) space, and an iterative algorithm which directly computes orthogonal rotation matrices and which is globally convergent is derived.
Robust Pose Estimation from a Planar Target

TL;DR: It is shown that pose ambiguities - two distinct local minima of the according error function - exist even for cases with wide angle lenses and close range targets, and a new algorithm for unique and robust pose estimation from a planar target is developed.
