A new 3D camera is designed by using a new 3D ring lens instead of
traditional lenses. The new camera has the ability to capture the 3D
information in such a way that simplifies the necessary steps for 3D
reconstruction. The new camera captures two images for every point in
its object field with a fixed geometric costraint between the
correspondence points. It is independent of any intrinsic parameter
(focal length and the coordinates of the principle point) or extrinsic
parameters (transformation and rotation of the two cameras) like
epipolar geometry of traditional stereo systems. It has the following
features:
1-It needs only one camera with the new 3D lens.
2-Since it has only one camera , there is no need to adjust the
geometry between the two cameras and hence, the mechanical effects
on the system are minimized.
3-The accuracy of the geometric costraint between the correspondence
points of the new system points is independent of false matches and
noise.
4-The estimation time for this geometry is negligible ( zero).
5-As the geometric costraint is independent of the intrinsic
parameters, we have the ability to change the parameters of the
system like focus, ....etc. without disturbing it.
The new system is suitable for many applications such as: stereo
applications (disparity/depth map estimation, 3D reconstruction, etc.)
robotics applications (vehicle navigation, object tracking, etc.) and
many other industrial applications.
