INFLUENCE OF MECHANICAL ERRORS IN A ZOOM CAMERA

Autor: Alfredo Gardel, Jose Luis Lazaro, Jean Marc Lavest

Publikováno v: Image Analysis and Stereology, Vol 22, Iss 1, Pp 21-25 (2011)

As it is well known, varying the focus and zoom of a camera lens system changes the alignment of the lens components resulting in a displacement of the image centre and field of view. Thus, knowledge of how the image centre shifts may be important fo

Nowadays Rolling shutter CMOS cameras are embedded on a lot of devices. This type of cameras does not have its retina exposed simultaneously but line by line. The resulting distortions affect structure from motion methods developed for global shutter

Publikováno v: International Journal of Machine Tools and Manufacture. 48:1569-1577

The dynamic solicitations imposed on modern production machines make the rigid body hypothesis obsolete in mechanical design. To increase productivity while ensuring effector trajectory quality, numerical control of the machine has to integrate the e
