Always be aware of lens distortion
when using these type of lenses.
Dominant role in affecting the geometric accuracy is played by the radial and tangential lens distortion
Due to wide-angle conuguration of the camera lens, Vijayan Asari and Tsai proposed aradial lens distortion
model which describes a 2-D image correction technique [3, 4].
Among his example applications are tracking a colored region, correcting lens distortion
, and real-time product grading.
In addition to that new features have been implemented including linearity and planarity constraints together with lens distortion
Their topics include image quality and accuracy in three three-dimensional scanners, a large database sample of three-dimensional facial images and measurement, the effect of three-dimensional rotation on landmark visibility, the influence of lens distortion
and perspective error, generating values for missing data, admissibility, and problems and prospects.
We present a fast technique to estimate the camera center with special arrangement of calibration target and the camera model is aimed at efficient computation of camera parameters considering lens distortion
accurate), include color balancing/correction, correction of lens distortion
, focus adjustments, glare elimination, overall lightening or darkening, and red eye elimination.
Other effects such as Zoom Blur (to imitate motion blur) and Lens Distortion
help PhotoImpact 7 in its bid to challenge Adobe Photoshop.
With the expanding use of virtually distortion-free solid-state imaging devices in cameras, lens distortion
is more apparent than ever before.
Ultra-wide angle and small form factor lenses are supported with full lens distortion
The OV480 can correct lens distortion
of up to 195-degrees and enable a single camera design to be used across multiple vehicle platforms, thus dramatically reducing the design and integration costs associated with rear-view and 360-degree surround view systems.
