标题: An Ellipsoid-based Perspective Projection Correction for Wide-angle Images
1 Introduction

Wide-angle images have been wisely used in many areas since they

can provide much larger field-of-view (FOV) of a scene. But distortions

in these images disturb users’ perception and many research

works have been investigated to tackle this problem. Up to now,

several correction methods have been developed, such as the perspective,

Mercator and stereographic projections. However, these

methods tend to bend straight lines or distort the shapes of objects,

and [Zorin and Barr 1995] pointed out that no global projection

can preserve both straight lines and the shapes of objects. Recently,

[Carroll et al. 2009] proposed a content-preserving approach

to map wide-angle photographs onto image plane by computing a

spatially-varying projection. Unfortunately, it required the users to

draw about 20 lines on average as an initial step.

In this paper, we present an ellipsoid-based correction method, aiming

to minimize distortions in wide-angle images. Although it may

not reach the optimal result in some cases, the flexibility of our

method makes it a useful tool in practice.
