However, in practice.

**Camera model** definition. We define the **camera model** FPC with a conventional planar **pinhole camera** PPC and a sampling map SM that distorts the PPC image according to the algorithm in Figure 3. Projection. FPC(PPC, SM) projects a 3D point P to its CoNUS image plane by first projecting P with PPC to obtain (u, v) and then distorting (u, v) to (u d. 1. Every two distinct points define a line 2. Every two distinct lines define a point (intersect at a point) 3. There exists three points, A,B,C such that C does not lie on the line defined by A and B. • Different than Euclidean (affine) geometry • Projective plane is "bigger" than affine plane - includes "line at infinity". .

The area of the composite figure shown below is found by calculating the area of the rectangle and then subtracting the area of the triangle.Area of the composite figure = area of the rectangle – area. The **pinhole** **model** is the basic **camera** **model** used in computer vision. Its name stems from the concept of **pinhole** **camera** [] (also related to the **camera** obscura []): usually, a closed box into which a single tiny hole is made with a pin, through which light may enter and hit a photosensitive surface inside the box (cf. Fig. 1).Pinhole **cameras** allow to take photographs of objects, which usually.

at the **camera model** level such as the general linear **camera** [2] and the occlusion **camera** [3]. The FPC CoNUS is complemen-tary to these approaches, providing sampling rate ﬂexibility to panoramic and non-**pinhole cameras**. Irregular sampling patterns have also occurred in the con-texts of image-based rendering by 3-D warping [4] and of.

Most commercial **cameras** can be described as **pinhole** **cameras**, which are modeled by a perspective projection. However, there are projection systems whose geometry cannot be described using the conventional **pinhole** **model** be- cause of the very high distortion introduced by the imaging device. Some of these systems are omnidirectional **cameras**.

. We present a **pinhole camera model** that allows modulating the sampling rate over the field of view with great flexibility. This flexible **pinhole camera** or FPC is defined by a viewpoint (i.e. eye) and by a sampling map that specifies the sampling locations on the image plane. The FPC supports many types of data,.

The **pinhole** **camera** **model** we will discuss in this section does not include the effects of a lens. However, it turns out that it is a very good approximation to **cameras** with lenses, and the de facto **model** for **cameras**. Hence, in the following we can continue to think of our **pinhole** as an ideal **pinhole**.
