Finally we give some indications on the construction of a cwt on other conic sections. Introduction many situations in physics, astronomy and medicine yield data on spherical manifolds. Also, some data may live on a two-sheeted hyperboloid, in cos-.
The intersection of a plane and a sphere is a circle (or is reduced to a single point, or is empty). Any ellipsoid is the image of the unit sphere under some affine transformation, and any plane is the image of some other plane under the same transformation.
Highlights we tackle the model based tracking issue in omnidirectional vision and stereovision. The new formulation is compared to a classical image plane formulation. The spherical formulation increases the convergence rate and pose precision. The extension to an unusual omnidirectional stereovision sensor increases robustness.

One way to define a conic section is to specify a line in the plane, called the directrix, and a point in the plane off of the line, called the focus. The conic section is then the set of all points whose distance to the focus is a constant times the distance to the directrix.
Conic sections are a particular type of shape formed by the intersection of a plane and a right circular cone. Depending on the angle between the plane and the cone, four different intersection shapes can be formed. The types of conic sections are circles, ellipses, hyperbolas, and parabolas.
Conic sections and standard forms of equations a conic section is the intersection of a plane and a double right circular cone by changing the angle and location of the intersection, we can produce different types of conics. There are four basic types: circles ellipses hyperbolas and parabolas none of the intersections will pass through.

For this purpose, we have to go back to the definition of spherical conic. 1(spherical conic) a spherical conic is the intersection of a sphere and an elliptic cone centered at the center of the sphere. This definition is quite different from that of ordinary conic in the plane with two foci and a string with a certain length.
A conic section a curve that is formed when a plane intersects the surface of a cone. In the figure shown below, cone 1 and cone 2 are connected at the vertex.
From this we see that all possible conics appear as hyperplane sections with the sphere will be circles on the plane (except those that pass through the north.

Like spherical aberration, coma is manifested by different radial zones in the optic unlike spherical aberration, the images produced by the zones are in sharp focus at the paraxial focal plane. Each pair of symmetric points in each radial zone produces a sharp image, but since the lateral magnification is different for each pair.

It is simple and relatively cheap to make lenses whose surfaces are parts of a plane or parts of a sphere. Such lenses do not focus light perfectly; this lack of focus is spherical aberration. This graphic from a wikipedia article schematically illustrates how the light rays fail to converge (lower half) compared to a hypothetical perfect lens.

He obtained the conic sections as intersections of this cone by a plane not through the apex. Apollonius distinguished three types of conic sections: the ellipse, the parabola, and the hyperbola.

A conic is the curve obtained as the intersection of a plane, called the cutting plane, with the surface of a double cone (a cone with two nappes). It is usually assumed that the cone is a right circular cone for the purpose of easy description, but this is not required; any double cone with some circular cross-section will suffice.

The orthogonal projected images of spherical circles are conics in the plane. On the other hand, the orthogonal projected images of spherical conics are not conic but quartic in general. To construct these figures with basic drawing tools, stereographic projection plays an important role.
If the plane is perpendicular to the axis of revolution, the conic section is a circle. If the plane intersects one nappe at an angle to the axis (other than then the conic section is an ellipse. Each conic is determined by the angle the plane makes with the axis of the cone.
The most famous case of spherical aberrations occured on the hubble space telescope. Its optical defect was corrected by making the mirror a slightly non-spherical conic section and using new imaging algorithms like the well-known deconvolution function to correct its myopia.

These classes may be further subdivided, for example conic projections can be either one-standard two-standard or poly-standard.
