Ground Plane Obstacle Detection using Projective Geometry

|The problem addressed in this paper is obstacle detection in the context of mobile robot navigation using visual information. The goal is achieved by analyzing successive pairs of time varying images acquired with the TV camera mounted on the moving robot. Assuming the robot is moving on a at ground, any obstacle is identi ed by any cluster of points not coplanar with the largest number of poi...

Gravity, Geometry and Physics

Geometry is present in physics at many levels, most prominently in the theory of gravity. In these introductory lectures geometrical concepts like manifolds, geodesics, curvature and topology are introduced as a tool to describe and interpret physical phenomena in space-time, including the gravitational eld itself. The focus is not only on possible static structures, e.g. black holes, but also ...

Gravity, Geometry, and Equivalence

We show that the energy-momentum four-vector of a planet, p = mu, is conserved during geodesic motion. Therefore, there is no exchange of energymomentum with the gravitational field. We discuss the meaning of a gravitational field which is free of energy, momentum, and stress.

Coframe geometry and gravity

The possible extensions of GR for description of fermions on a curved space, for supergravity and for loop quantum gravity require a richer set of 16 independent variables. These variables can be assembled in a coframe field, i.e., a local set of four linearly independent 1-forms. In this chapter we study the gravity field models based on a coframe variable alone. We give a short review of the ...

Coframe geometry, gravity and electromagnetism

The extensions of GR for description of fermions on a curved space, for supergravity, and for the loop quantum gravity ordinary use a set of 16 independent variables instead of 10 components of metric. These variables can be assembled in a coframe field, i.e., a set of four linearly independent 1-forms. In this presentation we review a geometrical structure based on the coframe field. We constr...
