Direct passive navigation: Analytical solution for planes
1. I n t r o d u c t i o n The problem of determining rigid body motion and surface structure from image data has been the topic of many research papers in the area of machine vision 11-22]. Many approaches based on tracking feature points [5,11,19,20] or contours 191, using optical flow 11,3,4,10,12,16,17,21,22], texture 121, or image intensity gradients j14,15] have been proposed in the liter...
متن کاملPassive navigation
A method is proposed for determining the motion of a body relative to a fixed environment using the changing image seen by a camera attached to the body. The optical flow in the image plane is the input, while the instantaneous rotation and translation of the body are the output. If optical flow could be determined precisely, it would only have to be known at a few places to compute the paramet...
متن کاملPassive Navigation in a Partially Known Environment
This paper presents an integrated solution to the problem of obtaining the kinematics of a moving vehicle and the 3-D locations of salient points in the external environment, based on a sequence of monoc-ular images. The structure of a small number of nav-igational landmarks in the scene is assumed to be known. The parameters of interest are expressed in an inertial, or \world" coordinate syste...
متن کاملPassive Distance Learning for Robot Navigation
Autonomous mobile robots need good models of their environment, sensors and actuators to navigate reliably and efficiently. While this information can be supplied by humans, or learned from scratch through active exploration, such approaches are tedious and time-consuming. Our approach is to provide the robot with the topological and geometrical constraints that are easily obtainable by humans,...
متن کاملPassive direct formic acid microfabricated fuel cells
This paper reports on microscale silicon-based direct formic acid fuel cells (Si-DFAFCs) in which the fuel and the oxidant are supplied to the electrodes in a passive manner. Passive delivery of fuel and oxidant eliminates the need for ancillary components and associated parasitic losses. In this Si-DFAFC, an aqueous solution of formic acid is in direct contact with a Pdor Pt-based anode and a ...
