The Solar parallax with the transit of Venus
In this note I show how one can derive the timing of the four contacts of Venus with the sun disk as a function of the location of the observer and of the solar parallax with a relatively simple approximate formula whose accuracy is sufficient to process the observations of a network of observers. Two models are discussed : one, linear in the coordinates of the observer, has an accuracy of 5 to...
متن کاملPrimitive Parallax and Parallax Primitives
This paper describes an implementation of parallax depth perception designed to be a contributing unit to a distributed perceptual intelligence. The work was done in the context of the Cog project, a large-scale eeort to develop human or at least infant intelligence from the bottom up. Our implementation uses fast-approximation \good enough" region mapping and relevant motion detection over mul...
متن کاملExoplanet Transit Parallax
The timing and duration of exoplanet transits has a dependency on observer position due to parallax. In the case of an Earth-bound observer with a 2 AU baseline the dependency is typically small and slightly beyond the limits of current timing precision capabilities. However, it can become an important systematic effect in high-precision repeated transit measurements for long period systems due...
متن کاملAbout statistical-parallax algorithms
The results obtained by two algorithms of statistical parallaxes applied to a large sample of RR Lyrae stars are compared. They show no significant difference and confirm the validity of the earlier approach based on the principle of maximum likelihood.
متن کاملOn the passband of head-parallax displays
We present a methodology to assess objective visual quality of multi-view and light-field displays. We consider the display as a signal processing channel and study its ability to deliver a signal while introducing negligible distortions. We start by creating a model of a display, which represents its output as a set of rays in a specific (x, y, o) coordinate space. We created a simulation fram...
