Parallax: When the two objects are seen on a straight line, they seem to be concident. If the objects are at different places and the eye is moved side ways then there is a relative …

个人理解：disparity最小为一个像素，而parallax可以无穷小。 在立体视觉中，disparity更多的表示一个定量的概念；parallax更多的表示一个定性的概念。 发布于 2018-10-28 19:32 白云Amanda

The parallax formula states that the distance to a star is equal to 1 divided by the parallax angle, p, where p is measured in arc-seconds, and d is parsecs. d = 1 p Explanation: Parallax is a …

Explain the parallax method for measuring large distances. With the help of it, explain the method to determine the shape of a heavenly body.

There is an hinverse relation between star's parallax and its distance. A star which has a parallax 1 arcseconds is at a distance of 1 parsec, which is equal to 3.26 light years.

As the distance of star increases, the parallax angle decreases, and great degree of accuracy is required for its measurement. Keeping in view the practical limitation in measuring the parallax …

Assertion :Parallax method is used for measuring distances of nearby stars only. Reason: With increase of distance of star, parallactic angle becomes too small to be measured accurately.

Star B has large parallax angle. Because in Parallax method, the far star or any other object has less parallax angle and the close star has large parallax angle.

To minimise parallax error, the observer should place the object : as near to the scale of the ruler as possible and the eye must be directly above the scale as far ...

The parallax of a heavenly body measured from two points diametrically opposite on equator of earth is 2.0 minute. If radius of earth is 6400 km,calculate distance of heavenly body.
