Abstract
The Number of observable facts and structures that are accessible with an airglow images which are captured by an All Sky Imager (ASI). All of these images are required to convert from the spherical coordinating system into the rectangular coordinating image system. The spatial calibration is also most important for the perfect measurement of gravity wave characteristics, plasma characteristics and OH emission parameters in the upper atmosphere, mesosphere, ionosphere study when that calibrations are used in real life dimensions. In this paper, we expressed an effective and simple technique for the coordinate mapping and the spatial calibration for accurate dimensions used in real world life and also implemented the same procedure by using Matlab R2013a. The pixel resolutions of OH image of 840 nm, a mesospheric image of 557.7 nm and ionospheric image of 630 nm are measured. These pixel resolutions are nearly same and measuring technique is very simple than other method used in the same area.
