摘要
本文介绍我国在视窗环境开发的极光全天空图象处理和分析软件,该软件在对图象精确定位和极光全天空图象到地磁坐标平面展开的基础上,实现了在微机上对极光形状、位置、运动、强度等极光物理信息的定量提取。
An image processing system under MS-Windows environment has been developed on micro-computer in order to facilitate the data analyzing of all-sky auroral image recorded in polar region. The system has realized: information extraction of aurora's shape, position, motion and brightness on geomagnetic coordinate.
