一种基于径向和环向模式特征量的近红外星图匹配识别方法

A NIR Star Map Matching Recognition Method Based on Radial and Circle Pattern Characteristic Parameters

通过近红外星空目标分布的特征分析,对近红外恒星目标进行了径向模式特征量的构造和环向模式特征量的构造,并对经构造得到的特征库和基于标准星空坐标数据完成的星空导航匹配库进行了模式特征量的匹配识别。结果表明,这种方法在实际应用中具有一定的价值。

Both radial pattern characteristic parameters and circle pattern characteristic parameters are constructed for near infrared （NIR） star objects after their distribution characteristics are analyzed. The characteristic parameter matching recognition is carried out both for the characteristic library obtained in construction and for the starry sky navigation library based on the standard starry sky coordinate data. The result shows that this method is of a certain value in practical application.
